24LC512T-E/SN16KVAO

Memory IC Overview

The Microchip Technology 24LC512T-E/SN16KVAO is a 512 Kbit (64K x 8) serial electrically erasable PROM featuring a two-wire I²C compatible interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device includes a 128-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. It is qualified under AEC-Q100 standards and functions reliably across an extended temperature range from -40°C to +125°C.

Memory IC Feature Summary

• Supports cascading up to eight devices on a single bus using configurable chip select pins.
• Includes a 128-byte page write buffer to optimize data transfer efficiency.
• Features hardware write protection controlled by the WP pin to prevent unintended data modification.

Memory IC Applications

• Automotive electronic systems requiring AEC-Q100 qualification
• Data acquisition systems needing non-volatile parameter storage
• Personal communication devices utilizing low-power CMOS technology

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds to the SOIC-8 package and '16KVAO' indicates specific automotive or reel packaging requirements. Confirm the 'E' designation matches the required extended temperature range (-40°C to +125°C). Ensure the I²C address configuration aligns with system constraints before procurement.

Memory IC Selection Notes

Select this component when an I²C interface is preferred over SPI for memory expansion in space-constrained designs. The 24LC512 series offers lower active current compared to parallel EEPROMs. Consider the 128-byte page size limitations during software design to avoid data overwrite issues at page boundaries.

Memory IC Part Context

This part belongs to the 24XX512 family, which also includes the 24AA512 and 24FC512 variants. While sharing similar architecture and pinouts, these variants differ in minimum operating voltage and maximum clock frequency specifications. The 24LC512 specifically targets applications requiring operation down to 2.5V.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24LC512-I/SN and 24LC512T-I/SN. Verify temperature grade compatibility when substituting Industrial grade parts for Extended grade requirements.
