24FC08T-I/ST

Memory IC Overview

The Microchip Technology 24FC08T-I/ST is an 8-Kbit (1K x 8) serial EEPROM featuring a two-wire I²C compatible interface. It supports clock frequencies up to 1 MHz and operates within a supply voltage range of 1.7V to 5.5V. The device provides a maximum access time of 450 ns and includes a 16-byte page write buffer with a maximum write cycle time of 5 ms. It is housed in an 8-lead TSSOP package and is rated for industrial operating temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed I²C communication with clock frequencies up to 1 MHz
• Includes a 16-byte page write buffer to optimize data writing efficiency
• Features hardware write protection via the WP pin to prevent unauthorized memory modifications
• Incorporates Schmitt trigger inputs and noise filtering for reliable operation on noisy buses

Memory IC Applications

• Personal communications devices requiring low-power non-volatile storage
• Data acquisition systems needing frequent parameter updates
• Industrial control applications utilizing I²C bus architectures
• Embedded systems requiring hardware-level write protection

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type, as the base part number covers multiple variants. Confirm the presence of the 'T' suffix indicates tape and reel packaging if bulk handling is required. Ensure the 'I' designation aligns with the intended industrial temperature range specifications for the application environment.

Memory IC Selection Notes

Select this component when a 1 MHz I²C interface speed is necessary, distinguishing it from slower 400 kHz variants like the 24LC08B. Choose this part over the 24AA08 if operation below 2.5V is required, as the 24FC08 supports voltages down to 1.7V. Consider the 8-TSSOP package dimensions for PCB layout constraints compared to other available footprints in the series.

Memory IC Part Context

This device belongs to the 24XX08 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA08 and 24LC08B but offers distinct electrical characteristics regarding voltage range and clock speed. The family utilizes a common I²C protocol and pinout structure across various package options including SOIC, MSOP, and DFN.
