24LC32AF-E/P

Memory IC Overview

The Microchip Technology 24LC32AF-E/P is a 32 Kbit (4K x 8) non-volatile EEPROM featuring an I²C-compatible 2-wire serial interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz, with an access time of 900 ns. The device utilizes an 8-lead PDIP package and functions across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Hardware write-protect capability for the upper quarter of the memory array via the WP pin
• Supports page write operations with a 32-byte buffer to enhance bus throughput
• Schmitt trigger inputs provide noise suppression on SDA and SCL lines

Memory IC Applications

• Personal communication devices requiring low-power data storage
• Data acquisition systems needing non-volatile parameter retention
• Embedded controllers managing configuration settings via I²C

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Automotive temperature grade (-40°C to +125°C), while datasheet specifications list Industrial grade (-40°C to +85°C). Confirm the 'P' suffix indicates the 8-lead PDIP package. Ensure compatibility with 2.5V to 5.5V supply rails before procurement.

Memory IC Selection Notes

Select this component for applications requiring hardware write protection for specific memory segments. The 8-pin PDIP format suits through-hole prototyping or manufacturing. Verify that the 400 kHz I²C speed meets system timing requirements and that the 32-byte page buffer aligns with write efficiency needs.

Memory IC Part Context

This part belongs to the 24AA32AF/24LC32AF family of 32 Kbit Serial EEPROMs. The 24LC32AF variant specifically requires a minimum operating voltage of 2.5V, distinguishing it from the 24AA32AF which supports operation down to 1.7V. Both share identical interface protocols and physical packaging options.

Memory IC Replacement Considerations

The 24LC32A-I/P serves as a functional substitute within the same product line, offering identical electrical characteristics but rated for the Industrial temperature range rather than the Automotive grade.
