AT25128B-SSPD-T

The AT25128B-SSPD-T is a type of serial EEPROM (Electrically Erasable Programmable Read-Only Memory) chip produced by Microchip Technology. It features a storage capacity of 128 Kbits, organized as 16,384 words of 8 bits each. The EEPROM uses a Serial Peripheral Interface (SPI) for communication, which allows for efficient data transfer. The "SSPD" in its name typically refers to its SOIC package, which is a common surface-mount form factor for integrated circuits.
Key features of the AT25128B include a wide operating voltage range, typically from 1.7V to 5.5V, and a significant endurance for write/erase cycles, often around 1 million cycles per byte, which ensures long-lasting performance. It also includes data protection features, such as write protection via the WP pin and software write protection mechanisms, to prevent accidental data corruption. The chip is used in applications where non-volatile memory is required to store small amounts of data that need to be retained even when power is removed, such as in consumer electronics, automotive systems, and industrial devices.
