fullflex document number: 38-06082 rev. *h page 10 of 52 selectable io standard the fullflex device families offer the option to choose one of the four port standards for the device. each port independently selects standards from single ended hstl class i, single ended lvttl, 2.5v lvcmos, or 1.8v lvcmos. the selection of the standard is determined by the portstd pins for each port. these pins must be connected to an lvttl power suppy. this determines the input clock, addr ess, control, data, and echo clock standard for each port as shown in ta b l e 1 . clocking separate clocks synchronize the operations on each port. each port has one clock input c. in this mode, all the transactions on the address, control, and data are on the c rising edge. all trans- actions on the address, control, data input, output, and byte enables occur on the c rising edge. selectable pipelined or flow through mode to meet data rate and throughput requirements, the fullflex families offer selectable pipelined or flow through mode. echo clocks are not supported in flow through mode and the dll must be disabled. flow through mode is selected by the ftsel pin. strapping this pin high selects pipelined mode. strapping this pin low selects flow through mode. dll the fullflex familes of devices have an on-chip dll. enabling the dll reduces the clock to data valid (t cd ) time enabling more setup time for the receiving device. for operation below 100 mhz, the dll must be disabled. this is selectable by strapping lowspd low. whenever the operating frequency is altered beyond the clock input cycle to cycle jitter specif ication, reset the dll, followed by 1024 clocks before any valid operation. lowspd pins are used to reset the dlls for a single port independent of all other circuitry. mrst is used to reset all dlls on the chip. for more informati on on dll lock and reset time, see master reset on page 17. echo clocking as the speed of data increases, on-board delays caused by parasitics make it extremely difficult to provide accurate clock trees. to counter this problem, the fullflex families incorporate echo clocks. echo clocks are enabled on a per port basis. the dual port receives input clocks that are used to clock in the address and control signals for a read operation. the dual port retransmits the input clocks relative to the data output. the buffered clocks are provided on the cq1/cq1 and cq0/cq0 outputs. each port has a pair of echo clocks. each clock is associated with half the data bits. the output clock matches the corresponding ports io configuration. to enable echo clock outputs, tie cqen high. to disable echo clock outputs, tie cqen low. deterministic access control deterministic access control is provided for ease of design. the circuitry detects when both port s access the same location and provides an external busy flag to the port on which data is corrupted. the collision detection logic saves the address in conflict (busy address) to a re adable register. in the case of multiple collisions, the first busy address is written to the busy address register. if both ports access the same location at the same time and only one port is doing a write, if t ccs is met, then the data written to and read from the address is vali d data. for example, if the right port is reading and the left port is writing and the left ports clock meets t ccs , then the data read from the address by the right port is the old data. in the same case, if the right ports clock meets t ccs , then the data read out of the address from the right port is the new data. in the above case, if t ccs is violated by the either ports clock with respect to the other port and the right port gets the external busy flag, the data from the right port is corrupted. table 3 on page 11 shows the t ccs timing that must be met to guarantee the data. table 4 on page 11 shows that, in the case of the left port writing and the right port reading, when an external busy flag is asserted on the right port, the da ta read out of the device is not guaranteed. the value in the busy address register is read back to the address lines. the required input control signals for this function are shown in table 7 on page 13. the value in the busy address register is read out to the address lines t ca after the same amount of latency as a data read operation. after an initial address match, the busy flag is asserted and the address under contention is saved in the busy address register. all the following table 1. port standard selection portstd1 portstd0 i/o standard vss vss lvttl vss vttl hstl vttl vss 2.5v lvcmos vttl vttl 1.8v lvcmos table 2. data pin assignment be pin name data pin name be [7] dq[71:63] be [6] dq[62:54] be [5] dq[53:45] be [4] dq[44:36] be [3] dq[35:27] be [2] dq[26:18] be [1] dq[17:9] be [0] dq[8:0] figure 6. sdr echo clock delay input clock echo clock data out echo clock [+] feedback

fullflex document number: 38-06082 rev. *h page 12 of 52 address counter and mask register operations [1] each port of the fullflex family contains a programmable burst address counter. the burst counte r contains four registers: a counter register, a mask register, a mirror register, and a busy address register. the counter register contains the address used to access the ram array. it is changed only by the master reset (mrst ), counter reset, counter load, retransmit, and counter increment operations. the mask register value affects the counter increment and counter reset operations by pr eventing the corresponding bits of the counter register from changing. it also affects the counter interrupt output (cntint ). the mask register is only changed by mask reset, mask load, and mrst . the mask load operation loads the value of the address bus into the mask register. the mask register defines the counting range of the counter register. the mask register is divided into two or three consecutive regions. zero or more 0s define the masked region and one or more 1s define the unmasked portion of the counter register. the counter register may be divided up to three regions. the region containing the least significant bits must be no more than two 0s. bits one and zero may be 10 respectively, masking the least significant counter bit and caus ing the counter to increment by two instead of one. if bits one and zero are 00, the two least significant bits are masked and the counter increments by four instead of one. for example, in the case of a 256kx72 configu- ration, a mask register value of 003fc divides the mask register into three regions. with bit 0 being the least significant bit and bit 17 being the most significant bit, the two least significant bits are masked, the next eight bits are unmasked, and the remaining bits are masked. the mirror register reloads a counter register on retransmit operations (see retransmit on page 14) and wrap functions (see counter interrupt on page 14 below). the last value loaded into the counter register is stored in the mirror register. the mirror register is only changed by master reset (mrst ), counter reset, and counter load. table 7 on page 13 summarizes the operations of these registers and the required input control signals. all signals except mrst are synchronized to the ports clock. counter load operation [1] the address counter and mirror registers are loaded with the address value presented on the address lines. this value ranges from 0 to 1fffff. mask load operation [1] the mask register is loaded wit h the address value presented on the address bus. this value range s from 0 to 1fffff though not all values permit correct increment operations. permitted values are in the form of 2 n ?1, 2 n ?2, or 2 n ?4. the counter register is only segmented up to three regions. from the most significant bit to the least significant bit, permitted values have zero or more 0s, one or more 1s, and the least significant two bits are 11, 10, or 00. thus 1ffffe, 07ffff, and 003ffc are permitted values but 02ffff, 003ffa, and 07ffe4 are not. counter readback operation the internal value of the counter register is read out on the address lines. the address is valid t ca after the selected number of latency cycles configured by ftsel . the data bus (dq) is tri-stated on the cycle that t he address is presented on the address lines. figure 7 on page 15 shows a block diagram of this logic. mask readback operation the internal value of the mask register is read out on the address lines. the address is valid t ca after the selected number of latency cycles configured by ftsel . the data bus (dq) is tri-stated on the cycle that t he address is presented on the address lines. figure 7 on page 15 shows a block diagram of the operation. counter reset operation all unmasked bits of the counter and mirror registers are reset to ?0?. all masked bits remain unchanged. a mask reset followed by a counter reset resets the counter and mirror registers to 00000. mask reset operation the mask register is reset to all 1s, that unmasks every bit of the burst counter.

fullflex document number: 38-06082 rev. *h page 14 of 52 increment operation [1] after the address counter is initially loaded with an external address, the counter can internally increment the address value and address the entire memory array. only the unmasked bits of the counter register are incremented. for a counter bit to change, the corresponding bit in the mask register must be 1. if the two least significant bits of the mask register are 11, the burst counter increments by one. if the two least significant bits are 10, the burst counter increments by two, and if they are 00, the burst counter increments by four. if all unmasked counter bits are incremented to 1 and wrp is deasserted, the next increment l wraps the counter back to the initially loaded value. the cycle before the increment that results in all unmasked counter bits to become 1s, a counter interrupt flag (cntint ) is asserted if the counter is incremented again. this increment causes the counter to reach its maximum value and the next increment returns the counter register to its initial value that was stored in the mirror register if wrp is deasserted. if wrp is asserted, the unmasked portion of the counter is filled with 0 instead. the example shown in figure 8 on page 16 shows an example of the cydd36s18v18 device with the mask register loaded with a mask value of 00007f unmasking the seven least significant bits. setting the mask register to this value enables the counter to access the entire memory space. the address counter is then loaded with an initial value of 000005 assuming wrp is deasserted. the masked bits, the seventh address through the twenty-first address, do not incr ement in an increment operation. the counter address starts at address 000005 and increments its internal address value until it reaches the mask register value of 00007f. the counter wraps around the memory block to location 000005 at the next count. cntint is issued when the counter reaches the maximum ?1 count. hold operation the value of all three registers is constantly maintained unchanged for an unlimited number of clock cycles. this operation is useful in applicati ons where wait states are needed or when address is available a few cycles ahead of data in a shared bus interface. retransmit retransmit enables repeated access to the same block of memory without the need to reload the initial address. an internal mirror register stores the address counter value last loaded. while ret is asserted low, the counter continues to wrap back to the value in the mirror register independent of the state of wrp . counter interrupt the counter interrupt (cntint ) is asserted low one clock cycle before an increment operation that results in the unmasked portion of the counter register being all 1s. it is deasserted by counter reset, counter load, mask reset, mask load, and mrst . counting by two when the two least significant bi ts of the mask register are 10, the counter increments by two. counting by four when the two least significant bi ts of the mask register are 00, the counter increments by four. mailbox interrupts use the upper two memory locations for message passing and permit communications between ports. table 8 on page 16 shows the interrupt operation fo r both ports. the highest memory location is the mailbox for the right port and the maximum address ? 1 is the mailbox for the left port. when one port writes to the other port?s mailbox, the int flag of the port that the mailbox belong s to is asserted low. the int flag remains asserted until the mailbox location is read by the other port. when a port reads its mailbox, the int flag is deasserted high afte r one cycle of latency with respect to the input clock of the port to which the mailbox belongs and is independent of oe . as shown in ta b l e 8 on page 16, to set the int r flag, a write operation by the left port to address 1fffff asserts int r low. a valid read of the 1fffff location by the right port resets int r high after one cycle of latency with respect to the right port?s clock. you must activate at least one byte enable to set or reset the mailbox interrupt.
