24LC08BT-E/ST

Memory IC Overview

The Microchip Technology 24LC08BT-E/ST is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I²C protocols, supporting clock frequencies up to 400 kHz at supply voltages between 2.5V and 5.5V. The device operates within an extended temperature range of -40°C to +125°C and utilizes an 8-lead TSSOP surface-mount package.

Memory IC Feature Summary

• Supports bidirectional data transmission via a standard two-wire serial bus protocol
• Includes hardware write protection controlled by the WP pin state
• Features Schmitt trigger inputs and noise filtering for signal integrity
• Provides page write capability with a 16-byte internal buffer

Memory IC Applications

• Data logging in industrial control systems
• Configuration storage for embedded microcontrollers
• Parameter retention in automotive electronic modules
• Calibration data storage in consumer electronics

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature grade (-40°C to +125°C) and 'ST' denotes the 8-lead TSSOP package. Confirm that the voltage range is restricted to 2.5V minimum, unlike other variants in the family. Ensure compatibility with the host system's I²C pull-up requirements and voltage levels before integration.

Memory IC Selection Notes

Select this component when extended temperature operation is required alongside standard I²C connectivity. The 24LC08BT-E/ST is suitable for applications needing non-volatile storage where power consumption must be minimized during standby. Consider the 16-byte page write feature for efficient data updates. Verify that the 2.5V minimum supply voltage aligns with the target system's power rails.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA08 and 24FC08 but differs in operating voltage and speed specifications. The 24LC08B series specifically targets applications requiring reliable data retention over long periods without the ultra-low voltage support found in the AA variant or the high-speed capabilities of the FC variant.

Memory IC Replacement Considerations

Direct substitutes include other 24LC08B variants with different packages such as 24LC08BT-I/SN or 24LC08BT-E/MNY. Cross-family replacements like the 24AA08 require verification of the lower voltage threshold. Ensure any replacement maintains the same 8-pin footprint and I²C addressing scheme.
