24AA02T-I/MNY

Memory IC Overview

The Microchip Technology 24AA02T-I/MNY is a 2-Kbit (256 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire I²C serial interface. It operates on a single supply voltage ranging from 1.7V to 5.5V and supports clock frequencies up to 400 kHz at VCC ≥ 2.5V, or 100 kHz at VCC < 2.5V. The device utilizes low-power CMOS technology with maximum active read current of 1 mA and standby current of 1 µA in industrial temperature ranges (-40°C to +85°C). It includes an 8-byte page write buffer, hardware write-protect capability via the WP pin, and Schmitt trigger inputs for noise suppression.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication compatible with standard I²C protocols
• Features hardware write protection controlled by the dedicated WP pin state
• Includes an 8-byte page write buffer to optimize data transfer efficiency
• Provides high ESD protection exceeding 4,000V on all pins

Memory IC Applications

• Low-voltage embedded systems requiring non-volatile data storage
• Industrial control units operating within -40°C to +85°C environments
• Battery-powered devices utilizing standby current optimization
• Systems requiring hardware-level memory write protection

Memory IC Procurement Notes

Verify that the specific ordering suffix 'MNY' corresponds to the TDFN-8 package type as documented in the manufacturer's selection table. Confirm the 'I' designation indicates the Industrial temperature range (-40°C to +85°C). Ensure the application circuit accommodates the 1.7V minimum supply voltage requirement for the 24AA02 series. Cross-reference the datasheet revision DS20001709N for accurate electrical characteristics.

Memory IC Selection Notes

Select this component when a 2-Kbit EEPROM is required with a compact TDFN-8 footprint. The 24AA02 variant is appropriate for designs needing operation down to 1.7V, unlike the 24LC02B which requires a minimum of 2.5V. Consider the 400 kHz clock limit at higher voltages versus the 100 kHz limit below 2.5V. Verify that the host controller supports the I²C protocol and can manage the acknowledge polling during write cycles.

Memory IC Part Context

This part belongs to the 24XX02 family of 2-Kbit serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24LC02B and 24FC02, which share similar interfaces but differ in voltage ranges and maximum clock speeds. The 24AA02 specifically targets applications requiring lower voltage operation compared to the 24LC02B while maintaining compatibility with standard I²C bus timing requirements.
