24LC32AFT-E/SN

Memory IC Overview

The Microchip Technology 24LC32AFT-E/SN is a 32 Kbit (4K x 8) serial EEPROM utilizing an I²C-compatible 2-wire interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz, with a maximum access time of 900 ns. The device features a 32-byte page write buffer and a self-timed erase/write cycle of 5 ms max. It is housed in an 8-lead MSOP package and rated for an extended industrial temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports bidirectional data transfer via a standard 2-wire serial bus protocol compatible with I²C™.
• Includes hardware write protection that inhibits writes to the upper quarter of the memory array when the WP pin is tied high.
• Features Schmitt trigger inputs on SDA and SCL pins to suppress noise spikes and eliminate ground bounce through output slope control.

Memory IC Applications

• Data acquisition systems requiring non-volatile storage
• Personal communication devices
• Low-power embedded applications

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the Automotive temperature grade (-40°C to +125°C) and the 'T' indicates tape-and-reel packaging. Confirm the 'SN' designation corresponds to the 8-lead MSOP package type. Ensure the component matches the RoHS compliance status indicated in the official datasheet DS22184A before finalizing procurement orders.

Memory IC Selection Notes

Select this part for applications requiring operation above 2.5V where the lower voltage support of the 24AA32AF variant is unnecessary. The Automotive grade ensures reliability in harsh thermal environments. Verify that the 400 kHz clock speed meets system timing requirements and that the 8-lead MSOP footprint fits the PCB layout constraints.

Memory IC Part Context

This component belongs to the 24LC32AF family of 32 Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA32AF but differs in minimum operating voltage specifications. The family utilizes a single-block memory organization and is designed for advanced low-power applications requiring robust data retention.

Memory IC Replacement Considerations

The 24LC32AT-E/SN serves as a direct replacement offering identical electrical characteristics and functionality within the same MSOP package. Both variants share the same pinout and software compatibility, allowing for interchangeability without circuit redesign.
