25LC080D-I/P

Overview

The Microchip Technology 25LC080D-I/P is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM accessed via a SPI-compatible serial bus. It operates within a voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 10 MHz. The device features a 32-byte page size, self-timed erase/write cycles with a maximum duration of 5 ms, and industrial temperature ratings from -40°C to +85°C. It is housed in an 8-lead PDIP package.

Feature Summary

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

Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage

Procurement Notes

Verify the specific suffix 'I' confirms the Industrial temperature range (-40°C to +85°C) and 'P' denotes the 8-lead PDIP package. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when a 32-byte page size is required instead of the 16-byte variant found in the 'C' series. Ensure the application environment remains within the specified industrial temperature limits and that the supply voltage stays between 2.5 V and 5.5 V for proper operation.

Part Context

This part belongs to the 25XX080C/D family of 8 Kbit SPI Serial EEPROMs. It shares architectural similarities with the 25LC080C but differs in page organization. The 'D' designation specifically indicates the 32-byte page capability, distinguishing it from other memory organizations in the product line.

Replacement Considerations

The 25LC080A-I/P is a documented substitute offering identical electrical characteristics and functionality within the same package type.
