24FC01T-E/SN

Memory IC Overview

The Microchip Technology 24FC01T-E/SN is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) featuring a 2-wire I2C compatible serial interface. It supports a maximum clock frequency of 1 MHz and operates on a single supply voltage ranging from 1.7 V to 5.5 V. The device utilizes low-power CMOS technology with a maximum active read current of 1 mA and standby current of 3 µA at extended temperatures. It offers hardware write protection, an 8-byte page write buffer, and data retention exceeding 200 years. The component is housed in an 8-lead SOIC package and is rated for an operating temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication with Schmitt trigger inputs for noise suppression.
• Features hardware write protection via the WP pin to inhibit memory writes when tied to VCC.
• Includes an 8-byte page write buffer to optimize data transfer efficiency.
• Provides robust ESD protection exceeding 4,000V and long-term data retention.

Memory IC Applications

• Non-volatile data storage in industrial control systems
• Configuration parameter storage in automotive electronics
• Device identification and calibration data logging

Memory IC Procurement Notes

Verify that the ordering suffix 'E' confirms the Extended temperature grade (-40°C to +125°C) and 'SN' specifies the 8-lead SOIC package. Confirm the 'T' suffix indicates tape and reel packaging if required for automated assembly. Ensure the specific revision matches the datasheet DS20001711M for accurate electrical characteristics.

Memory IC Selection Notes

Select this part for applications requiring 1 MHz bus speeds and operation down to 1.7 V. The Extended temperature grade is suitable for harsh environments up to +125°C. Compare against the 24AA01 or 24LC01B variants if lower speed or different voltage thresholds are acceptable. Ensure the system design accommodates the open-drain SDA line requirements.

Memory IC Part Context

This component belongs to the 24XX01 family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA01 and 24LC01B but distinguishes itself through higher clock frequency support and broader voltage compatibility. The family utilizes a standardized I2C protocol for efficient microcontroller interfacing.
