24FC08T-I/SN

Memory IC Overview

The Microchip Technology 24FC08T-I/SN 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 1 MHz across a supply voltage range of 1.7V to 5.5V. The device utilizes low-power CMOS technology, drawing a maximum standby current of 3 µA and operating current of 1 mA. It includes a 16-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. The component is housed in an 8-lead SOIC package and operates within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed I²C communication with clock frequencies reaching 1 MHz
• Includes a 16-byte page write buffer to optimize data writing efficiency
• Features hardware write protection controlled by the WP pin to prevent unauthorized modifications
• Incorporates Schmitt trigger inputs and output slope control for enhanced signal integrity

Memory IC Applications

• Personal communications devices requiring non-volatile data storage
• Data acquisition systems needing reliable parameter retention
• Industrial control applications utilizing I²C bus architectures

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) and 'SN' indicates the 8-lead SOIC package. Confirm RoHS compliance status and ensure the specific revision matches the required datasheet version DS20001710M. Check for any automotive AEC-Q100 qualification requirements if applicable to the target environment.

Memory IC Selection Notes

Select this component when a 1 MHz I²C interface speed is required compared to slower 400 kHz alternatives like the 24LC08B. Ensure the application supports the 1.7V minimum supply voltage. Consider the 8-SOIC package dimensions for PCB layout constraints. Verify that the hardware write protect feature aligns with system security needs.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA08 and 24LC08B but offers distinct performance characteristics regarding voltage ranges and clock speeds. The family provides various packaging options including MSOP, TSSOP, and DFN variants for different form factor requirements.

Memory IC Replacement Considerations

The 24AA08T-I/SN serves as a direct substitute with identical pinout and functionality, though it operates at a lower maximum clock frequency of 400 kHz. The 24LC08BT-I/SN is another alternative but requires a higher minimum supply voltage of 2.5V and also limits operation to 400 kHz.
