24AA02T-I/MC

Memory IC Overview

The Microchip Technology 24AA02T-I/MC is a 2-Kbit (256 x 8) serial Electrically Erasable PROM featuring an I²C-compatible two-wire interface. It operates on a single supply voltage ranging from 1.7V to 5.5V, with a maximum clock frequency of 400 kHz at voltages above 2.5V and 100 kHz below that threshold. The device supports page writes of up to eight bytes with a maximum cycle time of 5 ms. It includes hardware write protection via the WP pin, Schmitt trigger inputs for noise suppression, and output slope control to minimize ground bounce.

Memory IC Feature Summary

• Low-power CMOS technology enabling operation down to 1.7V with minimal active and standby currents
• I²C compatible two-wire serial interface with hardware write-protect capability
• Schmitt trigger inputs and output slope control designed to suppress noise and eliminate ground bounce

Memory IC Applications

• Personal communication devices requiring low-voltage memory
• Data acquisition systems needing non-volatile storage
• Industrial applications operating within the -40°C to +85°C temperature range

Memory IC Procurement Notes

Verify the specific suffix 'MC' corresponds to the 8-lead DFN package configuration as documented in the manufacturer's selection table. Confirm the 'I' designation indicates the Industrial temperature grade (-40°C to +85°C). Ensure the ordering quantity aligns with the tape-and-reel packaging format specified for this variant. Cross-reference the datasheet revision to confirm compatibility with current design requirements.

Memory IC Selection Notes

Select this component when a 2-Kbit EEPROM is required with a 1.7V minimum operating voltage. The 400 kHz clock speed is suitable for standard I²C buses, though speeds reduce to 100 kHz if VCC falls below 2.5V. Consider the 8-byte page buffer for efficient data writing. Verify that the 8-lead DFN package fits the available PCB footprint and thermal constraints.

Memory IC Part Context

This part belongs to the 24XX02 family, which also includes the 24LC02B and 24FC02 variants. While sharing the same memory organization and interface, the 24AA02 is distinguished by its 1.7V low-voltage operation capability compared to the 2.5V minimum of the 24LC02B. It shares features with the high-speed 24FC02 but operates at lower clock frequencies.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24AA02T-I/ST, 24AA02T-I/SN, and 24AA02T-I/MNY. These alternatives share the same electrical characteristics and memory organization but differ in package type or reel specifications.
