ACT-F128K32N-070P7Q

The ACT-F128K32N-070P7Q is a high-reliability 128K x 32 static RAM multichip module (MCM) manufactured by Aeroflex Circuit Technology, designed for critical systems requiring ruggedized memory with a 70 ns access time. This device integrates multiple die into a single hermetically sealed ceramic pin grid array (CPGA) package, delivering a 4-megabit SRAM solution with a 32-bit data bus width. The ceramic PGA construction provides superior thermal dissipation, mechanical resilience, and resistance to moisture and contamination, making it suitable for extended temperature operation and harsh environments. The MCM architecture in this family reduces board footprint and interconnect parasitics compared to discrete implementations, while maintaining full asynchronous SRAM functionality with low standby current draw.

Typical applications span mission-critical avionics, satellite payloads, military radar signal processing, and guidance systems where deterministic access timing and immunity to single-event upsets are essential. The part is commonly deployed as local cache, data buffer, or scratchpad memory in flight computers, weapons control units, and telemetry subsystems. Procurement engineers should note that Aeroflex’s semiconductor lines were acquired by Cobham and later divested, creating supply-chain discontinuities and long lead times for legacy high-reliability modules. Sourcing through authorized distribution with full traceability and lot-level conformance documentation is necessary to avoid counterfeit or non-conforming devices. The hermetic CPGA package and screening options inherent to the ACT-F128K32N family warrant confirmation that the specific suffix code (P7Q) aligns with the required MIL-STD-883 or equivalent quality level for the intended application.
