24FC128T-I/MF

Memory IC Overview

The Microchip Technology 24FC128T-I/MF is a 16K x 8 (128 Kbit) Serial Electrically Erasable PROM (EEPROM). It features a two-wire I2C compatible interface with a maximum clock frequency of 1 MHz at VCC ≥ 2.5V, and 400 kHz at VCC < 2.5V. The device operates on a single supply voltage ranging from 1.7V to 5.5V. It includes a 64-byte page write buffer, hardware write-protect capability via the WP pin, and supports up to eight devices on the same bus. The industrial temperature grade (-I) covers -40°C to +85°C, housed in an 8-lead DFN-S package.

Memory IC Feature Summary

• High-speed serial communication with I2C compatibility supporting up to 1 MHz operation
• Low-power CMOS technology enabling operation down to 1.7V supply voltage
• Hardware write protection controlled by the dedicated WP pin
• Robust data retention exceeding 200 years and high endurance

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix 'MF' corresponds to the 8-lead DFN-S package configuration during procurement. Confirm that the 'I' designation matches the required industrial temperature range of -40°C to +85°C for your application environment. Ensure voltage levels align with the 1.7V to 5.5V operational specification.

Memory IC Selection Notes

Select this component when high-speed I2C access up to 1 MHz is required alongside low-voltage operation starting at 1.7V. It is suitable for designs needing hardware write protection and compact surface-mount packaging. Consider the 64-byte page write buffer for efficient data writing operations within the memory array constraints.

Memory IC Part Context

This part belongs to the 24XX128 family, which includes the 24AA128 and 24LC128 variants. While sharing similar memory organization and interface protocols, the 24FC128 distinguishes itself with higher clock speed capabilities at lower voltages compared to the standard 400 kHz models. The family supports various packages including SOIC, TSSOP, and DFN formats.

Memory IC Replacement Considerations

Direct substitutes include other 24FC128 variants with different package options such as 24FC128-I/MS or 24FC128-I/MNY. Cross-family replacements like 24LC128 or 24AA128 are functionally compatible but operate at lower maximum clock frequencies.
