Overview

The M24C64-WMN6TP is a 64-Kbit I2C compatible EEPROM organized as 8192 x 8 bits. Operating within a voltage range of 2.5V to 5.5V, it features high reliability with 4 million write cycles and a data retention period exceeding 200 years. This device is housed in a standard 8-pin SO8N package and supports clock frequencies up to 1MHz.

Why Choose This Part

This component offers exceptional endurance with 4 million write cycles, significantly outperforming standard EEPROMs for high-frequency write operations. It provides robust protection with enhanced ESD/latch-up ratings and includes a hardware write-protect pin for securing the entire memory array against accidental overwrites.

Applications

Configuration Storage
Storing calibration data, user preferences, and system configuration parameters in industrial and consumer electronics.
Device Identification
Retaining MAC addresses, serial numbers, and security keys that require long-term persistence.
Data Logging
Recording periodic sensor readings or event logs in low-power battery-operated devices.
Firmware Parameters
Holding lookup tables and operational constants that are updated infrequently during the product lifecycle.

Getting Started

To integrate the M24C64-WMN6TP, connect the SCL and SDA lines to an I2C controller with appropriate pull-up resistors and configure the three chip-enable pins (E2, E1, E0) to set the device address. Engineers can utilize standard I2C libraries such as the Arduino Wire library or STM32 HAL I2C drivers to perform byte and page writes. Ensure the WP pin is tied to VSS during write operations and to VCC for hardware-based data protection.
