Description

The 25AA128T-I/SN is a Microchip Technology serial EEPROM (Electrically Erasable Programmable Read-Only Memory) device. It features 128 kilobits of memory organized as 16,384 bytes, making it suitable for applications requiring non-volatile storage. This EEPROM operates on a low-voltage range of 1.8V to 5.5V, making it energy-efficient for various electronic applications.
Key features include a Serial Peripheral Interface (SPI) that supports high-speed data transfer and provides a simple interface for communication with microcontrollers and other devices. It also has a write-protect pin to safeguard against accidental data overwrites, and it supports byte-level or page-level data writing.
The 25AA128T-I/SN is housed in an 8-pin SOIC package, making it easy to integrate into circuit designs. Its endurance is rated at 1,000,000 erase/write cycles, with data retention of over 200 years, ensuring long-term reliability. This makes it ideal for applications like data logging, calibration storage, and other uses where dependable data retention is crucial.
