24FC128-I/MNY

Memory IC Overview

The Microchip Technology 24FC128-I/MNY is a 16K x 8 (128 Kbit) Serial Electrically Erasable PROM (EEPROM). It operates on a single supply voltage ranging from 1.7V to 5.5V and supports a maximum clock frequency of 1 MHz at VCC ≥ 2.5V, with 400 kHz compatibility at lower voltages. The device utilizes an I2C compatible two-wire serial interface and features a 64-byte page write buffer. It includes hardware write protection via the WP pin and offers data retention exceeding 200 years with over one million erase/write cycles.

Memory IC Feature Summary

• Supports high-speed 1 MHz operation for efficient data transfer in low-voltage environments
• Features a 64-byte page write buffer to optimize sequential write operations
• Includes hardware write-protect capability to secure memory arrays against unauthorized modifications

Memory IC Applications

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

Memory IC Procurement Notes

Verify that the specific suffix 'MNY' corresponds to the intended TDFN-8 package configuration as listed in the official datasheet selection table. Confirm the industrial temperature grade (-40°C to +85°C) aligns with system requirements. Ensure the 1.7V minimum operating voltage matches the target power supply design constraints before finalizing procurement.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I2C communication is required alongside low-voltage operation down to 1.7V. It is suitable for designs needing hardware write protection and long-term data retention. Compare against the 24LC128 if only 400 kHz speed is needed or against the 24AA128 if specific automotive qualification is not required but similar voltage ranges are desired.

Memory IC Part Context

This part belongs to the 24XX128 family of serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features including the I2C interface and page write capabilities. The 'FC' designation specifically indicates support for 1 MHz clock speeds and a wider voltage range starting at 1.7V compared to other variants in the series.

Memory IC Replacement Considerations

Direct substitutes within the same package include the 24FC128T-I/MNY for tape-and-reel packaging. Cross-family replacements like the 24LC128-I/MNY offer identical pinouts but are limited to 400 kHz operation.
