IFXCY7C1565KV18-400BZXI
Overview
The CY7C1565KV18-400BZXI is a high-performance 72Mbit Quad Data Rate II+ (QDR II+) SRAM designed for applications requiring high bandwidth and low latency. It features separate independent read and write ports that operate concurrently at a 400 MHz clock frequency, utilizing a Double Data Rate (DDR) interface to maximize throughput. This memory is optimized for high-speed networking and data processing systems where simultaneous data movement is critical.
Why Choose This Part
The QDR II+ architecture provides full data coherency and eliminates bus contention by using separate read and write ports. Operating at 400 MHz with a 2.5-clock cycle latency, it offers superior performance over standard SRAM in random access patterns. Additionally, the integrated Phase-Locked Loop (PLL) ensures precise timing for high-speed DDR data transfers.
Applications
Key Specifications
Getting Started
Designers should integrate this SRAM with high-performance FPGAs or ASICs that support the HSTL (High-Speed Transceiver Logic) interface. Ensure precise PCB trace length matching for the K/K differential clock inputs and the CQ/CQ echo clocks to maintain timing margins at 400 MHz. The device requires a core voltage supply between 1.7V and 1.9V and follows the 165-FBGA footprint.
