CYRS1543AV18, CYRS1545AV18: 72-Mbit QDR® II+ SRAM Four-Word Burst Architecture with RadStop™ Technology
72-Mbit QDR® II+ SRAM Four-Word Burst Architecture with RadStop™ Technology
- Separate independent read and write data ports
- Supports concurrent transactions
- 250 MHz clock for high bandwidth
- Four-word burst for reducing address bus frequency
- Double data rate (DDR) interfaces on both read and write ports at 250 MHz (data transferred at 500 MHz)
- 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 read and write ports
- Separate port selects for depth expansion
