CY7C1143V18 Description
QDR-II+ architecture consists of two separate ports to access the memory array. The read port has dedicated data outputs to support read operations and the write port has dedicated data inputs to support write operations. QDR-II+ architecture has separate data inputs and data outputs to pletely eliminate the need to “turn-around” the data bus required with mon IO devices.
CY7C1143V18 Key Features
- Supports concurrent transactions
- 300 MHz to 375 MHz clock for high bandwidth
- 4-Word Burst for reducing address bus frequency
- Double Data Rate (DDR) interfaces on both read and write ports (data transferred at 750 MHz) at 375 MHz
- Read latency of 2.0 clock cycles
- Two input clocks (K and K) for precise DDR timing
- SRAM uses rising edges only
- Echo clocks (CQ and CQ) simplify data capture in high speed systems
- Single multiplexed address input bus latches address inputs for both read and write ports
- Separate Port Selects for depth expansion
