1 Mbit parallel flash in a ceramic CLCC — what this part is and where it fits
The STMicroelectronics 5962-9089901MYA is a 1 Mbit parallel flash memory from the M28F010 series, organized as 128K x 8 bits. It is a non-volatile memory with a parallel interface, supplied at 4.5 V, and housed in a 32-lead ceramic CLCC package. The device is rated for the full military temperature range of -55 to 125 °C, making it suitable for avionics, satellite, missile guidance, and downhole instrumentation where the ceramic hermetic package prevents moisture ingress and the wide temperature range guarantees operation in unheated or thermally cycling environments.
Ceramic CLCC package — sealed for high-reliability environments
The 32-lead ceramic CLCC is a hermetic surface-mount package. It protects the die against humidity and thermal shock. In avionics assemblies, it is reflow-soldered to a CTE-matched substrate; the leadless format requires visual inspection of solder joints.
Lifecycle: EOL hot — sourcing reality for the BOM line
The 5962-9089901MYA carries an EOL-hot lifecycle status, meaning the manufacturer has discontinued production and the part is in its last-time-buy window or already phased out. For a BOM line that requires this exact order code, procurement will need to source from surplus and broker channels. The part is available to quote against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. There is no official successor order code in the evidence, so a direct drop-in from the same manufacturer is not documented — each lot should be verified for date-code consistency and original packaging.
