24LC08BT-I/MS

Memory IC Overview

The Microchip Technology 24LC08BT-I/MS 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 for supply voltages between 2.5V and 5.5V. The device operates within an industrial temperature range of -40°C to +85°C and utilizes low-power CMOS technology. It includes hardware write protection via the WP pin and supports page writes of up to 16 bytes.

Memory IC Feature Summary

• Supports bidirectional data transmission over a standard two-wire serial bus using SDA and SCL lines.
• Includes Schmitt trigger inputs on data and clock pins to suppress noise spikes and ensure stable operation.
• Features a hardware write-protect pin that inhibits all write operations when tied to VCC while allowing read access.
• Provides output slope control to minimize ground bounce during signal transitions.

Memory IC Applications

• Non-volatile data storage in embedded systems requiring persistent configuration parameters.
• Industrial control devices needing reliable memory under varying electrical noise conditions.
• Consumer electronics utilizing low-voltage power supplies for compact circuit designs.

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm voltage compatibility with the target system, as this variant requires a minimum of 2.5V. Check for RoHS compliance status if environmental regulations apply. Ensure the design accounts for the specific pinout of the MSOP package during PCB layout.

Memory IC Selection Notes

Select this component when an 8-Kbit capacity is sufficient for application requirements. Choose this part over variants like the 24AA08 if the system operates exclusively at or above 2.5V. Consider the MSOP package dimensions against available board space. Verify that the host controller supports the I²C protocol timing specifications defined for 400 kHz operation.

Memory IC Part Context

This device belongs to the 24XX08 family of serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA08 and 24FC08 but differs in operating voltage ranges and maximum clock speeds. The 'I' designation indicates the industrial temperature rating, while 'MS' specifies the surface-mount MSOP package.

Memory IC Replacement Considerations

Direct replacements include other 24LC08B variants in different packages such as SOIC or TSSOP, provided pinouts are compatible. Cross-referencing with 24AA08 models is possible only if the supply voltage meets the 2.5V minimum requirement. Verify that any substitute maintains the same I²C addressing scheme and page buffer size.
