24LC32AFT-I/OT

Memory IC Overview

The Microchip Technology 24LC32AFT-I/OT is a 32 Kbit Electrically Erasable PROM organized as a single block of 4K x 8-bit memory. It features a 2-wire serial interface compatible with I²C™, supporting clock frequencies up to 400 kHz for VCC ≥ 2.5V. The device operates on a single supply voltage ranging from 2.5V to 5.5V. It includes hardware write-protect functionality for the upper quarter of the array and supports page writes of up to 32 bytes. The component is housed in an 8-lead MSOP package and is rated for industrial temperature operation from -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication via SDA and SCL pins
• Includes hardware write-protect capability for the upper quarter of the memory array
• Features Schmitt trigger inputs for noise suppression and output slope control
• Provides self-timed erase/write cycles with acknowledge polling support

Memory IC Applications

• Personal communications devices requiring low-power non-volatile storage
• Data acquisition systems needing reliable parameter retention
• Embedded controllers utilizing I²C bus architecture
• Industrial equipment operating within specified temperature ranges

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm the specific revision level against the manufacturer's datasheet to ensure compatibility with existing designs. Check for any product change notifications regarding assembly sites or material composition updates prior to finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 32 Kbit EEPROM with I²C interface is required for industrial environments. Ensure the system voltage remains above 2.5V to maintain 400 kHz clock compatibility. Consider the MSOP package dimensions for PCB layout constraints. Verify that the application does not require write protection for the entire array, as this device only protects the upper quarter.

Memory IC Part Context

This part belongs to the 24LC32AF family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA32AF series but differs in minimum operating voltage requirements. The family is designed for low-power applications and offers high endurance with data retention capabilities exceeding standard industry expectations for non-volatile memory solutions.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24LC32AF-E/MS and 24LC32AF-I/ST. Verify pinout compatibility and voltage specifications before substitution.
