Memory IC datasheet and documents for 24AA02T/SN

24AA02T/SN

Memory IC Overview

The Microchip Technology 24AA02T/SN is a 2-Kbit (256 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire I2C compatible serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V with an industrial temperature range of -40°C to +85°C. The device supports a maximum clock frequency of 400 kHz at voltages above 2.5V, reducing to 100 kHz below that threshold. Key electrical characteristics include a maximum access time of 900 ns and a page write buffer capacity of 8 bytes.

Memory IC Feature Summary

Low-power CMOS technology enabling operation down to 1.7V with minimal active and standby currents
Hardware write-protect capability via the WP pin to inhibit memory writes when tied high
Integrated Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
Self-timed erase/write cycles with automatic termination

Memory IC Applications

Data logging in low-voltage embedded systems
Configuration storage for microcontrollers
Parameter retention in battery-backed circuits
Industrial sensor data archiving

Memory IC Procurement Notes

Verify the specific suffix 'SN' corresponds to the SOIC-8 package type during sourcing. Confirm the 'I' designation indicates the Industrial temperature grade (-40°C to +85°C). Ensure the ordering code matches the required tape and reel packaging format if applicable. Cross-reference the manufacturer part number with official datasheets to validate RoHS compliance status.

Memory IC Selection Notes

Select this component for applications requiring small memory footprints with I2C connectivity. It is suitable for designs needing hardware-level write protection and robust noise immunity. Consider the 1.7V minimum operating voltage for compatibility with modern low-power logic families. Verify that the 400 kHz bus speed meets system timing requirements at the intended operating voltage.

Memory IC Part Context

This device belongs to the 24XX02 family of serial EEPROMs, which also includes the 24LC02B and 24FC02 variants. While sharing similar memory organization and interface protocols, these variants differ in minimum operating voltage and maximum clock frequency specifications. The 24AA02 specifically bridges the gap between standard 2.5V devices and ultra-low voltage requirements.
