24LC32AF-E/P EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24LC32AF-E/P is a 32Kbit EEPROM memory integrated circuit manufactured by Microchip Technology, designed for non-volatile data storage applications requiring I2C serial communication. This device operates at 400 kHz clock frequency with a 900 ns access time, supporting supply voltages from 2.5V to 5.5V across an extended temperature range of -40°C to 125°C. The component is housed in an 8-PDIP through-hole package and maintains Active product status with ROHS3 compliance. Substitute parts are identified when all critical electrical and mechanical parameters remain identical, ensuring direct functional equivalence without circuit redesign.
