24LC02BHT-I/ST

Memory IC Overview

The Microchip Technology 24LC02BHT-I/ST is a 2 Kbit (256 x 8) Electrically Erasable PROM featuring a two-wire I2C serial interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device includes an 8-byte page write buffer, hardware write-protect for the upper half-array (addresses 80h-FFh), and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead TSSOP package and rated for industrial temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array
• Integrated 8-byte page write buffer for efficient data transfer
• Schmitt trigger inputs with output slope control for signal integrity

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Parameter retention in automotive electronic modules

Memory IC Procurement Notes

Verify the specific suffix 'I/ST' confirms the Industrial temperature grade (-40°C to +85°C) and TSSOP-8 packaging. Confirm the 'H' designation indicates the Half-Array Write-Protect feature. Ensure the source documentation matches the exact part number to avoid confusion with standard 24LC02B variants lacking the WP pin functionality.

Memory IC Selection Notes

Select this component when a non-volatile memory solution requires hardware-level protection for critical configuration data stored in the upper memory addresses. It is suitable for designs needing low standby current and compatibility with standard I2C buses operating at 100 kHz or 400 kHz speeds within the specified voltage range.

Memory IC Part Context

This device belongs to the 24XX02H family of serial EEPROMs, which are distinguished by their half-array write-protect feature. Unlike the standard 24LC02B, this variant utilizes the WP pin to physically inhibit writes to addresses 80h through FFh, providing a robust mechanism against accidental data corruption in sensitive applications.
