24LC08B-E/ST

Memory IC Overview

The Microchip Technology 24LC08B-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 page write operations with a 16-byte buffer for efficient data transfer
• Includes hardware write protection via the WP pin to secure the entire memory array
• Features Schmitt trigger inputs and noise suppression filters for reliable operation on noisy buses

Memory IC Applications

• Data logging in industrial environments requiring extended temperature stability
• Configuration storage for embedded systems operating on single-supply voltages
• Parameter retention in automotive electronics certified under AEC-Q100 standards

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the extended temperature grade (-40°C to +125°C) and 'ST' indicates the 8-lead TSSOP package. Confirm the voltage range specification matches the 2.5V minimum requirement for the 24LC08B series, distinct from lower-voltage variants. Ensure compatibility with I2C bus timing requirements for 400 kHz operation.

Memory IC Selection Notes

Select this component when application requirements demand operation above 2.5V and extended thermal tolerance beyond standard industrial limits. The 24LC08B-E/ST is suitable for designs needing hardware write protection and robust noise immunity. Consider the 8-TSSOP footprint constraints during PCB layout planning.

Memory IC Part Context

This part belongs to the 24XX08 family of 8-Kbit serial EEPROMs manufactured by Microchip Technology. The family includes variants like the 24AA08 and 24FC08, which differ primarily in minimum operating voltage and maximum clock frequency specifications while sharing similar interface and memory organization characteristics.

Memory IC Replacement Considerations

Direct substitutes include other 24LC08B variants with different packages such as 24LC08B-I/SN or 24LC08B-I/MS, provided the temperature grade and package dimensions are acceptable for the design.
