What this 1Mbit NOR Flash is and where it fits
The STMicroelectronics 5962-9089904MUA is a 1Mbit parallel NOR Flash memory from the M28F010 series, organized as 128K x 8 bits. It uses a 4.5 V supply and presents a 120 ns access time on a parallel interface. The part is packaged in a 32-lead ceramic flatpack (CFlatPack) for surface-mount assembly, and it is specified across the full military temperature range of -55°C to 125°C. This combination of hermetic ceramic package, wide temperature grade, and NOR Flash non-volatility makes it a fit for avionics, satellite, missile guidance, and downhole instrumentation where code storage or parameter logging must survive extreme thermal cycling and radiation-soft environments.
Package and mounting — ceramic flatpack realities
The 32-lead CFlatPack is a hermetic ceramic package with gull-wing leads for surface mounting. The leads are solderable but require a reflow profile compatible with ceramic.
