MCHP24LC04B

Overview

The 24LC04B is a 4Kbit I2C serial EEPROM from Microchip Technology, organized as two blocks of 256 x 8-bit memory. It operates over a wide voltage range of 2.5V to 5.5V and is designed for low-power applications with a standby current of only 5uA. This non-volatile memory solution is AEC-Q100 qualified, making it suitable for automotive and industrial environments requiring high reliability.

Why Choose This Part

This EEPROM offers high endurance with over 1 million erase/write cycles and data retention exceeding 200 years. It features Schmitt Trigger inputs for noise suppression and output slope control to minimize ground bounce, ensuring robust I2C communication at speeds up to 400 kHz.

Applications

Getting Started

To evaluate the 24LC04B, engineers can use the Microchip MPLAB Starter Kit for Serial Memory Products or connect the PDIP variant (24LC04B-I/P) to any I2C-capable microcontroller like a PIC or AVR. Implementation requires a simple two-wire interface with pull-up resistors, and the hardware write-protect pin should be tied to VSS for normal write operations.
