The 11AA020-I/TO is a serial Electrically Erasable Programmable Read-Only Memory (EEPROM) IC (Integrated Circuit) manufactured by Microchip Technology. It has a memory capacity of 2 kilobits (256 bytes) and operates on a supply voltage range of 2.7V to 5.5V. The IC is housed in an industry-standard 8-pin small outline integrated circuit (SOIC) package with a wide operating temperature range of -40°C to 85°C.
The 11AA020-I/TO features a two-wire I2C serial interface for easy interfacing with microcontrollers, allowing for easy integration into various embedded systems. It also has a write protect function that prevents accidental write operations to the memory, ensuring data integrity. The IC offers high reliability with a guaranteed endurance of 1 million write cycles and a data retention period of 200 years.
In addition, the 11AA020-I/TO features a hardware write protect pin for added security, as well as a software write protection scheme for flexible control of memory access. It has a fast write cycle time of less than 5ms and low power consumption, making it suitable for battery-powered applications. The IC is RoHS compliant and widely used in applications such as industrial controls, automotive systems, consumer electronics, and more
