GENERAL DESCRIPTION
In addition, the 24C08 / 24C16 is available in 1.8V (1.8V to 5.5V) version. Pin Configuration 1/15 MRD 24C08/24C16 Pin Descriptions Pin number 1–3 5 6 7 4 8 1 Designation A0 - A2 SDA SCL WP GND VCC NC Type I I/O & Open-drain I I P P NC Name and Functions Address Inputs DEVICE/PAGE ADDRESSES (A2, A1, A0): The AT24C08 only uses the A2 input for hardwire addressing and a total of two 8K devices may be addressed on a single bus system. The AT24C16 does not use the device address pins, which limits the number of devices on a single bus to one. The A0, A1 and A2 pins are no connects and can be connected to ground. Serial Data SERIAL DATA (SDA): The SDA pin is bi-directional for serial data transfer. This pin is open-drain driven and may be wire-ORed with any number of other open-drain or opencollector devices. Serial Clock Input SERIAL CLOCK (SCL): The SCL input is used to positive edge clock data into each EEPROM device and negative edge clock data out of each device. Write Protect WRITE PROTECT (WP): The 24C08/24C16 has a Write Protect pin that provides hardware data protection.
