MCHP24LC64

Overview

The 24LC64 is a 64 Kbit I2C serial EEPROM organized as 8K x 8 bits, designed for low-power applications with a supply voltage range of 2.5V to 5.5V. It features Schmitt Trigger inputs for noise suppression and output slope control to minimize ground bounce, making it reliable for data storage in noisy environments.

Why Choose This Part

This EEPROM offers high reliability with over 1 million write cycles and integrated ESD protection exceeding 4,000V. Its hardware write-protect pin provides robust data security against accidental overwrite, while its low standby current of 1 uA minimizes power consumption in battery-operated devices.

Applications

Getting Started

To interface with the 24LC64, connect the SDA and SCL lines to your microcontroller with external pull-up resistors, usually 4.7k to 10k ohms. Ensure the hardware Write-Protect (WP) pin is tied to GND if you need to perform write operations, or to VCC to lock the memory. It is compatible with standard I2C drivers supporting 400 kHz clock frequencies.
