24AA02T-I/MS

Memory IC Overview

The Microchip Technology 24AA02T-I/MS is a 2-Kbit Electrically Erasable PROM (EEPROM) organized as one block of 256 x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols. The device operates on a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies up to 400 kHz at voltages above 2.5V, or 100 kHz when VCC is between 1.7V and 2.5V. It utilizes Low-Power CMOS technology with maximum read current of 1 mA and standby current of 1 µA in industrial temperature ranges (-40°C to +85°C). The component is housed in an 8-lead MSOP surface-mount package.

Memory IC Feature Summary

• Supports bidirectional data transmission via a two-wire serial bus protocol
• Includes hardware write protection controlled by the WP pin
• Features Schmitt trigger inputs for noise suppression on SCL and SDA lines
• Provides an 8-byte page write buffer for efficient data storage operations

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention in sensor interfaces
• Small-scale data backup in low-power consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'MS' corresponds specifically to the 8-lead MSOP package type required for your PCB layout. Confirm the 'I' designation matches the industrial temperature range specifications (-40°C to +85°C) for your operational environment. Ensure compatibility with the 1.7V to 5.5V supply voltage range before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is needed for small data storage tasks. The MSOP package offers space efficiency compared to larger DIP options. Consider the 400 kHz speed limit at higher voltages if system timing requires faster bus communication. Verify that the 256-byte capacity meets application requirements without necessitating larger memory devices.

Memory IC Part Context

This part belongs to the 24XX02 family of serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24LC02B and 24FC02, which differ primarily in minimum operating voltage and maximum clock frequency capabilities. The 24AA02 variant specifically supports operation down to 1.7V, distinguishing it from parts requiring higher minimum voltages.

Memory IC Replacement Considerations

Direct replacements within the same package include other 24AA02 variants such as 24AA02T-I/MC or 24AA02T-I/SN, provided the package footprint matches. Cross-family substitutes like 24LC02B require verification of the 2.5V minimum voltage constraint.
