Memory IC Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with existing system voltage requirements and interface protocols before procurement. Cross-reference part numbers with current manufacturer listings to avoid obsolete stock.

Memory IC Selection Notes

Select this component when a 16K capacity parallel EEPROM is required with fast 150 ns access times. The E variant provides enhanced endurance compared to standard versions. Consider the PLCC package form factor for board layout constraints. Verify that the commercial temperature range meets the operational environment specifications.

Memory IC Part Context

This part belongs to the AT28C16 series of low-power, high-performance EEPROMs. It utilizes CMOS technology for low power dissipation while maintaining fast operation. The series is designed for easy integration into microprocessor systems without external components for basic read/write operations.

Memory IC Replacement Considerations

Check for direct pin-compatible alternatives within the AT28C16 family. Verify if higher density options like the AT28C256 are suitable for future-proofing designs. Ensure any substitute maintains the same 5V supply and parallel interface characteristics.
