24LC128-E/SN16KVAO

Memory IC Overview

The Microchip Technology 24LC128-E/SN16KVAO is a 16K x 8 (128 Kbit) Serial Electrically Erasable PROM (EEPROM). It operates with a single supply voltage ranging from 2.5V to 5.5V and supports I2C compatible two-wire serial interfaces at clock frequencies up to 400 kHz. The device features a 64-byte page write buffer, hardware write-protect capability, and Schmitt trigger inputs for noise suppression. It is qualified under AEC-Q100 standards and offers data retention exceeding 200 years with over one million erase/write cycles.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using functional address lines.
• Includes hardware write-protect functionality controlled by the WP pin.
• Features output slope control designed to eliminate ground bounce effects.

Memory IC Applications

• Personal communications systems
• Data acquisition applications
• Low-power embedded memory storage

Memory IC Procurement Notes

Verify that the specific suffix '16KVAO' corresponds to official Microchip packaging or tape-and-reel specifications. Confirm AEC-Q100 automotive qualification status directly with the manufacturer documentation. Ensure the Extended temperature grade (-40°C to +125°C) matches system requirements. Validate RoHS compliance through current datasheet declarations.

Memory IC Selection Notes

Select this component when an I2C interface with 400 kHz speed is required for 128 Kbit non-volatile storage. Choose the Extended temperature grade for environments requiring operation up to +125°C. Consider the SOIC-8 package for surface-mount assembly needs. Verify voltage compatibility as the LC series requires a minimum of 2.5V compared to the AA series which supports 1.7V.

Memory IC Part Context

This part belongs to the 24XX128 family, which includes the 24AA128, 24LC128, and 24FC128 variants. The 24LC128 specifically denotes the low-voltage CMOS technology optimized for 2.5V to 5.5V operation. The 'E' indicates the Extended industrial temperature range, while 'SN' identifies the 8-Lead Plastic Small Outline package.

Memory IC Replacement Considerations

The 24LC128-I/SN serves as the standard Industrial temperature variant. The 24AA128-E/SN provides equivalent functionality but supports lower voltages down to 1.7V. The 24FC128-E/SN offers increased speed capabilities up to 1 MHz.
