Datasheet Summary
CY7C1319KV18/CY7C1321KV18
18-Mbit DDR II SRAM Four-Word Burst Architecture
18-Mbit DDR II SRAM Four-Word Burst Architecture
Features
- 18-Mbit density (1M × 18, 512K × 36)
- 333-MHz clock for high bandwidth
- Four-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...
