CY7C1521KV18
CY7C1521KV18 is 72-Mbit DDR II SRAM Four-Word Burst Architecture manufactured by Cypress.
72-Mbit DDR II SRAM Four-Word Burst Architecture
72-Mbit DDR II SRAM Four-Word Burst Architecture
Features
- 72-Mbit Density (2M × 36)
- 250 MHz Clock for High Bandwidth
- Four-word Burst for reducing Address Bus Frequency
- Double Data Rate (DDR) Interfaces (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
- Synchronous Internally Self-timed Writes
- DDR II operates with 1.5 Cycle Read Latency when DOFF is asserted HIGH
- Operates similar to DDR-I Device with 1 Cycle Read Latency when DOFF is asserted LOW
- 1.8V Core Power Supply with HSTL Inputs and Outputs
- Variable drive HSTL Output Buffers
- Expanded HSTL Output Voltage (1.4 V- VDD)
- Supports both 1.5 V and 1.8 V I/O supply
- Available in...
