Product Summary

The CY7C1463AV33-133AXI is a 3.3V, 2M x 18 Synchronous Flow-Through Burst SRAM designed specifically to support unlimited true back-to-back read and write operations without the insertion of wait states. The CY7C1463AV33-133AXI is equipped with the advanced NoBL logic required to enable consecutive read and write operations with data being transferred on every clock cycle. This feature dramatically improves the throughput of data through the SRAM, especially in systems that require frequent write-read transitions.

Parametrics
