The Microchip AT24C08D-SSHM-B: A Robust 8-Kbit Serial EEPROM for Modern Designs

In the realm of non-volatile memory, serial EEPROMs remain a fundamental component for storing critical data in a vast array of electronic systems. The Microchip AT24C08D-SSHM-B stands out as a reliable and efficient solution, offering 8 Kbits (1024 bytes) of electrically erasable programmable read-only memory. This device is engineered to meet the demanding requirements of industrial, automotive, and consumer applications, providing a simple yet powerful method for storing configuration parameters, calibration data, and user settings.

Operating over a broad voltage range of 1.7V to 5.5V, the AT24C08D-SSHM-B is exceptionally versatile, supporting both modern low-power microcontrollers and legacy 5V systems. Its low standby current makes it ideal for power-sensitive, battery-operated devices. Communication is handled via the ubiquitous I2C-compatible (2-wire) serial interface, which minimizes board space and simplifies design complexity by requiring only two bus lines for data transfer. This interface supports a clock frequency of up to 1MHz (at 5V), enabling high-speed read and write operations for improved system performance.

A key feature of this EEPROM is its enhanced data integrity and reliability. The memory array is organized as 128 pages of 8 bytes each, supporting both byte-level and page-level write operations. The device incorporates hardware data protection through programmable write protection via dedicated pins (WP), safeguarding critical memory sections from accidental overwrites. Furthermore, it is designed for high endurance, capable of 1 million write cycles and featuring a data retention period of up to 100 years, ensuring long-term data integrity.

Housed in a space-saving 8-lead SOIC package, the AT24C08D-SSHM-B is built to operate across the industrial temperature range (-40°C to +85°C), guaranteeing stable performance in harsh environmental conditions. Its combination of density, low power consumption, and robust packaging makes it a superior choice for designers seeking a dependable memory solution.

ICGOODFIND: The Microchip AT24C08D-SSHM-B is a highly integrated and reliable 8-Kbit serial EEPROM. Its wide voltage operation, robust I2C interface, and exceptional endurance make it an excellent choice for ensuring data persistence and system configurability across a diverse spectrum of electronic applications.
