1-6 phase lock loop (pll) 1.5 phase lock loop (pll) 1.6 external memory expansion port (port a) note: when the dsp56301 enters a low-power stand-by mode (stop or wait), it releases bus mastership and tri-states the relevant port a signals: a[0C23] , d[0C23] , aa0/ras0 C aa3/ras3 , rd , wr , bb , cas , bclk , and bclk . if hardware refresh of external dram is enabled, port a exits the wait mode to allow the refresh to occur and then returns to the wait mode. 1.6.1 external address bus table 1-5. phase lock loop signals signal name type state during reset signal description clkout output chip-driven clock output provides an output clock synchronized to the internal core clock phase. if the pll is enabled and both the multiplication and division factors equal one, then clkout is also synchronized to extal. if the pll is disabled, the clkout frequency is half the frequency of extal. pcap input input pll capacitor connects an off-chip capacitor to the pll filter. connect one capacitor terminal to pcap and the other terminal to v ccp . if the pll is not used, pcap can be tied to v cc , gnd, or left floating. pinit/nmi input input pll initial/non-maskable interrupt during assertion of reset , the value of pinit/nmi is written into the pll enable (pen) bit of the pll control register, determining whether the pll is enabled or disabled. after reset deassertion and during normal instruction processing, the pinit/nmi schmitt-trigger input is a negative-edge-triggered non-maskable interrupt (nmi) request internally synchronized to clkout. pinit/nmi can tolerate 5 v. table 1-6. external address bus signals signal name type state during reset signal description a[0C23] output tri-stated address bus when the dsp is the bus master, a[0C23] specify the address for external program and data memory accesses. otherwise, the signals are tri-stated. to minimize power dissipation, a[0C23] do not change state when external memory spaces are not being accessed.
1-7 external memory expansion port (port a) 1.6.2 external data bus 1.6.3 external bus control table 1-7. external data bus signals signal name type state during reset signal description d[0C23] input/output tri-stated data bus when the dsp is the bus master, d[0C23] provide the bidirectional data bus for external program and data memory accesses. otherwise, d[0C23] are tri-stated. table 1-8. external bus control signals signal name type state during reset signal description aa0/ras0 C aa3/ras3 output tri-stated address attribute or row address strobe as aa, these signals function as chip selects or additional address lines. unlike address lines, however, the aa lines do not hold their state after a read or write operation. as ras , these signals can be used for dynamic random access memory (dram) interface. these signals have programmable polarity. rd output tri-stated read enable when the dsp is the bus master, rd is asserted to read external memory on the data bus (d[0C23]). otherwise, rd is tri-stated. wr output tri-stated write enable when the dsp is the bus master, wr is asserted to write external memory on the data bus (d[0C23]). otherwise, wr is tri-stated. ta input ignored input transfer acknowledge if the dsp56301 is the bus master and there is no external bus activity, or the dsp56301 is not the bus master, the ta input is ignored. the ta input is a data transfer acknowledge (dtack) function that can extend an external bus cycle indefinitely. any number of wait states (1, 2,..., infinity) can be added to the wait states inserted by the bcr by keeping ta deasserted. in typical operation, ta is deasserted at the start of a bus cycle, asserted to enable completion of the bus cycle, and deasserted before the next bus cycle. the current bus cycle completes one clock period after ta is asserted synchronous to clkout. the number of wait states is determined by the ta input or by the bus control register (bcr), whichever is longer. the bcr can set the minimum number of wait states in external bus cycles. to use the ta functionality, the bcr must be programmed to at least one wait state. a zero wait state access cannot be extended by ta deassertion; otherwise improper operation may result. ta can operate synchronously or asynchronously, depending on the setting of the tas bit in the operating mode register (omr). ta functionality cannot be used during dram-type accesses; otherwise improper operation may result.
1-8 external memory expansion port (port a) br output output (deasserted) bus request asserted when the dsp requests bus mastership and deasserted when the dsp no longer needs the bus. br can be asserted or deasserted independently of whether the dsp56301 is a bus master or a bus slave. bus parking allows br to be deasserted even though the dsp56301 is the bus master (see the description of bus parking in the bb signal description). the bus request hole (brh) bit in the bcr allows br to be asserted under software control, even though the dsp does not need the bus. br is typically sent to an external bus arbitrator that controls the priority, parking and tenure of each master on the same external bus. br is affected only by dsp requests for the external bus, never for the internal bus. during hardware reset, br is deasserted and the arbitration is reset to the bus slave state. bg input ignored input bus grant must be asserted/deasserted synchronous to clkout for proper operation. an external bus arbitration circuit asserts bg when the dsp56301 becomes the next bus master. when bg is asserted, the dsp56301 must wait until bb is deasserted before taking bus mastership. when bg is deasserted, bus mastership is typically given up at the end of the current bus cycle. this may occur in the middle of an instruction that requires more than one external bus cycle for execution. bb input/ output input bus busy indicates that the bus is active and must be asserted and deasserted synchronous to clkout. only after bb is deasserted can the pending bus master become the bus master (and then assert the signal again). the bus master can keep bb asserted after ceasing bus activity, regardless of whether br is asserted or deasserted. this is called bus parking and allows the current bus master to reuse the bus without re-arbitration until another device requires the bus. bb is deasserted by an active pull-up method (that is, bb is driven high and then released and held high by an external pull-up resistor). bb requires an external pull-up resistor. bl output driven high (deasserted) bus lock bl is asserted at the start of an external divisible read-modify-write (rmw) bus cycle, remains asserted between the read and write cycles, and is deasserted at the end of the write bus cycle. this provides an early bus start signal for the bus controller. bl may be used to resource lock an external multi-port memory for secure semaphore updates. early deassertion provides an early bus end signal useful for external bus control. if the external bus is not used during an instruction cycle, bl remains deasserted until the next external indivisible rmw cycle. the only instructions that assert bl automatically are the bset, clr, and bchg instructions when they are used to modify external memory. an operation can also assert bl by setting the blh bit in the bus control register. table 1-8. external bus control signals (continued) signal name type state during reset signal description

1-11 host interface (hi32) 1.8 host interface (hi32) the host interface (hi32) provides fast parallel data to a 32-bit port directly connected to the host bus. the hi32 supports a variety of standard buses and directly connects to a pci bus and a number of industry-standard microcomputers, microprocessors, dsps, and dma hardware. 1.8.4 host port usage considerations careful synchronization is required when the system reads multiple-bit registers that are written by another asynchronous system. this is a common problem when two asynchronous systems are connected (as they are in the host port). the considerations for proper operation are discussed in table 1-10 . reset input input reset deassertion of reset is internally synchronized to the clock out (clkout). when asserted, the chip is placed in the reset state and the internal phase generator is reset. the schmitt-trigger input allows a slowly rising input (such as a capacitor charging) to reset the chip reliably. if reset is deasserted synchronous to clkout, exact start-up timing is guaranteed, allowing multiple processors to start synchronously and operate together in lock-step. when the reset signal is deasserted, the initial chip operating mode is latched from the moda, modb, modc, and modd inputs. the reset signal must be asserted after power-up. this input is 5 v tolerant. table 1-10. host port usage considerations action description asynchronous read of receive byte registers when reading the receive byte registers, receive register high (rxh), receive register middle (rxm), or receive register low (rxl), use interrupts or poll the receive register data full (rxdf) flag that indicates data is available. this assures that the data in the receive byte registers is valid. asynchronous write to transmit byte registers do not write to the transmit byte registers, transmit register high (txh), transmit register middle (txm), or transmit register low (txl), unless the transmit register data empty (txde) bit is set, indicating that the transmit byte registers are empty. this guarantees that the transmit byte registers transfer valid data to the host receive (hrx) register. asynchronous write to host vector change the host vector (hv) register only when the host command bit (hc) is clear. this practice guarantees that the dsp interrupt control logic receives a stable vector. table 1-9. interrupt and mode control (continued) signal name type state during reset signal description

2-1 chapter 2 specifications 2.1 introduction the dsp56301 is fabricated in high-density cmos with transistor-transistor logic (ttl) compatible inputs and outputs. 2.2 maximum ratings note: in the calculation of timing requirements, adding a maximum value of one specification to a minimum value of another specification does not yield a reasonable sum. a maximum specification is calculated using a worst case variation of process parameter values in one direction. the minimum specification is calculated using the worst case for the same parameters in the opposite direction. therefore, a maximum value for a specification never occurs in the same device that has a minimum value for another specification; adding a maximum to a minimum represents a condition that can never exist. caution this device contains circuitry protecting against damage due to high static voltage or electrical fields; however, normal precautions should be taken to avoid exceeding maximum voltage ratings. reliability is enhanced if unused inputs are tied to an appropriate logic voltage level (for example, either gnd or v cc ).

2-16 ac electrical characteristics 2.6.5.2 dram timing the selection guides in figure 2-14 and figure 2-17 are for primary selection only. final selection should be based on the timing in the following tables. for example, the selection guide suggests that four wait states must be used for 100 mhz operation in page mode dram. however, using the information in the appropriate table, a designer could choose to evaluate whether fewer wait states might be used by determining which timing prevents operation at 100 mhz, by running the chip at a slightly lower frequency (for example, 95 mhz), by using faster dram (if it becomes available), and by manipulating control factors such as capacitive and resistive load to improve overall system performance. figure 2-14. dram page mode wait states selection guide chip frequency (mhz) dram type (t rac ns) 100 80 70 60 40 66 80 100 1 wait state 2 wait states 3 wait states 4 wait states note: this figure should be used for primary selection. for exact and detailed timings see the following tables. 50 120

2-33 ac electrical characteristics 2.6.5.5 asynchronous bus arbitrations timings the asynchronous bus arbitration is enabled by internal bb inputs and synchronization circuits on bg . these synchronization circuits add delay from the external signal until it is exposed to internal logic. as a result of this delay, a dsp56300 part can assume mastership and assert bb , for some time after bg is deasserted. timing 250 defines when bb can be asserted. once bb is asserted, there is a synchronization delay from bb assertion to the time this assertion is exposed to other dsp56300 components which are potential masters on the same bus. if bg input is asserted before that time, a situation of bg asserted, and bb deasserted, can cause another dsp56300 component to assume mastership at the same time. therefore, a non-overlap period between one bg input active to another bg input active is required. timing 251 ensures that such a situation is avoided. table 2-17. asynchronous bus arbitration timing 1,3 no. characteristics expression 80 mhz 100 mhz 2 unit min max min max 250 bb assertion window from bg input deassertion 4 2.5 tc + 5 2530 ns 251 delay from bb assertion to bg assertion 4 2 tc + 5 25 25 ns notes: 1. bit 13 in the operating mode register must be set to enter asynchronous arbitration mode. 2. asynchronous arbitration mode is recommended for operation at 100 mhz. 3. if asynchronous arbitration mode is active, none of the timings in table 2-16 is required. 4. in order to guarantee timings 250, and 251, bg inputs must be asserted to different dsp56300 devices on the same bus in the non-overlap manner shown in figure 2-26 . figure 2-26. asynchronous bus arbitration timing bg1 bb 251 bg2 250 250+251

4-1 chapter 4 design considerations 4.1 thermal design considerations an estimate of the chip junction temperature, t j , in c can be obtained from this equation: equation 1: where: t a = ambient temperature c r q ja = package junction-to-ambient thermal resistance c/w p d = power dissipation in package historically, thermal resistance has been expressed as the sum of a junction-to-case thermal resistance and a case-to-ambient thermal resistance, as in this equation: equation 2: where: r q ja = package junction-to-ambient thermal resistance c/w r q jc = package junction-to-case thermal resistance c/w r q ca = package case-to-ambient thermal resistance c/w r q jc is device-related and cannot be influenced by the user. the user controls the thermal environment to change the case-to-ambient thermal resistance, r q ca . for example, the user can change the air flow around the device, add a heat sink, change the mounting arrangement on the printed circuit board (pcb) or otherwise change the thermal dissipation capability of the area surrounding the device on a pcb. this model is most useful for ceramic packages with heat sinks; some 90 percent of the heat flow is dissipated through the case to the heat sink and out to the ambient environment. for ceramic packages, in situations where the heat flow is split between a path to the case and an alternate path through the pcb, analysis of the device thermal performance may need the additional modeling capability of a system-level thermal simulation tool. the thermal performance of plastic packages is more dependent on the temperature of the pcb to which the package is mounted. again, if the estimates obtained from r q ja do not satisfactorily answer whether the thermal performance is adequate, a system-level model may be appropriate. t j t a p d r q ja () + = r q ja r q jc r q ca + =
4-2 electrical design considerations a complicating factor is the existence of three common ways to determine the junction-to-case thermal resistance in plastic packages. ? to minimize temperature variation across the surface, the thermal resistance is measured from the junction to the outside surface of the package (case) closest to the chip mounting area when that surface has a proper heat sink. ? to define a value approximately equal to a junction-to-board thermal resistance, the thermal resistance is measured from the junction to the point at which the leads attach to the case. ? if the temperature of the package case (t t ) is determined by a thermocouple, thermal resistance is computed from the value obtained by the equation (t j C t t )/p d . as noted earlier, the junction-to-case thermal resistances quoted in this data sheet are determined using the first definition. from a practical standpoint, that value is also suitable to determine the junction temperature from a case thermocouple reading in forced convection environments. in natural convection, the use of the junction-to-case thermal resistance to estimate junction temperature from a thermocouple reading on the case of the package will yield an estimate of a junction temperature slightly higher than actual temperature. hence, the new thermal metric, thermal characterization parameter or y jt , has been defined to be (t j C t t )/p d . this value gives a better estimate of the junction temperature in natural convection when the surface temperature of the package is used. remember that surface temperature readings of packages are subject to significant errors caused by inadequate attachment of the sensor to the surface and to errors caused by heat loss to the sensor. the recommended technique is to attach a 40-gauge thermocouple wire and bead to the top center of the package with thermally conductive epoxy. 4.2 electrical design considerations caution this device contains protective circuitry to guard against damage due to high static voltage or electrical fields. however, normal precautions are advised to avoid application of any voltages higher than maximum rated voltages to this high-impedance circuit. reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (for example, either gnd or v cc ).
4-3 power consumption considerations use the following list of recommendations to ensure correct dsp operation. ? provide a low-impedance path from the board power supply to each v cc pin on the dsp and from the board ground to each gnd pin. ? use at least six 0.01C0.1 m f bypass capacitors positioned as close as possible to the four sides of the package to connect the v cc power source to gnd . ? ensure that capacitor leads and associated printed circuit traces that connect to the chip v cc and gnd pins are less than 0.5 inch per capacitor lead. ? use at least a four-layer pcb with two inner layers for v cc and gnd . ? because the dsp output signals have fast rise and fall times, pcb trace lengths should be minimal. this recommendation particularly applies to the address and data buses as well as the irqa , irqb , irqc , irqd , ta , and bg pins. maximum pcb trace lengths on the order of 6 inches are recommended. ? consider all device loads as well as parasitic capacitance due to pcb traces when you calculate capacitance. this is especially critical in systems with higher capacitive loads that could create higher transient currents in the v cc and gnd circuits. ? all inputs must be terminated (that is, not allowed to float) by cmos levels except for the three pins with internal pull-up resistors ( trst , tms , de ). ? take special care to minimize noise levels on the v ccp , gnd p , and gnd p1 pins. ? the following pins must be asserted after power-up: reset and trst . ? if multiple dsp devices are on the same board, check for cross-talk or excessive spikes on the supplies due to synchronous operation of the devices. ? reset must be asserted when the chip is powered up. a stable extal signal should be supplied before deassertion of reset . ? at power-up, ensure that the voltage difference between the 5 v tolerant pins and the chip v cc never exceeds 3.5 v. 4.3 power consumption considerations power dissipation is a key issue in portable dsp applications. some of the factors affecting current consumption are described in this section. most of the current consumed by cmos devices is alternating current (ac), which is charging and discharging the capacitances of the pins and internal nodes. current consumption is described by this formula: equation 3: where: c = node/pin capacitance v = voltage swing f = frequency of node/pin toggle equation 4: the maximum internal current (i cci max) value reflects the typical possible switching of the internal buses on best-case operation conditionsnot necessarily a real application case. the typical internal current (i ccityp ) value reflects the average switching of the internal buses on typical operating conditions. example 4-1. current consumption for a port a address pin loaded with 50 pf capacitance, operating at 3.3 v, with a 66 mhz clock, toggling at its maximum possible rate (33 mhz), the current consumption is expressed in equation 4 . icvf = i 50 10 12 C 3.3 33 10 6 5.48 ma ==
4-4 pll performance issues perform the following steps for applications that require very low current consumption: 1. set the ebd bit when you are not accessing external memory. 2. minimize external memory accesses, and use internal memory accesses. 3. minimize the number of pins that are switching. 4. minimize the capacitive load on the pins. 5. connect the unused inputs to pull-up or pull-down resistors. 6. disable unused peripherals. 7. disable unused pin activity (for example, clkout, xtal). one way to evaluate power consumption is to use a current-per-mips measurement methodology to minimize specific board effects (that is, to compensate for measured board current not caused by the dsp). a benchmark power consumption test algorithm is listed in appendix a . use the test algorithm, specific test current measurements, and the following equation to derive the current-per-mips value. equation 5: where: i typf2 = current at f2 i typf1 = current at f1 f2 = high frequency (any specified operating frequency) f1 = low frequency (any specified operating frequency lower than f2) note: f1 should be significantly less than f2. for example, f2 could be 66 mhz and f1 could be 33 mhz. the degree of difference between f1 and f2 determines the amount of precision with which the current rating can be determined for an application. 4.4 pll performance issues the following explanations should be considered as general observations on expected pll behavior. there is no test that replicates these exact numbers. these observations were measured on a limited number of parts and were not verified over the entire temperature and voltage ranges. 4.4.1 phase skew performance the phase skew of the pll is defined as the time difference between the falling edges of extal and clkout for a given capacitive load on clkout, over the entire process, temperature and voltage ranges. as defined in figure 2-2 , external clock timing , on page 2-5 for input frequencies greater than 15 mhz and the mf 4, this skew is greater than or equal to 0.0 ns and less than 1.8 ns; otherwise, this skew is not guaranteed. however, for mf < 10 and input frequencies greater than 10 mhz, this skew is between - 1.4 ns and +3.2 ns. 4.4.2 phase jitter performance the phase jitter of the pll is defined as the variations in the skew between the falling edges of extal and clkout for a given device in specific temperature, voltage, input frequency, mf, and capacitive load on clkout. these variations are a result of the pll locking mechanism. for input frequencies greater than 15 mhz and mf 4, this jitter is less than 0.6 ns; otherwise, this jitter is not guaranteed. however, for mf < 10 and input frequencies greater than 10 mhz, this jitter is less than 2 ns. i mips i mhz i typf2 i typf1 C () f2 f1 C () ==
4-5 input (extal) jitter requirements 4.4.3 frequency jitter performance the frequency jitter of the pll is defined as the variation of the frequency of clkout. for small mf (mf < 10) this jitter is smaller than 0.5 per cent. for mid-range mf (10 < mf < 500) this jitter is between 0.5 per cent and approximately 2 per cent. for large mf (mf > 500), the frequency jitter is 2C3 per cent. 4.5 input (extal) jitter requirements the allowed jitter on the frequency of extal is 0.5 percent. if the rate of change of the frequency of extal is slow (that is, it does not jump between the minimum and maximum values in one cycle) or the frequency of the jitter is fast (that is, it does not stay at an extreme value for a long time), then the allowed jitter can be 2 percent. the phase and frequency jitter performance results are valid only if the input jitter is less than the prescribed values.
