MCHPAT24C16B

Overview

The AT24C16B is a 16-Kbit serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 2048 words of 8 bits each. It utilizes an I2C (2-wire) interface and is designed for low-power and low-voltage applications, operating across a wide voltage range of 1.8V to 5.5V. The device features noise suppression on inputs and a hardware write-protect pin for data security.

Why Choose This Part

This EEPROM offers high reliability with a low standby current of 1uA and a write current of 2.0mA at 5.0V. It supports 16-byte page writes and includes a hardware write-protect pin to prevent accidental data corruption. The Schmitt Trigger and filtered inputs ensure robust communication in electrically noisy environments.

Applications

Getting Started

To interface with the AT24C16B, connect the SDA and SCL lines to your microcontroller's I2C bus with appropriate pull-up resistors. Ensure the WP pin is tied to GND for write operations or VCC to protect the memory. Development is straightforward using standard I2C libraries such as the Wire library for Arduino or the HAL drivers for STM32.
