FUNCTIONAL DESCRIPTION
The R8A66153FP is a general purpose programmable I/O expander with three 8-bit I/O ports (portA,B,C) and two 8-bit high voltage output ports (portE,F) and one 4-bit input port (portG). I/O ports can be set INPUT for OUTPUT by a command. The portC can be divided into two 4-bit ports, and if it is set to output, bit set/reset operation is available. The portE and port F is the high voltage N-channel open drain output. (Vo=24V, IOL=24mA) The port G is a 4-bit input port with CMOS level schimitt trigger input. When RESET="H", output port E and F turn to disable state and other I/O ports turn to input mode.
FUNCTION
RD (read input) If the input is "L", the port input data or port latch data appear at the data bus. WR (write input) By the positive edge of WR input, data bus data is written into the control register or into the port latch. A2, A1, A0 (Port selection input) Select the port or the control register. (see table 1) RESET (reset input) If the input is "H", all I/O and output port turn to high impedance state. (Port A,B,C : input mode, Port E,F : "Z") CS (chip select input) "L" enables to communicate with MCU. When "H", data bus keeps high impedance state and ignored the command from MCU. The port condition and the data of the port latch are not changed even if CS="H". Read/Write control circuit According to the data from the MCU, set the port condition and transmit the data between port and data bus. Data bus buffer This is the bi-directional bus buffer. When WR="L" data bas data is written into the register of R8A66153, and when RD="L" port data or port latch data is appears. Port A and Port B Port A and Port B are 8-bit bi-directional port with output latch. By the command from MCU, set these port as an input or an output. The output circuit of these ports are CMOS 3-state output and input buffer is CMOS schmitt trigger input. When port is set to output, data bus data is written into the port latch by the positive edge of /WR and is output to the terminal. When RD="L" in the state of output mode, port terminal data(=output data) is appears to the data bus. When RD="L" in the state of input mode, port terminal data(=input data) is appears to the data bus. In the state of input mode, data bus data is written into the port latch by the positive edge of WR.
Port latch data is not determined when power ON.
Port C Basic function of port C is the same as the port A and port B. The difference between port A/B and port C is that port C can be used as the two 4-bit ports. And when is set to output, bit set/reset function is available by a bit.

R8A66153FP
Port E and Port F Port E and Port F are 8-bit high voltage output ports with Vo=24V/IOL=24mA. Output transistor is N-ch open drain transistor. When this port is selected, data bus data is written into the port latch by the positive edge of WR. And if is set to output enable, port latch Port G Port G is a input port with CMOS schmitt trigger. When this port is selected and RD="L", input data is appears to the data bus.
