AT24C04C-SSHM-T
Overview
The AT24C04C-SSHM-T is a 4-kilobit non-volatile serial EEPROM organized as 512 bytes of 8 bits each. It operates over a wide voltage range of 1.7V to 5.5V and utilizes an I2C-compatible 2-wire serial interface capable of speeds up to 1 MHz. This device is optimized for low-power industrial and commercial applications where reliable parameter storage is required in a small 8-SOIC form factor.
Why Choose This Part
This EEPROM offers high reliability with a rating of 1,000,000 write cycles and 100-year data retention. It features a 16-byte page write mode and a self-timed write cycle that completes within 5 ms, minimizing system latency during data updates. Integrated Schmitt Triggers and filtered inputs provide robust noise suppression for stable operation in noisy environments.
Applications
Key Specifications
Getting Started
Interface the AT24C04C via the I2C bus using a pull-up resistor on the SDA and SCL lines, typically 4.7k ohms for standard mode. Connect the WP pin to GND for normal read/write operations or to VCC to protect the entire memory array from writes. For development, use any standard I2C library on platforms like Microchip PIC, AVR, or Arduino, addressing the device based on the state of the hardwired address pins.
