AT24C04D-STUM-T: A Deep Dive into Microchip's 4Kb Serial EEPROM 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 AT24C04D-STUM-T from Microchip Technology stands out as a robust and efficient solution designed to meet these critical needs. This 4Kbit I2C-compatible Serial EEPROM memory chip combines high performance with industry-standard communication, making it an ideal choice for a vast array of applications.
Core Features and Architectural Advantages
The AT24C04D-STUM-T is organized as 512 x 8 (4Kbits), providing ample space for essential data storage. Its operation via a simple, two-wire I2C serial interface allows for communication with a microcontroller using only two bus lines: a serial data line (SDA) and a serial clock line (SCL). This significantly reduces system pin count and simplifies PCB layout. The device supports a wide voltage range from 1.7V to 5.5V, ensuring compatibility with both modern low-power processors and legacy 5V systems.
A key feature of this EEPROM is its 1MHz (1.7V to 5.5V) compatibility, enabling high-speed data transfer across its entire operating voltage range. For enhanced design flexibility, the chip incorporates a hardware write-protect pin that safeguards the entire memory array from unintended writes, a crucial function for ensuring data integrity in noisy environments or during power-up/power-down sequences.
Enhanced Reliability and Packaging
Built for durability, the AT24C04D-STUM-T is engineered for endurance of 1 million write cycles and offers a formidable data retention period of 100 years. These specifications guarantee that data remains intact through countless updates and over the extremely long operational life of the end product. The device is offered in a space-saving 8-lead TSSOP package, making it suitable for space-constrained applications like wearables, sensors, and compact consumer electronics.
Diverse Application Spectrum
The versatility of this memory chip allows it to be deployed across numerous industries. It is perfectly suited for:
Smartphones and Tablets: Storing device-specific data and user settings.
Industrial Automation: Holding calibration data and system configuration parameters.
Medical Equipment: Ensuring critical device settings are retained securely.
Automotive Electronics: Used in infotainment systems and module configuration.
IoT Modules: Providing essential non-volatile memory for sensor data logging and network information.
The AT24C04D-STUM-T from Microchip Technology is a superior choice for designers seeking a high-reliability, low-power, and interface-efficient serial EEPROM. Its robust feature set, including a wide voltage range, hardware write-protection, and industry-standard I2C interface, makes it an indispensable component for ensuring data persistence in modern electronic designs.
