WF512K32N-70H1M5

The White Electronic Designs WF512K32N-70H1M5 is a high-reliability 512K x 32-bit asynchronous static RAM module, organized as a dense 16-Mbit memory array and rated for a 70 ns access time in a ceramic pin grid array (CPGA) package. Typical features of this SRAM module family include a common I/O data path, fully static operation requiring no external clocks or refresh, and single 5 V supply operation with low-power standby modes that help reduce thermal load in sealed enclosures. The CPGA package delivers robust shock and vibration resistance alongside a wide operating temperature range, while the 32-bit word width and fast access speed support zero‑wait‑state operation in high‑performance processors and digital signal processing chains.

These HiRel SRAM modules are routinely embedded in mission-critical military avionics, radar and electronic warfare processors, space‑qualified data handling units, and ruggedized industrial controls where deterministic access and data retention are paramount. The part’s “H” class designation indicates a controlled manufacturing baseline and screening flows consistent with MIL‑STD‑883 requirements, enabling operation across the full ‑55 °C to +125 °C military temperature range and long service life in demanding environments. From a procurement perspective, the WF512K32N-70H1M5 is a legacy White Electronic Designs product; supply is inherently constrained, and obsolescence risk is elevated. Engineering and purchasing teams should validate part authenticity and chain of custody through authorized, traceable sources, and plan for extended lead times or initiate last‑time‑buy actions to secure long‑term program support.
