AT24C04C-SSPD-T: A Deep Dive into a 4-Kbit I2C Serial EEPROM Memory Solution

In the realm of embedded systems and IoT devices, the need for reliable, non-volatile memory for storing configuration data, calibration constants, and operational parameters is paramount. The AT24C04C-SSPD-T stands out as a robust and efficient solution, offering 4 kilobits (512 bytes) of electrically erasable programmable read-only memory (EEPROM). This device is engineered for low-power and low-voltage operation, making it an ideal choice for a vast array of consumer, industrial, and automotive applications.

A key feature of the AT24C04C is its utilization of the ubiquitous I2C (Inter-Integrated Circuit) serial interface. This two-wire serial protocol, comprising a bidirectional data line (SDA) and a clock line (SCL), significantly reduces the number of pins required for communication with a host microcontroller. This simplicity leads to reduced board space, lower system cost, and simplified layout. The device supports a maximum clock frequency of 1MHz (Fast-mode Plus), enabling high-speed data transfer and improving overall system performance.

The memory array is organized as 512 words of 8 bits each, providing the necessary flexibility for storing diverse data types. For enhanced design flexibility, the full 4-Kbit address space is accessible using a two-wire serial interface. The integrated write-protect (WP) pin offers crucial software and hardware data protection mechanisms, preventing inadvertent write operations and ensuring data integrity in noisy environments or during power transitions.

Designed for endurance and longevity, the AT24C04C is specified for over 1 million write cycles and boasts a data retention period of up to 100 years. Its operating voltage range is from 1.7V to 5.5V, allowing it to function seamlessly in systems from the latest low-power microcontrollers to legacy 5V designs. The compact and industry-standard 8-lead SOIC package ensures easy integration into new and existing designs.

ICGOODFIND: The AT24C04C-SSPD-T is a highly reliable and versatile serial EEPROM. Its combination of the standard I2C interface, robust data protection features, extensive endurance, and wide voltage operation makes it a superior choice for designers seeking a proven non-volatile memory solution for space-constrained and power-sensitive applications.
