M24C64-RMN6TP 64-Kbit I²C Serial EEPROM | SOIC-8 Memory IC | STMicroelectronics

M24C64-RMN6TP

64-Kbit (8K × 8) serial EEPROM with I²C bus interface, operating from 1.8 V to 5.5 V, supporting up to 1 MHz clock frequency in an SOIC-8 package, ideal for configuration storage, parameter retention, and small data logging in embedded systems.

Product Description

Product Overview

The M24C64-RMN6TP from STMicroelectronics is a 64-Kbit serial EEPROM organized as 8K × 8 bits, accessed via an I²C-compatible bus, providing non-volatile storage for system parameters, calibration data, and configuration values.

It supports standard, fast, and higher-speed I²C modes with clock frequencies up to 1 MHz, and its 1.8 V–5.5 V supply range allows easy integration into 1.8 V, 3.3 V, or 5 V digital systems.

Packaged in an SOIC-8 surface-mount outline and specified for –40°C to +85°C operation, the M24C64-RMN6TP is suited for long-term reliable EEPROM storage in both industrial and consumer applications.
