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. 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.
