Description
The 24AA512T-I/SN is a 512-Kbit serial Electrically Erasable Programmable Read-Only Memory (EEPROM) by Microchip Technology. It operates using the I²C bus protocol, which allows for communication with microcontrollers and other devices using just two wires: Serial Data (SDA) and Serial Clock (SCL). This EEPROM is designed for low-power applications, operating at a voltage range from 1.7V to 5.5V, making it suitable for battery-operated devices. The 24AA512T-I/SN offers a byte-level write capability and a page write capability of up to 128 bytes, providing flexibility in data storage and retrieval.
With a maximum clock frequency of 1 MHz in Fast Mode Plus, it supports quick data transfer, enhancing overall system performance. The device features self-timed write cycles for reliability and includes data protection features like write-protection for the entire memory or selected blocks. The EEPROM is encapsulated in an 8-lead SOIC package, making it easy to integrate into various electronic designs. Its high endurance and data retention of over 1 million write/erase cycles and more than 200 years, respectively, make it suitable for long-term data storage applications.
