24AA08T-I/MNY

Memory IC Overview

The Microchip Technology 24AA08T-I/MNY is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks 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, supporting clock frequencies up to 400 kHz at voltages above 2.5V and 100 kHz below that threshold. It utilizes low-power CMOS technology with maximum active read current of 1 mA and standby current of 1 µA in industrial temperature ranges. The component is housed in an 8-lead TDFN package.

Memory IC Feature Summary

• Supports bidirectional data transmission via a two-wire serial bus protocol
• Includes hardware write-protect functionality controlled by the WP pin
• Features Schmitt trigger inputs and filter circuits for noise suppression
• Provides a 16-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 modules
• Device identification and serial number storage

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the Industrial temperature range (-40°C to +85°C) and 'MNY' denotes the 8-lead TDFN package. Confirm the 'T' indicates tape and reel packaging format. Ensure the source document explicitly lists this exact part number variant to avoid confusion with other voltage or package options within the 24AA08 family.

Memory IC Selection Notes

Select this component when a compact surface-mount EEPROM is required for low-voltage applications starting at 1.7V. It is suitable for designs needing hardware write protection and high endurance. Consider the 400 kHz speed limit and page write constraints. Verify compatibility with the host controller's I2C voltage levels and pull-up requirements before integration into the circuit design.

Memory IC Part Context

This device belongs to the 24XX08 family of 8-Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24LC08B and 24FC08 variants but differs in minimum operating voltage and maximum clock frequency specifications. The family supports multiple package types including DFN, MSOP, and PDIP, catering to diverse PCB layout requirements.

Memory IC Replacement Considerations

Direct substitutes include the 24AA08T-E/MNY for extended temperature operation or the 24LC08BT-I/MNY if the system voltage does not drop below 2.5V. Cross-reference datasheets for pinout and electrical characteristics to ensure compatibility.
