24AA52T-I/MC

Memory IC Overview

The Microchip 24AA52T-I/MC is a 2 Kbit (256 x 8) serial Electrically Erasable PROM featuring an I²C-compatible interface. It operates on a single supply voltage ranging from 1.8V to 5.5V with typical active current of 1 mA and standby current of 1 µA. The device supports a maximum clock frequency of 100 kHz when VCC is below 2.2V, and up to 400 kHz at higher voltages. It includes software write protection for the lower half of the array and hardware protection via the WP pin. Packaged in an 8-lead TDFN (2x3) format, it functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication protocol
• Provides dual write protection mechanisms including permanent software lock and external pin control
• Features Schmitt trigger inputs and output slope control for noise suppression
• Includes self-timed write cycles with automatic erase/write functionality

Memory IC Applications

• Low-power data acquisition systems requiring non-volatile storage
• Personal communication devices operating on limited power supplies
• Industrial control applications needing secure parameter retention
• Embedded systems utilizing I2C bus architectures

Memory IC Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration rather than tube. Confirm the 'I' designation matches required industrial temperature specifications. Ensure the DFN package type aligns with PCB footprint requirements. Cross-reference the datasheet revision to confirm electrical characteristics remain consistent with design intent.

Memory IC Selection Notes

Select this component when low voltage operation down to 1.8V is mandatory. Choose this part over standard variants if the 100 kHz speed limit at low voltages meets system timing constraints. Consider the TDFN package for compact surface mount designs requiring exposed pad thermal management. Evaluate the page write buffer size against application burst write requirements.

Memory IC Part Context

This device belongs to the 24AA52/24LCS52 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with other members like the 24LC52 but differs in voltage ranges and speed capabilities. The TDFN package variant offers a smaller footprint compared to traditional SOIC or PDIP options while maintaining compatible pinouts.

Memory IC Replacement Considerations

Direct substitutes include the 24AA52T-I/MNY which utilizes a TDFN package. The 24LC52 series may serve as a functional alternative if voltage requirements exceed 2.5V. Verify pin compatibility and memory organization before swapping between different manufacturer families.
