cy7c1366c, cy7c1367c document number: 38-05542 rev. *j page 7 of 32 functional overview all synchronous inputs pass through input registers controlled by the rising edge of the clock. all data outputs pass through output registers controlled by the ri sing edge of the clock. the cy7c1366c/cy7c1367c supports secondary cache in systems using either a linear or interleaved burst sequence. the interleaved burst order supports pentium and i486? processors. the linear burst sequence is suited for processors that use a linear burst sequence. the burst order is user selectable, and is determined by sampling the mode input. accesses can be initiated with either the processor address strobe (adsp ) or the controller addre ss strobe (adsc ). address advancement through the burst sequence is controlled by the adv input. a two-bit on-chip wraparound burs t counter captures the first address in a burst sequence and automatically increments the address for the rest of the burst access. byte write operations are qualified with the byte write enable (bwe ) and byte write select (bw x ) inputs. a global write enable (gw ) overrides all byte write inputs and writes data to all four bytes. all writes are simplif ied with on-chip synchronous self-timed write circuitry. synchronous chip selects ce 1 , ce 2 , ce 3 [3] and an asynchronous output enable (oe ) provide for easy bank selection and output tristate control. adsp is ignored if ce 1 is high. single read accesses this access is initiated when the following conditions are satisfied at clock rise: (1) adsp or adsc is asserted low, (2) chip selects are all asserted active, and (3) the write signals (gw , bwe ) are all deasserted high. adsp is ignored if ce 1 is high. the address presented to the address inputs is stored into the address advancement logic and the address register while being presented to the memory core. the corresponding data is allowed to propagate to the input of the output registers. at the rising edge of the next clock the data is allowed to propagate through the output register and on the data bus within t co if oe is active low. the only exception occurs when the sram is emerging from a deselected state to a selected state, its outputs are always tristated during the fi rst cycle of the access. after the first cycle of the access, the ou tputs are contro lled by the oe signal. consecutive single read cycles are supported. the cy7c1366c/cy7c1367c is a double-cycle deselect part. once the sram is deselected at clock rise by the chip select and either adsp or adsc signals, its output will tristate immediately after the next clock rise. mode input- static selects burst order . when tied to gnd selects linear burst sequence. when tied to v dd or left floating selects interleaved burst sequence. this is a strap pin and should remain static during device operation. mode pin has an internal pull-up. tdo jtag serial output synchronous serial data-out to the jtag circuit . delivers data on the negative edge of tck. if the jtag feature is not being used, this pin should be disconnected. this pin is not available on tqfp packages. tdi jtag serial input synchronous serial data-in to the jtag circuit . sampled on the rising edge of tck. if the jtag feature is not being used, this pin can be disconnected or connected to v dd . this pin is not available on tqfp packages. tms jtag serial input synchronous serial data-in to the jtag circuit . sampled on the rising edge of tck. if the jtag feature is not being used, this pin can be disconnected or connected to v dd . this pin is not available on tqfp packages. tck jtag- clock clock input to the jtag circuitry . if the jtag feature is not being used, this pin must be connected to v ss . this pin is not available on tqfp packages. nc ? no connects . not internally connected to the die.18m, 36m, 72m, 144m, 288m, 576m, and 1g are address expansion pins and are not internally connected to the die. pin definitions (continued) name i/o description note 3. ce 3 is for 100-pin tqfp. 119-ball bga is offered only in 2 chip enable.
cy7c1366c, cy7c1367c document number: 38-05542 rev. *j page 8 of 32 single write accesses initiated by adsp this access is initiated when both of the following conditions are satisfied at clo ck rise: (1) adsp is asserted low, and (2) chip select is asserted active. the address presented is loaded into the address register and the address advancement logic while being delivered to the memory core. the write signals (gw , bwe , and bw x ) and adv inputs are ignored during this first cycle. adsp triggered write accesses require two clock cycles to complete. if gw is asserted low on th e second clock rise, the data presented to the dq x inputs is written into the corresponding address location in the memory core. if gw is high, then the write operation is controlled by bwe and bw x signals. the cy7c1366c/cy7c1367c provides byte write capability that is described in the write cycle description table. asserting the byte write enable input (bwe ) with the selected byte write input will selectively write to only the desired bytes. bytes not selected during a byte write operation remain unaltered. a synchronous self-timed write mechanism is provided to simplify the write operations. because the cy7c1366c/cy7c1367c is a common i/o device, the output enable (oe ) must be deasserted high before presenting data to the dq inputs. doing so tristates the output drivers. as a safety precaution, dq are automatically tristated whenever a write cycle is detected, regardless of the state of oe . single write accesses initiated by adsc adsc write accesses are initiated when the following conditions are satisfied: (1) adsc is asserted low, (2) adsp is deasserted high, (3) chip select is asserted active, and (4) the appropriate combination of the write inputs (gw , bwe , and bw x ) are asserted active to conduct a write to the desired byte(s). adsc triggered write accesses require a single clock cycle to complete. the address presented is loaded into the address register and the address advancement logic while being delivered to the memory core. the adv input is ignored during this cycle. if a global write is conducted, the data presented to the dq x is written into the corresponding address location in the memory core. if a byte write is conduc ted, only the selected bytes are written. bytes not selected durin g a byte write operation remain unaltered. a synchronous self-timed write mechanism is provided to simplify the write operations. because the cy7c1366c/cy7c1367c is a common i/o device, the output enable (oe ) must be deasserted high before presenting data to the dq x inputs. doing so tristates the output drivers. as a safety precaution, dq x are automatically tristated whenever a write cycle is detected, regardless of the state of oe . burst sequences the cy7c1366c/cy7c1367c provides a two-bit wraparound counter, fed by a [1:0] , that implements either an interleaved or linear burst sequence. the interleaved burst sequence is designed specifically to support intel pentium applications. the linear burst sequence is designed to support processors that follow a linear burst sequence. the burst sequence is user selectable through the mode input. both read and write burst operations are supported. asserting adv low at clock rise auto matically increments the burst counter to the next address in the burst sequence. both read and write burst operations are supported. sleep mode the zz input pin is an asynchronous input. asserting zz places the sram in a power conservation ?sleep? mode. two clock cycles are required to en ter into or exit from this ?sleep? mode. while in this mode, data inte grity is guaranteed. accesses pending when entering the ?sleep? mode are not considered valid nor is the completion of the operation guaranteed. the device must be deselected prior to entering the ?sleep? mode. ce s, adsp , and adsc must remain inactive for the duration of t zzrec after the zz input returns low. interleaved burst address table (mode = floating or v dd ) first address a1:a0 second address a1:a0 third address a1:a0 fourth address a1:a0 00 01 10 11 01 00 11 10 10 11 00 01 11 10 01 00 linear burst address table (mode = gnd) first address a1:a0 second address a1:a0 third address a1:a0 fourth address a1:a0 00 01 10 11 01 10 11 00 10 11 00 01 11 00 01 10 zz mode electrical characteristics parameter description test conditions min max unit i ddzz sleep mode standby current zz > v dd ? ? 0.2 v ? 50 ma t zzs device operation to zz zz > v dd ? 0.2 v ? 2t cyc ns t zzrec zz recovery time zz < 0.2 v 2t cyc ?ns t zzi zz active to sleep current th is parameter is sampled ? 2t cyc ns t rzzi zz inactive to exit sleep current this parameter is sampled 0 ? ns

cy7c1366c, cy7c1367c document number: 38-05542 rev. *j page 10 of 32 ieee 1149.1 serial boundary scan (jtag) the cy7c1366c incorporates a serial boundary scan test access port (tap) in the bga package only. the tqfp package does not offer this functionality. this part operates in accordance with ieee standard 1149.1-1900, but does not have the set of functions required for full 1149.1 compliance. these functions from the ieee specification are excluded because their inclusion places an added delay in the critical speed path of the sram. note that the tap controller func tions in a manner that does not conflict with the operation of other devices using 1149.1 fully compliant taps. the tap operates using jedec-standard 3.3 v or 2.5 v i/o logic levels. the cy7c1366c contains a tap controller, instruction register, boundary scan register, bypass register, and id register. disabling the jtag feature it is possible to operate the sram without using the jtag feature. to disable the tap co ntroller, tck must be tied low (v ss ) to prevent clocking of the device. tdi and tms are internally pulled up and may be unconnected. they may alternately be connected to v dd through a pull-up resistor. tdo should be left unconnected. upon power-up, the device comes up in a reset state which does not interfere with the operation of the device. test access port (tap) test clock (tck) the test clock is used only with the tap controller. all inputs are captured on the rising edge of tc k. all outputs are driven from the falling edge of tck. test mode select (tms) the tms input is used to give commands to the tap controller and is sampled on the rising edge of tck. it is allowable to leave this ball unconnected if the tap is not used. the ball is pulled up internally, resulting in a logic high level. test data-in (tdi) the tdi ball is used to serially input information into the registers and can be connected to the input of any of the registers. the register between tdi and tdo is chosen by the instruction that is loaded into the tap instruction register. for information about loading the instruction register, see the tap controller state diagram on page 12 . tdi is internally pulled up and can be unconnected if the tap is unus ed in an application. tdi is connected to the most signific ant bit (msb) of any register. test data-out (tdo) the tdo output ball is used to serially clock data-out from the registers. the output is active depending upon the current state of the tap state machine (see identification codes on page 16 ). the output changes on the falling edge of tck. tdo is connected to the least significant bit (lsb) of any register. performing a tap reset a reset is performed by forcing tms high (v dd ) for five rising edges of tck. this reset does not affect the operation of the sram and may be performed while the sram is operating. at power up, the tap is reset internally to ensure that tdo comes up in a high z state. tap registers registers are connected betw een the tdi and tdo balls and enable data to be scanned into and out of the sram test circuitry. only one register can be selected at a time through the instruction register. data is serially loaded into the tdi ball on the rising edge of tck. data is output on the tdo ball on the falling edge of tck. instruction register three-bit instructions can be serially loaded into the instruction register. this register is loaded when it is placed between the tdi and tdo balls as shown in the tap controller block diagram on page 13 . upon power-up, the instruction register is loaded with the idcode instruction. it is also loaded with the idcode instruction if the controller is placed in a reset state as described in the previous section. when the tap controller is in th e capture-ir state, the two least significant bits are loaded with a binary ?01? pattern to enable fault isolation of the board-level serial test data path. bypass register to save time when serially shifting data through registers, it is sometimes advantageous to skip certain chips. the bypass register is a single-bit register that can be placed between the tdi and tdo balls. this enables data to be shifted through the sram with minimal delay. the by pass register is set low (v ss ) when the bypass instruction is executed. boundary scan register the boundary scan register is connected to all the input and bidirectional balls on the sram. the boundary scan register is loaded with the contents of the ram i/o ring when the tap controll er is in the capture-dr state and is then placed between the tdi and tdo balls when the controller is moved to the shift-dr state. the extest, sample/preload and sample z instructions can be used to capture the contents of the i/o ring. the boundary scan order on page 17 show the order in which the bits are connected. each bit corresponds to one of the bumps on the sram package. the msb of the register is connected to tdi and the lsb is connected to tdo. identification (id) register the id register is loaded with a vendor-specific, 32-bit code during the capture-dr state when the idcode command is loaded in the instruction register . the idcode is hardwired into the sram and can be shifted out when the tap controller is in the shift-dr state. the id regist er has a vendor code and other information described in identification register definitions on page 16 .
cy7c1366c, cy7c1367c document number: 38-05542 rev. *j page 11 of 32 tap instruction set overview eight different instructions are possible with the three-bit instruction register. all co mbinations are listed in identification codes on page 16 . three of these instructions are listed as reserved and should not be used. the other five instructions are described in detail in this section. the tap controller used in this sram is not fully compliant to the 1149.1 convention because some of the mandatory 1149.1 instructions are not fully implemented. the tap controller cannot be used to load address data or control signals into the sram and cannot preload the i/o buffers. the sram does not implement the 1149.1 commands extest or intest or the preload portion of sample/preload; rather, it performs a captur e of the i/o ring when these instructions are executed. instructions are loaded into the tap controller during the shift-ir state when the instruction register is placed between tdi and tdo. during this state, instructions are shifted through the instruction register through the tdi and tdo balls. to execute the instruction once it is shifted in, the tap controller needs to be moved into the update-ir state. extest extest is a mandatory 1149.1 instruction which is to be executed whenever the instruction r egister is loaded with all 0s. extest is not implemented in this sram tap controller, and therefore this device is not compliant to 1149.1. the tap controller does recognize an all-0 instruction. when an extest instruction is loaded into the instruction register, the sram respond s as if a sample/preload instruction has been loaded. there is one difference between the two instructions. unlike the sample/preload instruction, extest places the sram outputs in a high z state. idcode the idcode instruction causes a vendor-specific, 32-bit code to be loaded into the instruction register. it also places the instruction register between the tdi and tdo balls and allows the idcode to be shifted out of the device when the tap controller enters the shift-dr state. the idcode instruction is loade d into the instruction register upon power up or whenever the tap controller is given a test logic reset state. sample z the sample z instruction causes the boundary scan register to be connected between the tdi and tdo balls when the tap controller is in a shift-dr state. it also places all sram outputs into a high z state. sample/preload sample/preload is a 1149.1 mandatory instruction. when the sample/preload instruct ions are loaded into the instruction register and the tap controller is in the capture-dr state, a snapshot of data on the inputs and output pins is captured in the boundary scan register. the user must be aware that the tap controller clock can only operate at a frequency up to 20 mhz, while the sram clock operates more than an order of magnitude faster. because there is a large difference in the clock frequencies, it is possible that during the capture-dr state, an input or output undergoes a transition. the tap may then tr y to capture a signal while in transition (metastable state). this does not harm the device, but there is no guarantee as to the value that is captured. repeatable results may not be possible. to guarantee that the boundary scan register captures the correct value of a signal, the sram signal must be stabilized long enough to meet the tap controller?s capture setup plus hold times (t cs and t ch ). the sram clock input might not be captured correctly if there is no way in a design to stop (or slow) the clock during a sample/preload instruction. if this is an issue, it is still possible to capture all othe r signals and simply ignore the value of the ck and ck# captur ed in the boundary scan register. once the data is captured, it is possible to shift out the data by putting the tap into the shift-dr state. this places the boundary scan register between the tdi and tdo pins. preload enables an initial data pattern to be placed at the latched parallel outputs of the boun dary scan register cells prior to the selection of another boundary scan test operation. the shifting of data for the sample and preload phases can occur concurrently when requir ed - that is, while data captured is shifted out, the preloaded data can be shifted in. bypass when the bypass instruction is loaded in the instruction register and the tap is placed in a shift- dr state, the bypass register is placed between the tdi and tdo balls. the advantage of the bypass instruction is that it shortens the boundary scan path when multiple devices are connected together on a board. reserved these instructions are not im plemented but are reserved for future use. do not use these instructions.
