Memory IC Procurement Notes
Verify the specific suffix ZA against official Microchip or Atmel documentation to confirm the exact package variant and temperature range. Ensure that the MIL-STD-883 compliance requirements match your project specifications. Cross-reference the manufacturer's current product status to confirm availability and obsolescence warnings before finalizing procurement plans.
Memory IC Selection Notes
Select this component when a parallel EEPROM interface is required for legacy or specific military-standard designs. Consider the 28-lead Flat Pack form factor for board space constraints in ruggedized enclosures. Evaluate the 256Kbit capacity against system data storage needs to ensure sufficient non-volatile memory for application configurations and critical data retention.
Memory IC Part Context
This part is a military version of the AT28C256 EEPROM family. The prefix 5962 indicates it is a Direct Buy microcircuit from the Defense Logistics Agency catalog. It corresponds to the AT28C256-25FM/883 commercial part number. The device represents a bridge between commercial EEPROM technology and strict military reliability standards.
Memory IC Replacement Considerations
Official cross-references include 5962-8852503XA and 5962-8852503YA. These variants share the same core functionality but differ in package type and speed grade. Verify pin compatibility and electrical characteristics before substituting.
