MCHP24LC256-I/SN
Overview
The 24LC256-I/SN is a 256-Kbit (32K x 8) I2C serial EEPROM designed for low-power applications requiring non-volatile storage. It operates across a voltage range of 2.5V to 5.5V and supports up to eight devices on a single two-wire bus. With a standby current of only 1 uA, it is highly efficient for battery-powered systems.
Why Choose This Part
This EEPROM features a large 64-byte page write buffer and Schmitt trigger inputs for noise suppression in harsh environments. It is rated for over one million erase/write cycles and provides exceptional data retention of more than 200 years. The integrated output slope control helps eliminate ground bounce, improving signal integrity in high-speed I2C designs.
Applications
Key Specifications
Getting Started
Connect the device to an I2C controller using the SDA and SCL pins with 4.7k-ohm pull-up resistors. Use the three address pins (A0, A1, A2) to set the unique hardware address if multiple devices are on the same bus. Ensure the WP pin is tied to GND for write operations or VCC to hardware-protect the entire memory array.
