25AA080C-I/SN

Memory IC Overview

The Microchip Technology 25AA080C-I/SN is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM accessed via a SPI-compatible serial bus. It operates within a supply voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 10 MHz. 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 SOIC 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 serial communication without resetting the sequence

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms Industrial temperature range (-40°C to +85°C) and 'SN' denotes the 8-lead SOIC package. Confirm the 'C' variant specifies the 16-byte page size, distinct from the 'D' variant's 32-byte page. Ensure RoHS compliance requirements are met for the target application environment.

Memory IC Selection Notes

Select this component when a low-voltage 1.8V operation capability is required alongside standard SPI interface compatibility. The 16-byte page size suits applications with smaller data update frequencies. Consider the automotive 'E' grade if extended temperature ranges up to +125°C are necessary instead of the industrial grade.

Memory IC Part Context

This part belongs to the 25XX080C/D family of 8K SPI Serial EEPROMs. The 'AA' prefix indicates support for 1.8V operation, while 'LC' variants require a minimum of 2.5V. The 'C' designation differentiates it from the 'D' version by specifying a 16-byte page buffer rather than 32 bytes.
