Military-grade parallel Flash for harsh-environment firmware storage
The 5962-9323502MXA is a 2 Mbit parallel Flash memory organized as 256K x 8 bits, with a 150 ns access time and a 4.5 V supply rail. Housed in a hermetic 32-pin ceramic DIP (CDIP-32) with through-hole mounting, it is specified across the full military temperature range of -55°C to 125°C. This part is designed for non-volatile code or data storage in systems that must survive extreme thermal cycling — avionics flight computers, satellite payload controllers, missile guidance electronics, and downhole instrumentation. The parallel interface provides a deterministic, glueless read path for legacy 8-bit microcontrollers and FPGAs that lack a serial Flash controller.
Package and environment — built for sealed, high-reliability builds
The 32-CDIP hermetic package keeps moisture and contaminants out — critical for conformal-coated or potted assemblies where rework is impractical. Through-hole mounting suits point-to-point wiring in backplane or wire-wrap prototypes, and the ceramic body handles the thermal expansion mismatch of military-grade PCBs. The -55°C to 125°C temperature grade (case temperature, TC) covers cold-soak starts at altitude and sustained heat near engine bays or power stages. No derating needed across that span for the Flash array.
Sourcing posture and lifecycle
The manufacturer lists this part as Active (current lifecycle stage). It is available through independent distribution, sourced and quoted to order against an RFQ.
