The Microchip AT24C256C-SSPD-T: A Benchmark in Serial Memory Performance

In the realm of embedded systems and IoT devices, reliable non-volatile memory is a cornerstone for data storage and configuration settings. The Microchip AT24C256C-SSPD-T stands out as a premier solution, offering 256 kilobits (32 kilobytes) of Electrically Erasable Programmable Read-Only Memory (EEPROM) in a compact, industry-standard package. This device exemplifies high performance and robustness, making it an ideal choice for a vast array of applications.

Engineered for compatibility with the ubiquitous I2C (Inter-Integrated Circuit) protocol, this serial EEPROM facilitates simple two-wire communication, significantly reducing system interconnect complexity. It operates across a broad voltage range (1.7V to 5.5V), supporting both modern low-power microcontrollers and legacy 5V systems. A key feature is its enhanced hardware data protection. The inclusion of a hardware write-protect pin allows the host system to prevent inadvertent write operations, safeguarding critical data from corruption.

The memory array is organized as 32,768 words of 8 bits each, providing flexible byte-level and page-level read/write capabilities. With a 1 MHz (400 kHz and 1 MHz compatible) clock frequency, it ensures efficient data transfer rates. Furthermore, the device boasts exceptional endurance, supporting over 1 million write cycles and offering data retention of over 100 years, guaranteeing long-term reliability.

Its availability in an 8-lead SOIC package (-SSPD-T) makes it suitable for automated assembly processes. Typical applications range from storing calibration data in industrial systems and preserving user settings in consumer electronics to logging operational parameters in automotive subsystems.
