WS128K32N-17H1M

The White Electronic Designs WS128K32N-17H1M is a high-reliability 128K x 32 asynchronous SRAM multi-chip module, configured as a 4-Megabit memory solution in a rugged ceramic pin grid array (CPGA) package. Designed for mission-critical systems, it integrates multiple SRAM die to deliver a wide 32-bit data bus with a 17 ns access time class, enabling fast, deterministic read/write cycles without clock synchronization. The hermetic CPGA package ensures robust thermal performance and environmental resistance, while the module’s monolithic-like interface simplifies board layout in dense embedded designs.

Typical deployments include military avionics processors, radar and electronic warfare signal processing, precision-guided munitions, and satellite communication payloads where data integrity under extreme temperature, shock, and vibration is paramount. Industrial automation controllers and high-integrity medical imaging systems also leverage this SRAM’s fast, predictable timing. From a procurement standpoint, this device belongs to White Electronic Designs’ longstanding HiRel memory portfolio—a product line with substantial legacy in defense programs. As the manufacturer has undergone ownership transitions (now under Microchip Technology via Microsemi), the module is subject to lifetime-buy and obsolescence management considerations. Buyers should verify current production status, lead times, and authorized distribution channels to mitigate counterfeiting risks. The H1M suffix denotes a military-grade temperature range and environmental screening, making it suitable for designs requiring extended reliability documentation and traceability.
