Microchip AT24C08D-SSHM-T: A Robust 8-Kbit Serial EEPROM for Modern Embedded Systems

The Microchip AT24C08D-SSHM-T is a high-performance 8-Kbit (1024 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) designed for reliability and efficiency in a wide range of applications. This memory chip utilizes the ubiquitous I2C (Inter-Integrated Circuit) protocol for communication, making it an ideal choice for system designers seeking a simple, two-wire interface to manage non-volatile data storage.

A key feature of this device is its advanced write protection scheme. The entire memory array can be hardware write-protected using the WC (Write Control) pin, safeguarding critical data from accidental corruption. Furthermore, the chip supports partial array protection, allowing specific sections of the memory to be locked while leaving others accessible for read and write operations. This flexibility is crucial for applications requiring secure boot parameters or calibration constants alongside dynamic data storage.

The AT24C08D-SSHM-T is engineered for low-power operation, a critical requirement for battery-powered and portable devices. It boasts very low active and standby current consumption, significantly extending the operational life of the end product. Its extended voltage range from 1.7V to 5.5V ensures compatibility with various logic levels and provides design engineers with greater flexibility in power supply design.

Packaged in the space-saving 8-lead SOIC, this EEPROM is suited for compact PCB layouts. Its industrial temperature rating (-40°C to +85°C) guarantees stable and reliable performance across harsh environmental conditions, from consumer electronics to industrial automation and automotive systems. The device also supports a 1 MHz clock frequency, enabling high-speed data transfer for time-sensitive applications.

ICGOOODFIND: The Microchip AT24C08D-SSHM-T stands out as a highly reliable and versatile serial EEPROM solution. Its combination of a standard I2C interface, robust data protection mechanisms, low power consumption, and a wide operating voltage range makes it an excellent choice for designers needing dependable non-volatile memory in space-constrained and power-sensitive applications.
