CY7C1568KV18
CY7C1568KV18 is 72-Mbit DDR II+ SRAM Two-Word Burst Architecture manufactured by Cypress.
CY7C1568KV18/CY7C1570KV18
72-Mbit DDR II+ SRAM Two-Word Burst Architecture (2.5 Cycle Read Latency)
72-Mbit DDR II+ SRAM Two-Word Burst Architecture (2.5 Cycle Read Latency)
Features
- 72-Mbit density (4M × 18, 2M × 36)
- 550 MHz clock for high bandwidth
- Two-word burst for reducing address bus frequency
- Double data rate (DDR) interfaces (data transferred at
1100 MHz) at 550 MHz
- Available in 2.5 clock cycle latency
- 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
- Data valid pin (QVLD) to indicate valid data on the output
- Synchronous internally self-timed writes
- DDR II+ operates with 2.5 cycle read latency when DOFF is asserted HIGH
- Operates similar to DDR I device with 1 cycle read latency when
DOFF is asserted LOW
- Core VDD = 1.8 V ± 0.1 V; I/O VDDQ = 1.4 V to VDD[1]
- Supports both 1.5 V and 1.8 V I/O supply
- HSTL inputs and...
