24LC16BT-E/SN

Memory IC Overview

The Microchip Technology 24LC16BT-E/SN is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device features an I²C compatible two-wire serial interface, Schmitt trigger inputs for noise suppression, and hardware write protection. It supports page writes of up to 16 bytes with a maximum cycle time of 5 ms. The component is housed in an 8-lead SOIC package and is rated for extended industrial temperatures from -40°C to +125°C.

Memory IC Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels, as this variant requires a minimum of 2.5V. Confirm RoHS compliance status through current datasheets or manufacturer notices before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when an I²C interface is required for small capacity non-volatile storage in harsh environments. The extended temperature range makes it suitable for automotive or industrial settings where standard commercial grades may fail. Verify that the host controller supports the necessary I²C protocol timing and acknowledge polling procedures for reliable operation.

Memory IC Part Context

This part belongs to the 24XX16 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA16 and 24FC16 devices but differs in operating voltage and speed capabilities. The 'E' designation indicates the extended temperature rating, while 'SN' specifies the 8-lead SOIC package format.

Memory IC Replacement Considerations

Direct replacements include other 24LC16B variants with different packaging such as MSOP or TDFN, provided the pinout remains compatible. Cross-referencing with 24AA16 or 24FC16 models requires careful evaluation of voltage thresholds and clock frequency limitations to ensure functional equivalence.
