USAGES
1. Interfacing with the CPU
The RS5C372A/B employ the I
2C bus system to be connected to the CPU via 2-wires. Connection and transfer sys-
tem of I
2C bus are described in the following sections.
Note
I
2C bus is a trademark of PHILIPS ELECTRONICS N.V.
1.1 Connection of I
2C bus
2-wires, SCL and SDA which are connected to I
2C bus are used for transmit clock pulses and data respectively.
All ICs that are connected to these lines are designed that will be not be clamped when a voltage beyond supply volt-
age is applied to input or output pins. Open drain pins are used for output. This construction allows communication
of signals between ICs with different supply voltages by adding a pull-up resistor to each signal line as shown in the
figure below. Each IC is designed not to affect SCL and SDA signal lines when power to each of these is turned off
separately.

*1) For data interface, the following conditions must be met:
VDD4
≥VDD1
VDD4
≥VDD2
VDD4
≥VDD3
*2) When the master is one, the microcontroller is ready for
driving SCL to “H” and RP of SCL may not be required.
