Memory IC Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type, speed grade, and temperature range. Ensure compatibility with system voltage requirements and interface signals before integration. Cross-reference datasheet revision dates for accurate electrical specifications.

Memory IC Selection Notes

Select this component when a 64K capacity with 150 ns speed is required in a PLCC-32 package. Consider the E suffix for enhanced endurance compared to standard variants. Verify that the industrial temperature range meets environmental constraints and that the 5V supply aligns with system power rails.

Memory IC Part Context

This part belongs to the AT28C64 family of parallel EEPROMs. It provides nonvolatile storage with static RAM-like access. The 'E' designation indicates high endurance options. The 'JI' suffix specifies the industrial temperature range and PLCC-32 package configuration within the product line.

Memory IC Replacement Considerations

Compatible substitutes include other AT28C64 variants with matching speed and package. Verify pinout compatibility and electrical parameters such as VCC tolerance and current consumption before substitution.
