The 24AA512/24LC512/24FC512 (24XX512*) from Microchip Technology Inc. is a 64K x 8 (512 Kbit) Serial Electrically Erasable PROM that can operate over a wide voltage range (1.7V to 5.5V). It was created for cutting-edge, low-power applications including data collection and personal communications. Additionally, this device has a page write capacity of up to 128 bytes of information. Both random and sequential readings up to the 512K barrier are supported by this device. Up to eight devices can share a bus with functional address lines, providing a maximum address space of 4 Mbit. The common 8-pin plastic DIP, SOIJ, SOIC, TSSOP, DFN, and 14-lead TSSOP packaging are also available for this component. The 8-lead Chip Scale package is another option for the 24AA512.

The AT24C512C functions as a slave device and communicates with a host controller, also known as the bus master, using a straightforward two-wire digital serial interface that is I2C-compatible. On a serial bus, the master initiates and manages all read and write operations to slave devices, and both the master and slave devices are capable of sending and receiving data. Just two signal lines—Serial Clock (SCL) and Serial Data—make up the serial interface (SDA). The bilateral SDA pin is used to receive command and detailed empirical from the master as well as to transmit data back to the master, while the SCL pin is used to accept the clock signal from the master. To reduce the impact of input spikes and bus noise, the SCL and SDA pins each include Schmitt Triggers and inbuilt spike suppression filters. The Most Significant bit (MSb) is always transmitted first when sending commands or data. After eight bits (one byte) of information have been exchanged during bus communication, the receiving device must answer with an Acknowledge (ACK) or No-Acknowledge (NACK) response bit during such a ninth clock cycle (ack/nack clock cycle) produced by the master. As a result, nine clock cycles are needed to send one byte of data. There must be no gaps or interruptions throughout any data transfer operation since there are no spare clock cycles.
