Microchip AT24C04C-STUM-T: A Robust 4-Kbit Serial I2C EEPROM Solution

In the realm of non-volatile memory, serial EEPROMs play a critical role in storing crucial configuration, calibration, and data-logging information across a vast array of electronic applications. The Microchip AT24C04C-STUM-T stands out as a highly reliable and efficient solution, offering 4 Kbits (512 x 8) of electrically erasable programmable read-only memory. This device is engineered to deliver performance and durability for modern embedded systems.

A key strength of the AT24C04C lies in its utilization of the ubiquitous I2C (Inter-Integrated Circuit) serial interface. This two-wire protocol minimizes the required GPIO pins on a host microcontroller, simplifying board layout and reducing system cost. The chip supports a wide voltage range from 1.7V to 5.5V, making it exceptionally versatile for use in both low-power and mainstream applications, from battery-operated IoT sensors to industrial control systems.

The memory array is organized as a single block of 512 bytes. It features a sophisticated write-protection scheme that can be configured via the WC (Write Control) pin, allowing the entire array to be hardware-protected against unintended writes. Furthermore, the AT24C04C is designed for high reliability, enduring over 1 million write cycles and boasting a data retention period of up to 100 years, ensuring data integrity over the product's entire lifespan.

Internally, the device incorporates a 32-byte page write buffer, enabling more efficient data transfer by allowing up to 32 bytes to be written in a single I2C bus cycle. This significantly reduces write time and improves overall system throughput. The AT24C04C-STUM-T is offered in a space-saving 5-lead SOT-23 package, ideal for applications where PCB real estate is at a premium. Its extended industrial temperature range (-40°C to +85°C) guarantees stable operation in harsh environments.

ICGOODFIND: The Microchip AT24C04C-STUM-T is a premier choice for designers seeking a compact, reliable, and easy-to-integrate non-volatile memory solution. Its combination of a standard I2C interface, robust endurance, wide voltage operation, and tiny form factor makes it an excellent component for countless embedded designs.
