Datasheet Summary
CY7C1618KV18/CY7C1620KV18
144-Mbit DDR II SRAM Two-Word Burst Architecture
144-Mbit DDR II SRAM Two-Word Burst Architecture
Features
- 144-Mbit density (8M × 18, 4M × 36)
- 333 MHz clock for high bandwidth
- Two-word burst for reducing address bus frequency
- Double data rate (DDR) interfaces (data transferred at
666 MHz) at 333 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
- Synchronous internally self-timed writes
- DDR II operates with 1.5-cycle read latency when DOFF is asserted high
