The CY7C028V-15AXI is a 1-Mbit (64K x 16/18) asynchronous dual-port static RAM manufactured by Cypress Semiconductor, designed for shared-memory architectures requiring simultaneous access from multiple processors or buses. Operating from a single 3.3 V supply, this device offers a 15 ns access time and symmetrical independent ports with separate control, address, and I/O pins, enabling fully asynchronous operations without wait states in many systems. The memory array can be configured as either 64K × 16 or 64K × 18 (with parity) via input pins, and each port supports byte-write capability. Housed in a 100-pin TQFP package, the CY7C028V-15AXI is specified for industrial temperature range (–40°C to +85°C), making it suitable for embedded systems deployed in harsh environments.
Typical applications include industrial process control, test and measurement instrumentation, avionics systems, and defense electronics where dual-port RAMs serve as high-speed interprocessor communication buffers, video frame buffers, or data bridges between FPGAs, DSPs, and microcontrollers. The device’s asynchronous nature and fast access time allow it to simplify timing in legacy system upgrades and new designs that require deterministic shared memory access. Procurement engineers should note that Cypress (now part of Infineon Technologies) has a history of long-lifetime support for memory products, but it is advisable to verify current lifecycle status and availability for long-term programs, especially given ongoing semiconductor supply chain dynamics. The industrial-grade ‘XI’ suffix ensures operation over extended temperature ranges without the cost premium of full military-qualified components.
