Memory IC datasheet and documents for 24AA256T-I/SN

24AA256T-I/SN

Memory IC Overview

The Microchip Technology 24AA256T-I/SN is a 256-Kbit (32K x 8) Serial Electrically Erasable PROM (EEPROM). It operates on a single supply voltage ranging from 1.7V to 5.5V and supports a maximum clock frequency of 400 kHz via a two-wire I²C compatible interface. The device features a 64-byte page write buffer, hardware write protection, and Schmitt trigger inputs for noise suppression. It is rated for industrial temperature ranges (-40°C to +85°C) and housed in an 8-lead SOIC package.

Memory IC Feature Summary

Supports cascading up to eight devices on the same bus using functional address lines A0, A1, and A2.
Includes hardware write protection controlled by the WP pin to inhibit array writes when tied high.
Features output slope control designed to eliminate ground bounce during operation.

Memory IC Applications

Personal communications systems requiring low-power non-volatile storage
Data acquisition applications needing reliable parameter retention
Industrial control systems utilizing I²C serial interfaces

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds specifically to the 8-lead Small Outline Integrated Circuit (SOIC) package configuration. Confirm the 'I' designation indicates compliance with the Industrial temperature range specifications (-40°C to +85°C). Ensure the component matches the exact part number to guarantee correct voltage and timing characteristics.

Memory IC Selection Notes

Select this component for designs requiring broad voltage compatibility down to 1.7V. It is suitable for applications needing multiple devices on a single bus due to its three configurable chip select pins. Consider the 64-byte page write capability for efficient data writing operations compared to byte-write-only alternatives.

Memory IC Part Context

This component belongs to the 24AA256/24LC256/24FC256 family of 256-Kbit Serial EEPROMs manufactured by Microchip Technology. While sharing core architecture, the 24AA256 variant is distinguished by its ability to operate at voltages as low as 1.7V, unlike the 24LC256 which requires a minimum of 2.5V.
