24FC128T-I/MNY

Memory IC Overview

The Microchip Technology 24FC128T-I/MNY is a 16K x 8 (128 Kbit) Serial Electrically Erasable PROM (EEPROM). It operates with a single supply voltage ranging from 1.7V to 5.5V and supports a maximum clock frequency of 1 MHz at VCC ≥ 2.5V, dropping to 400 kHz below that threshold. The device utilizes an I2C compatible two-wire serial interface and features a 64-byte page write buffer. It is housed in an 8-lead TDFN package and is rated for industrial temperature operation between -40°C and +85°C.

Memory IC Feature Summary

• Supports high-speed serial data transmission up to 1 MHz under appropriate voltage conditions
• Includes hardware write protection via the WP pin to secure memory arrays
• Features Schmitt trigger inputs designed to suppress noise spikes on communication lines
• Allows cascading of up to eight devices on a single bus using configurable chip select pins

Memory IC Applications

• Personal communications systems requiring non-volatile storage
• Data acquisition modules needing reliable parameter retention
• Industrial control units utilizing low-power memory interfaces

Memory IC Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage range compatibility with the target system power rails. Ensure the I2C bus pull-up resistor values align with the selected clock frequency to maintain signal integrity during high-speed operations.

Memory IC Selection Notes

Select this component when high-speed serial access is required within the 24XX128 family. It offers broader voltage tolerance compared to standard variants while maintaining compact surface-mount packaging. Consider the page write buffer size for applications involving frequent small data updates.

Memory IC Part Context

This part belongs to the 24XX128 series, which includes 24AA128 and 24LC128 variants. The 'FC' designation indicates high-speed capability up to 1 MHz. The 'I' suffix denotes industrial temperature range availability. The 'MNY' suffix specifies the 8-lead TDFN package configuration.

Memory IC Replacement Considerations

Direct substitutes include other 24FC128 variants with different package options such as SOIC or TSSOP. Cross-family replacements like 24LC128 offer similar functionality but are limited to 400 kHz speeds.
