CY7C1525AV18 Overview
QDR-II architecture consists of two separate ports: the read port and the write port 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.
CY7C1525AV18 Key Features
- Separate independent read and write data ports
- Supports concurrent transactions
- 250 MHz clock for high bandwidth
- 2-word burst on all accesses
- Double Data Rate (DDR) interfaces on both read and write ports (data transferred at 500 MHz) at 250 MHz
- Two input clocks (K and K) for precise DDR timing
- SRAM uses rising edges only
- Two input clocks for output data (C and C) to minimize clock skew and flight time mismatches
- 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
