24LC128T-E/SN16KVAO

Memory IC Overview

The Microchip Technology 24LC128T-E/SN16KVAO is a 128 Kbit (16K x 8) Serial Electrically Erasable PROM (EEPROM). It operates on a single supply voltage ranging from 2.5V to 5.5V and features an I2C compatible two-wire serial interface with a maximum clock frequency of 400 kHz. The device supports page write operations with a 64-byte buffer and includes hardware write protection via the WP pin. It is qualified under AEC-Q100 standards for automotive applications, ensuring reliability across an extended temperature range of -40°C to +125°C.

Memory IC Feature Summary

• AEC-Q100 qualified for automotive grade reliability
• Hardware write-protect capability via dedicated pin
• Schmitt trigger inputs for enhanced noise suppression
• Supports cascading up to eight devices on a single bus

Memory IC Applications

• Automotive data acquisition systems
• Personal communications equipment
• Low-power embedded memory storage

Memory IC Procurement Notes

Verify the specific suffix 'SN16KVAO' against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure the ordering code matches the required automotive qualification and temperature range. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement.

Memory IC Selection Notes

Select this component when automotive-grade durability and extended temperature operation are required. The 2.5V minimum supply voltage distinguishes it from lower-voltage variants. Verify that the system design accommodates the 400 kHz I2C speed limit and utilizes the hardware write-protect feature if data integrity during power fluctuations is critical.

Memory IC Part Context

This part belongs to the 24XX128 family, which includes the 24AA128 and 24FC128. While sharing similar architecture, the 24LC128 variant specifically requires a minimum operating voltage of 2.5V, unlike the 1.7V capable 24AA128. The 'E' designation indicates the extended industrial temperature range suitable for harsh environments.

Memory IC Replacement Considerations

Direct replacements within the same family include the 24LC128-I/SN for industrial temperature ranges. For automotive applications requiring identical specifications, verify availability of other 24LC128T-E/SN variants. Cross-compatibility with 24AA128 or 24FC128 requires checking voltage and speed constraints.
