DESCRIPTION

Description

OVERVIEW

Product Overview

The 24AA256T-I/SN is an I2C serial EEPROM from Microchip's 24AA family in an SOIC-8 package. It communicates with a host controller over the I2C bus and stores configuration parameters, calibration data, and device identification that must survive power loss. Its serial interface uses few pins, making it suitable for space-constrained circuits in consumer electronics, industrial control, communication equipment, and instruments. Specific parameters such as memory size, operating voltage, and read/write speed are not provided here; refer to the original datasheet for address settings, timing requirements, and operating conditions.

APPLICATIONS

Applications

  • Used to store device configuration parameters for restoration after power-up.
  • Used to store calibration data for compensation calculations by the control system.
  • Used to record device identification and serial number information.
  • Used in communication equipment to store network parameters and operating modes.
  • Used in instruments to store user settings and measurement history.
FEATURES AND BENEFITS

Features and Benefits

  • Uses an I2C serial bus interface, requiring few pins.
  • Retains data without power, suitable for configuration and calibration storage.
  • SOIC-8 surface-mount package suits automated production.
  • Address pins allow multiple devices to share the bus.
  • Supports common operations such as page write and random read.
  • Suitable for data storage in low-power embedded systems.
ADDITIONAL DETAILS

Additional Details

When purchasing, verify memory size, operating voltage range, package type, and temperature grade, and confirm the I2C address configuration and bus speed requirements. Obtain the datasheet and lot information from the original manufacturer or authorized channels, and avoid mixing materials from different sources.

Verify product details against the manufacturer datasheet before purchase.
