25C080-I/P

Memory IC Overview

The Microchip Technology 25C080-I/P is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM featuring a SPI-compatible serial bus interface. It operates within a VCC range of 4.5V to 5.5V with a maximum clock frequency of 3 MHz. The device supports industrial temperature ranges from -40°C to +85°C and is housed in an 8-pin PDIP package.

Memory IC Feature Summary

• Supports block write protection for none, 1/4, 1/2, or all of the memory array
• Includes built-in power-on/off data protection circuitry and a write enable latch
• Features a hold pin to pause transmission without resetting the serial sequence

Memory IC Applications

• Microcontroller system configuration storage
• Data logging applications requiring non-volatile retention
• Parameter storage in industrial control systems

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm compatibility with the host microcontroller's SPI voltage levels, as this variant requires a minimum supply voltage of 4.5V. Check current availability status as older series components may have limited stock or be subject to obsolescence notices.

Memory IC Selection Notes

Select this component when a 5V logic interface is required for SPI communication. Ensure the application environment stays within the specified industrial temperature limits. Consider alternative variants if lower voltage operation or extended automotive temperature ranges are necessary for the design.

Memory IC Part Context

This part belongs to the 25XX080 family of 8 Kbit Serial EEPROMs. It shares architectural similarities with the 25AA080 and 25LC080 but is specifically optimized for higher voltage operation. The datasheet indicates it is not recommended for new designs, suggesting newer alternatives exist.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 25AA080A/B and 25LC080A/B.
