ACT-F512K32N-070P7EQ

The ACT-F512K32N-070P7EQ is a high-reliability 512K x 32-bit asynchronous static RAM multichip module (MCM) manufactured by Aeroflex Circuit Technology, a supplier focused on radiation-hardened and ruggedized memory solutions for mission-critical systems. This device integrates multiple monolithic SRAM die into a single ceramic pin grid array (CPGA) package, offering a dense, board-space-efficient memory block without compromising the legacy 5V asynchronous interface. The use of CPGA packaging ensures superior thermal dissipation and mechanical robustness under shock, vibration, and wide-temperature-range operation. Typical speed grade and configuration (70 ns access time, 32-bit word width) suit systems that require fast, deterministic read/write cycles without the refresh overhead of DRAM, while retaining data integrity across extended industrial or military temperature ranges.

Designed for deployment in environments where downtime is not an option, devices from this family are commonly found in military avionics processors, radar and electronic warfare systems, satellite command and data handling modules, and weapons guidance computers. In these roles the SRAM module serves as buffer memory, scratchpad storage, or processor cache memory. Procurement teams and design engineers should note that devices carrying suffix codes indicative of MIL-STD-883 or equivalent Class Q screening (such as the “P7EQ” extension) are subject to controlled manufacturing flows, lot traceability, and additional testing, which inherently result in extended lead times and potential single-source risk. Managing lifecycle planning and verifying the part’s active status through Aeroflex or approved distributors is prudent, as high-reliability MCM products can face early obsolescence when underlying die supplies are discontinued.
