1 Mbit parallel FLASH in a hermetic ceramic flatpack
The STMicroelectronics 5962-9089901MUA is a 1 Mbit parallel FLASH memory from the M28F010 series, organized as 128K x 8 and accessed via a parallel interface at 250 ns. It operates from a single 4.5 V supply across the full military temperature range of -55°C to 125°C, and is housed in a 32-lead ceramic flatpack (CFP) for surface-mount assembly in high-reliability environments. This part is designed for firmware storage in avionics, satellite, missile guidance, and downhole instrumentation where a hermetic, radiation-tolerant (by process) non-volatile memory is required.
Ceramic flatpack — hermetic seal for mission-critical storage
The 32-lead CFP is a hermetic, surface-mount package. It uses a standard JEDEC byte-wide pinout for direct connection to an 8-bit data bus.
Sourcing and lifecycle — what the record shows
The lifecycle record carries conflicting signals: one entry marks the part as EOL hot (end-of-life, last-time-buy window), while another lists it as Active. Given this ambiguity, the part is sourced through independent distribution channels and quoted to order against an RFQ. No official successor order code is recorded. For dual-sourcing, the 5962-9089901MYA is a pin-compatible functional alternate with identical 250 ns access time, 128K x 8 organization, and military temperature range — it shares the same M28F010 die and CFP footprint, so it drops into the same board without rewiring.
