Microchip 2 kB Serial EEPROM 900 ns 5-Pin SOT-23 Serial-I2C 24AA02T-I/OT

Microchip model 24AA02T-I/OT is a 2 kbit Serial EEPROM designed for industrial and automotive applications requiring fast, reliable non-volatile memory storage. Packaged in a compact 5-pin SOT-23 surface mount device, it supports a maximum clock frequency of 400 kHz over a serial I2C interface which facilitates easy integration into modern electronic circuits.

The device operates on a single low voltage supply ranging from 1.7V up to 5.5V, enabling energy-efficient operation. It features low read current consumption of 1 mA maximum, and a standby current as low as 1 μA, making it ideal for battery-powered or energy-sensitive systems.

With an access time of only 900 ns, data can be retrieved swiftly. The device offers high endurance with more than one million erase/write cycles, and a data retention life exceeding 200 years, ensuring long-term data reliability.

Additional features include an 8-byte page write buffer to accelerate memory write procedures and hardware write-protect capabilities for enhanced data security. Schmitt trigger inputs provide noise suppression and output slope control prevents ground bounce effects, improving signal integrity in demanding environments.

The 24AA02T-I/OT is tested and qualified to automotive industry standard AEC-Q100, making it suitable for rigorous automotive system use as well as other embedded industrial applications. Dimensions are 2.9 mm length, 2.8 mm width, and 1.45 mm height, fitting compact board layouts.
