ACT-S512K32N-017P7EQ

The ACT-S512K32N-017P7EQ from Aeroflex Circuit Technology is a high-reliability cache SRAM multi-chip module (MCM) organized as 512K x 32 bits. Fabricated with CMOS technology, it delivers a 17 ns access time and is housed in a 66-pin ceramic pin grid array (CPGA) package, providing robust mechanical integrity and efficient heat dissipation for harsh operating conditions. The module integrates multiple memory die within a hermetically sealed cavity to achieve high density while conserving board space and preserving signal integrity—characteristics essential for compact, high-speed digital systems.

Typical applications include processor cache, data buffers, and scratchpad memory in military and aerospace embedded computing systems such as radar signal processors, flight control computers, and electronic warfare suites. The HiRel MCM construction indicates suitability for extended temperature ranges and compliance with demanding screening standards. As a specialized memory component from a defense-oriented manufacturer, this part may carry extended lead times and is subject to obsolescence management considerations; procurement should emphasize traceability, authorized sourcing, and export control compliance. The module’s straightforward SRAM interface supports integration with a wide range of legacy and modern microprocessors and DSPs in long-life, mission-critical systems.
