Description

The 25AA512T-I/SM is a 512 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) from Microchip Technology. It is organized into 64K x 8 bits and interfaces via a Serial Peripheral Interface (SPI) bus. This EEPROM features low-power consumption, with read currents typically around 5 mA and write currents about 5 mA. It operates within a voltage range of 1.8V to 5.5V, making it suitable for a wide range of applications.
The 25AA512T-I/SM supports byte-level and page-level write operations, with page sizes of 128 bytes. Data retention is typically over 40 years, and it can endure at least one million write cycles per bit. The device also features self-timed write cycles, sequential read capabilities, and hardware write protection via a write-protect pin. It is packaged in an 8-lead SOIJ (Small Outline Integrated Circuit) form factor.
Typical applications are in consumer electronics, industrial control, and communications systems, where non-volatile storage is required for configuration settings, calibration data, or other small to medium-sized data storage tasks.
