24AA52-I/ST

The Microchip Technology 24AA52-I/ST is a 2 Kbit serial EEPROM designed for low-power applications, operating from a single supply voltage ranging from 1.8V to 5.5V. This device features a 2-wire serial interface bus compatible with I2C standards, enabling efficient data communication.

Key electrical characteristics include a memory organization of 256 x 8 bits, a maximum clock frequency of 400 kHz, and an access time of 900 ns. The device supports a write cycle time of 5ms. It is built using low-power CMOS technology, with typical active current of 1 mA and standby current of 1 µA.

Designed for industrial temperature ranges, the 24AA52-I/ST operates from -40°C to +85°C. It is supplied in an 8-TSSOP package suitable for surface mounting. The device also offers features such as Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce, making it suitable for various embedded systems.

This EEPROM provides a data retention capability exceeding 200 years and can withstand 1,000,000 erase/write cycles. It includes hardware write protection for the entire array and software write protection for the lower 128 bytes, offering flexibility in data security.
