4 / 9 page CAT24WC01/02/04/08/16 4 Doc. No. 25051-00 3/98 S-1 FUNCTIONAL DESCRIPTION The CAT24WC01/02/04/08/16 supports the I2C Bus data transmission protocol. This Inter-Integrated Circuit Bus protocol defines any device that sends data to the bus to be a transmitter and any device receiving data to be a receiver. Data transfer is controlled by the Master device which generates the serial clock and all START and STOP conditions for bus access. The CAT24WC01/ 02/04/08/16 operates as a Slave device. Both the Mas- ter and Slave devices can operate as either transmitter or receiver, but the Master device controls which mode is activated. A maximum of 8 devices (24WC01 and 24WC02), 4 devices (24WC04), 2 devices (24WC08) and 1 device (24WC16) may be connected to the bus as determined by the device address inputs A0, A1, and A2. PIN DESCRIPTIONS SCL: Serial Clock The CAT24WC01/02/04/08/16 serial clock input pin is used to clock all data transfers into or out of the device. This is an input pin. SDA: Serial Data/Address The CAT24WC01/02/04/08/16 bidirectional serial data/ address pin is used to transfer data into and out of the device. The SDA pin is an open drain output and can be wire-ORed with other open drain or open collector outputs. A0, A1, A2: Device Address Inputs These inputs set device address when cascading mul- tiple devices. When these pins are left floating the default values are zeros (except for the 24WC01). A maximum of eight devices can be cascaded when Figure 2. Write Cycle Timing Figure 1. Bus Timing Figure 3.
