24LC08BT-I/ST

Memory IC Overview

The Microchip Technology 24LC08BT-I/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 when VCC is between 2.5V and 5.5V. The device operates within a supply voltage range of 2.5V to 5.5V and supports industrial temperature ranges from -40°C to +85°C. Key electrical characteristics include a maximum access time of 900 ns, a page write time of 5 ms, and low standby current consumption.

Memory IC Feature Summary

• Supports bidirectional data transmission via a two-wire serial interface compatible with standard I2C protocols.
• Includes hardware write-protect functionality controlled by the WP pin to inhibit write operations when tied to VCC.
• Features Schmitt trigger inputs and filter circuits on SDA and SCL pins for noise suppression.
• Provides output slope control designed to eliminate ground bounce during signal transitions.

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Parameter retention in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type, specifically TSSOP for this part number. Confirm the temperature grade 'I' aligns with the intended operating environment of -40°C to +85°C. Ensure the voltage specification meets system requirements, as this variant operates down to 2.5V rather than 1.7V. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Memory IC Selection Notes

Select this component when an 8-Kbit non-volatile memory solution is required with I2C connectivity. It is suitable for applications needing hardware write protection and robust noise immunity through Schmitt triggers. Consider the 8-TSSOP package for surface-mount designs requiring a compact footprint. Verify that the 400 kHz clock speed suffices for the system's bus throughput needs.

Memory IC Part Context

This device belongs to the 24LC08B series of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA08 and 24FC08 devices but differs in minimum operating voltage and maximum clock frequency specifications. The 24LC08B series is distinct from higher-capacity variants like the 24LC16 or 24LC32.

Memory IC Replacement Considerations
