Memory IC datasheet and documents for 24AA32AF-I/SN

24AA32AF-I/SN

Memory IC Overview

The Microchip Technology 24AA32AF-I/SN 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™ protocols, supporting clock frequencies up to 400 kHz for VCC ≥ 2.5V and 100 kHz for lower voltages. The device operates on a single supply ranging from 1.7V to 5.5V, with maximum active read current of 400 μA and standby current of 1 μA. It includes hardware write-protect functionality for the upper quarter of the array (addresses C00h-FFFh) via the WP pin.

Memory IC Feature Summary

Hardware write-protect capability for the upper quarter of the memory array
Supports cascading up to eight devices on the same bus using functional address pins
Includes Schmitt trigger inputs for enhanced noise suppression

Memory IC Applications

Personal communications systems requiring low-power non-volatile storage
Data acquisition applications needing reliable parameter retention
Embedded systems utilizing I²C bus architectures

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm the specific voltage range requirements align with the Industrial grade specifications. Ensure compatibility with the host controller's I²C timing constraints before finalizing procurement.

Memory IC Selection Notes

Select this component when a 32 Kbit EEPROM with hardware write protection is required. It is suitable for designs operating between 1.7V and 5.5V. Consider the SOIC-8 package availability and ensure the application supports the 2-wire serial protocol limitations.

Memory IC Part Context

This part belongs to the 24AA32AF/24LC32AF family of serial EEPROMs. It shares architectural similarities with other members but is distinguished by its specific voltage range and industrial temperature rating. The 'I' suffix denotes the Industrial temperature range specification.
