CY7C131-55JC – CYPRESS SEMICONDUCTOR CORP

The CY7C131-55JC is a high-speed, dual-port static RAM device manufactured by Cypress Semiconductor, fabricated using a submicron CMOS process. Specified for operation at a maximum access time of 55 ns, this device provides asynchronous, simultaneous access to a shared memory array from two independent ports. Organized as 1024 x 8 bits, it features separate data input/output pins for each port, eliminating the need for external arbitration logic in many applications. The device operates from a single 5V power supply and offers low power consumption. Housed in a 52-pin Plastic Leaded Chip Carrier (PLCC) package, the CY7C131-55JC is suitable for applications requiring high-bandwidth data transfer between processors or systems, such as digital signal processing, image processing, and communication buffers. The 2004 date code suggests a specific fabrication process and potential errata should be considered in legacy designs.
