WS512K32N-17H1Q

The WS512K32N-17H1Q is a high-reliability 512K x 32-bit SRAM multi-chip module (MCM) manufactured by White Electronic Designs, engineered for embedded memory applications where density, speed, and ruggedness are critical. It combines multiple monolithic SRAM die within a single hermetic ceramic pin grid array (CPGA) package, delivering a 16-megabit memory array with a full 32-bit data path. Rated within the 17 ns speed class, the module provides fully static operation with no external refresh requirements, and features TTL-compatible I/O for straightforward integration into legacy and modern processor buses. The CPGA package offers superior thermal dissipation, resistance to shock and vibration, and environmental isolation, while the MCM construction minimizes board real estate and signal loading compared to discrete memory implementations.

This memory module is typically deployed in military avionics, radar and sonar processing, electronic warfare suites, satellite telemetry, and flight-critical mission computers where deterministic, low-latency data buffering and scratchpad memory are mandatory. From a procurement perspective, the part sits within a specialized high-reliability product segment, with suffix codes often denoting extended temperature range (e.g., -55°C to +125°C) and screening to MIL-STD-883 standards. As a legacy White Electronic Designs component, the WS512K32N-17H1Q carries potential end-of-life and long lead-time considerations that warrant lifecycle verification for sustained production programs. Authenticity and full traceability are essential when sourcing; acquisition through authorized channels is strongly advised to mitigate the risks of counterfeiting and to ensure conformance to the original manufacturer’s qualification data.
