WF512K32N-90H1M5A

The White Electronic Designs WF512K32N-90H1M5A is a high-reliability 512K × 32 static random-access memory (SRAM) module supplied in a ceramic pin grid array (CPGA) package. Organized as 512K words by 32 bits, the module delivers a 90 ns access-time class, providing fast, asynchronous memory performance for processor interfaces and data buffers. The CPGA housing provides robust mechanical integrity and thermal dissipation, supporting operation across demanding shock, vibration, and temperature conditions. Internal construction typically integrates multiple SRAM die to form the wide data path, and the device commonly operates from a single +5 V supply with TTL-compatible inputs and outputs, aligning with legacy and modern high-reliability bus architectures.

Typical end-use scenarios embed this module in flight-critical avionics, radar and electronic warfare signal processors, guidance computers, and rugged industrial control systems where deterministic access timing and long-term data stability are mission-critical. Procurement requires careful life cycle assessment; White Electronic Designs hi-rel memory modules are often built to order with extended lead times, and long-term availability may be subject to obsolescence risk as foundry support evolves. Sourcing through authorized channels is standard practice to maintain lot traceability and to verify screening conformance—part number suffixes may indicate compliance with military-grade requirements such as MIL-STD-883 element evaluation or proprietary high-reliability processing flows. Validating certificates of conformance and authenticating pedigree are essential steps for program-level qualification and sustained production.
