MCHPAT24C04D-PUM
Overview
The AT24C04D-PUM is a 4Kbit serial EEPROM organized as 512 words of 8 bits each, featuring a 2-wire I2C interface. This part is housed in an 8-pin PDIP package, making it ideal for through-hole prototyping and educational environments. It operates across a wide voltage range of 1.7V to 3.6V with a high-speed 1MHz clock frequency capability.
Why Choose This Part
The component offers extremely low power consumption with a standby current of only 1 microamp. Its PDIP-8 form factor provides mechanical robustness for socketed applications and simplified manual assembly. Additionally, the 1MHz clock support ensures faster data transfers compared to standard 100kHz or 400kHz I2C EEPROMs.
Applications
Key Specifications
Getting Started
To interface with this EEPROM, connect the SDA and SCL lines to your microcontroller with appropriate pull-up resistors and tie the WP pin to GND for write operations. Use standard I2C libraries such as the Arduino Wire library or Microchip's MCC for easy data read/write implementation. Ensure your supply voltage remains within the 1.7V to 3.6V range for the D-variant.
