CY7C1320AV18 Overview
The CY7C1316AV18/CY7C1318AV18/CY7C1320AV18 are 1.8V Synchronous Pipelined SRAM equipped with DDR-II architecture. The DDR-II consists of an SRAM core with advanced synchronous peripheral circuitry and a 1-bit burst counter. Addresses for Read and Write are latched on alternate rising edges of the input (K) clock.
CY7C1320AV18 Key Features
- 18-Mb density (2M x 8, 1M x 18, 512K x 36)
- 250-MHz clock for high bandwidth
- 2-Word burst for reducing address bus frequency
- Double Data Rate (DDR) interfaces (data transferred at 500 MHz) @ 250 MHz
- Two input clocks (K and K) for precise DDR timing
- SRAM uses rising edges only
- Two output clocks (C and C) account for clock skew and flight time mismatching
- Echo clocks (CQ and CQ) simplify data capture in high-speed systems
- Synchronous internally self-timed writes
- 1.8V core power supply with HSTL inputs and outputs
