24LC08B-E/SN16KVAO

Memory IC Overview

The Microchip Technology 24LC08B-E/SN16KVAO is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It operates with a single supply voltage ranging from 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz via a 2-Wire Serial Interface compatible with I2C protocols. The device features a hardware write-protect pin, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce. It is qualified under the AEC-Q100 automotive standard and offers data retention exceeding 200 years with over one million erase/write cycles endurance.

Memory IC Feature Summary

• Hardware Write-Protect: Enables complete array protection when the WP pin is tied to VCC, inhibiting all write operations while allowing reads.
• Automotive Qualification: Meets AEC-Q100 standards for reliability in demanding automotive environments.
• Noise Suppression: Incorporates Schmitt Trigger inputs on SDA and SCL lines to filter noise spikes and ensure stable communication.
• Page Write Capability: Includes a 16-byte page write buffer to optimize data transfer efficiency during write cycles.

Memory IC Applications

• Automotive electronic systems requiring reliable non-volatile data storage
• Industrial control units needing robust memory for configuration parameters
• Consumer electronics utilizing I2C interfaces for low-power data logging

Memory IC Procurement Notes

Verify that the specific suffix 'SN16KVAO' corresponds to the 8-Lead SOIC package and Extended Temperature grade as documented in official Microchip datasheets. Confirm AEC-Q100 qualification status for the exact part number variant before integration into automotive designs. Ensure compatibility with 2.5V to 5.5V supply rails and 400 kHz bus speeds.

Memory IC Selection Notes

Select this component for applications requiring extended temperature operation up to +125°C and automotive-grade reliability. The 8-Lead SOIC package provides a suitable footprint for surface-mount assembly. Consider the 400 kHz speed limit and 2.5V minimum operating voltage when designing power and communication circuits.

Memory IC Part Context

This part belongs to the 24LC08B series of 8-Kbit serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA08 and 24FC08 devices but is distinguished by its 2.5V minimum operating voltage and 400 kHz maximum clock frequency, unlike the 1 MHz capability of the 24FC08 or the 1.7V support of the 24AA08.

Memory IC Replacement Considerations

Direct substitutes include other 24LC08B variants in different packages such as 24LC08BT-I/MS or 24LC08BHT-E/OT, provided the package type and temperature grade match the design requirements. Cross-reference with 24AA08 or 24FC08 only if voltage and speed constraints allow.
