24LC128T-I/MNY

Memory IC Overview

The Microchip Technology 24LC128T-I/MNY is a 16K x 8 (128 Kbit) Serial Electrically Erasable PROM (EEPROM). It operates with a single supply voltage ranging from 2.5V to 5.5V and features an I2C compatible two-wire serial interface supporting up to 400 kHz clock frequency. The device includes Schmitt trigger inputs for noise suppression, hardware write protection, and output slope control to eliminate ground bounce. It supports page writes of up to 64 bytes and offers data retention exceeding 200 years with more than one million erase/write cycles.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using functional address lines A0, A1, and A2.
• Includes hardware write-protect capability via the WP pin to inhibit write operations when tied to VCC.
• Features Schmitt trigger inputs on SDA and SCL pins to provide improved noise spike suppression.

Memory IC Applications

• Personal communications systems requiring low-power non-volatile storage
• Data acquisition applications needing reliable parameter retention
• Industrial control systems utilizing I2C communication protocols

Memory IC Procurement Notes

Verify that the ordering suffix 'MNY' corresponds specifically to the 8-TDFN package type as documented in official Microchip datasheets. Confirm the temperature grade 'I' matches the required industrial operating range of -40°C to +85°C. Ensure compatibility with the 2.5V minimum supply voltage specification before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 128 Kbit EEPROM with I2C interface is required within the 2.5V to 5.5V voltage range. Consider the 8-TDFN package for surface-mount applications requiring compact footprints. Verify that the 400 kHz maximum clock speed meets system timing requirements and that hardware write protection aligns with security needs.

Memory IC Part Context

This part belongs to the 24XX128 family, which also includes the 24AA128 and 24FC128 variants. While sharing similar architecture and memory organization, these variants differ in supply voltage ranges and maximum clock frequencies. The 24LC128 specifically targets applications requiring operation down to 2.5V, distinguishing it from the wider voltage range options available in other family members.

Memory IC Replacement Considerations

Cross-reference with 24LC128T-I/MS or 24LC128T-I/MF if alternative TSSOP or DFN packages are needed. Verify electrical characteristics against 24AA128 or 24FC128 if different voltage or speed requirements arise.
