M24128-DFDW6TP

Memory IC Overview

The M24128-DFDW6TP is a 128-Kbit serial I2C bus EEPROM manufactured by STMicroelectronics. It features an I2C interface with a maximum clock frequency of 1 MHz and an access time of 450 ns. The memory is organized as 16 k x 8 bits within an 8-TSSOP package. Operating voltage ranges from 1.7 V to 5.5 V, supporting operation across temperatures from -40°C to +85°C. Data retention is specified at 200 years.

Memory IC Feature Summary

• Supports Fast-mode Plus (1 MHz), Fast-mode (400 kHz), and Standard-mode (100 kHz) I2C communication protocols.
• Includes a dedicated 64-byte identification page for storing sensitive application parameters that can be permanently locked in read-only mode.
• Provides hardware write protection for the entire memory array to ensure data integrity.

Memory IC Applications

• Smart grid distribution systems
• Smart metering applications
• Industrial control systems requiring non-volatile parameter storage

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS3 compliance status and check for specific Package Change Notices (PCN) regarding label or assembly updates. Ensure the selected variant matches the required supply voltage range and temperature specifications for the target environment.

Memory IC Selection Notes

Select this component when a 128-Kbit capacity with I2C connectivity is required. The DF suffix indicates support for the 1.7 V to 5.5 V operating range. Consider the DW suffix for the TSSOP-8 surface mount package. Verify if the additional identification page functionality is necessary for the specific application requirements compared to standard variants.

Memory IC Part Context

This device belongs to the M24128 series of serial EEPROMs designed for low-power and high-reliability applications. The series offers various package options including TSSOP, WLCSP, and UFDFPN. The M24M01 series represents a higher density alternative within the same product family, sharing similar interface characteristics but offering 1-Mbit capacity.

Memory IC Replacement Considerations

M24128-BWDW6TP: Compatible alternative with a 2.5 V to 5.5 V supply voltage range. M24128-BRDW6TP: Compatible alternative with a 1.8 V to 5.5 V supply voltage range. Verify voltage compatibility before substitution.
