25LC080C-I/P

Overview

The Microchip Technology 25LC080C-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 2.5V to 5.5V and supports a maximum clock frequency of 10 MHz at 4.5V ≤ VCC ≤ 5.5V. The device features a 16-byte page size, self-timed erase/write cycles with a maximum duration of 5 ms, and industrial temperature coverage from -40°C to +85°C. It is housed in an 8-lead PDIP package.

Feature Summary

• Supports high-speed SPI communication with up to 10 MHz clock frequency
• Includes programmable block write protection for array segments
• Features built-in power-on/off data protection and write enable latch
• Provides hold functionality to pause serial transmission without resetting the sequence

Applications

• Microcontroller system configuration storage
• Calibration parameter persistence
• Data logging and event recording
• Embedded software version tracking

Procurement Notes

Verify the specific suffix 'I' confirms industrial temperature range (-40°C to +85°C) and 'P' denotes the 8-lead PDIP package. Confirm the 'C' variant specifies the 16-byte page size rather than the 32-byte page size found in 'D' variants. Ensure RoHS compliance requirements are met by checking for Pb-free markings on the component body or packaging documentation.

Selection Notes

Select this component when a non-volatile memory solution requires SPI interface compatibility with standard microcontrollers. It is suitable for applications needing moderate data retention endurance exceeding one million erase/write cycles. Consider the 16-byte page write limitation for write-heavy workloads and ensure the operating voltage aligns with the 2.5V to 5.5V supply range.

Part Context

This part belongs to the 25LC080C/D family of 8K SPI Bus Serial EEPROMs. The 'LC' designation indicates a 2.5V minimum operating voltage, distinguishing it from the 1.8V minimum 'AA' series. The 'C' suffix identifies the 16-byte page architecture, whereas 'D' variants offer 32-byte pages. This family provides a cost-effective, low-power memory option for embedded systems requiring reliable data storage.

Replacement Considerations

25LC080D-I/P offers identical electrical characteristics but utilizes a 32-byte page size instead of 16 bytes. 25AA080C-I/P provides similar functionality but supports a lower minimum voltage of 1.8V. Verify pinout compatibility and page size requirements before substituting.
