Write Cycle Descriptions
The write cycle description table for CY7C21701KV18 follows.
Notes
Document Number: 001-57344 Rev. *A
Write Cycle:
Load address; wait one cycle;
input write data on consecutive K and K rising edges.
Read Cycle: (2.5 cycle Latency)
Load address; wait two and half cycles;
read data on consecutive K and K rising edges.
NOP: No Operation
Standby: Clock Stopped
4. X = “Don’t Care,” H = Logic HIGH, L = Logic LOW, ↑ represents rising edge.
5. Device powers up deselected with the outputs in a tri-state condition.
6. “A” represents address location latched by the devices when transaction was initiated. A + 1 represents the address sequence in the burst.
7. “t” represents the cycle at which a read/write operation is started. t + 1 and t + 2 are the first and second clock cycles succeeding the “t” clock cycle.
8. Data inputs are registered at K and K rising edges. Data outputs are also delivered on K and K rising edges.
9. Ensure that when clock is stopped K = K and C = C = HIGH. This is not essential, but permits most rapid restart by overcoming transmission line charging symmetrically.
10. Is based on a write cycle that was initiated in accordance with the
BWS
of a write cycle, as long as the setup and hold requirements are achieved.
