On April 1st, 2010, NEC Electronics Corporation merged with Renesas Technology
Corporation, and Renesas Electronics Corporation took over all the business of both
companies. Therefore, although the old company name remains in this document, it is a valid
Renesas Electronics document. We appreciate your understanding.

5. Setup
The board combined with this board (M3A-0040) is called a target board in the description below.
This section illustrates how to use this board with a target board to connect to a USB device.
5.1 Using with M3A-0033
M3A-0033 is the Renesas USB ASSP Evaluation Motherboard. It is possible to test the R8A66597FP easily by
combining it with this board and the M3A-0033. But, it isn’t possible to test the R8A66597FP’s split bus.
How to use the M3A-0040 with the M3A-0033 is shown as below.
(1) Setting of switch and jumper
(a) Set SW1 to “SEPA”. (“SEPA” is factory setting)
(b) Set JP4 to “3.3 V”. (“3.3V” is factory setting)
(2) Connecting the M3A-0040 to the M3A-0033
Insert CN2’s #1-pin and #2-pin of the M3A-0040 board to CN8’s #1-pin and #2-pin of the M3A-0033 to connect
the two boards together.
(3) VBUS output for host function
Apply 5V to CN4 of the M3A-0040 board using the power supply cable included. The red wire is 5V and the
black one is GND.
(a) When output VBUS to CN1:
(i) Set high level output to VBOUT0 pin of the R8A66597 by software.
(ii) Set JP6 to "HOST".
(b) When output VBUS to CN5:
(i) Set high level output to VBOUT1 pin of the R8A66597 by software.
It is possible to operate the R8A66597FP using the remote debugger KD308 that is attached to the M3A-0033.
Please refer to the M3A-0033 Instruction Manual“.

5.2 Use with other boards
The R8A66597FP corresponds to a separate bus mode and multiplex bus mode. Switch SW1 of the M3A-0040
according to MCU use. Below are notes for target board design.
5.2.1 Notes for target board design
(1) The receptacle of the target board should suit the size of this board (refer to Figure 3 and Figure 4). Make
pin arrangement the same as this board (refer to Table 1 and Table 2). Please refer to Appendix 1: the
M3A-0040 Part List and Appendix 2: the Circuit Diagram, when selecting connector and pin arrangement.
The HKP-50FD2 from Honda Tsushin Kogyo is applicable to the target board.
(2) To prevent misinsertion, please carry out stuffing the pins of target board that correspond to the #21-pin
and #22-pin of CN2 of this board. When HKP-50FD2 of Honda Tsushin Kogyo is used as a receptacle, the
GM-25K of this company is suitable for stuffing.
(3) The R8A66597FP generates a core power 1.5V from VCC 3.3V. An internal regulator makes 1.5V from
3.3V through the #19-pin and #20-pin of CN3 and outputs 1.5V to VDD pin. On the M3A-0040, 4.7uF and
0.1uF capacitors are mounted as smoothing capacitors for VDD.
(4) The interface power supply VIF is 1.8V or 3.3V.
(a) Short JP4 to “EXIOVcc” and supply 1.8V by the #25-pin and #26-pin of CN2 , when VIF is 1.8V.
(b) Short JP4 to “3.3V”, when VIF is 3.3V. In this case, power supply to VIF is the same as VCC.
(5) Use SD0-SD7 of CN2 when using split bus for DMA. SD0-SD7 can be used also as a general-purpose port.
(6) Processing for unused pin : Please refer to the R8A66597 datasheet, USB2.0 Dual Function Controller
R8A66597FP/DFP, for details.
5.2.2 VBUS control circuit
Note: When the peripheral device that connected to a USB connector is in an unusual state due to a short
circuit, or an overcurrent causes an overcurrent in VBUS, the overcurrent protection circuit of a USB
power switch IC turns on, and it turns the VBUS power supply off. But after turning off, current
around 0.4A continues flowing, and the USB power switch IC runs hot. Remove the unusual state
promptly for the sake of safety.
To start/stop supply VBUS to the peripheral device, the MCU should operate the R8A66597 to turn
on/off the VBUS output of the USB power switch IC (U2). When the USB power switch IC detects
overcurrent, it outputs a low pulse to the FLG output pin connected to the R8A66597FP, and it issues
an interrupt to MCU to notice the overcurrent state. Monitor the FLG output pin status and turn off
the VBUS output when the overcurrent state is detected by the R8A66597 control software.
Confirm that the USB device is in usual state before connecting.
(1) To supply 5V to VBUS of CN1:
(a) Apply 5V to CN4.
(b) Set JP6 to “HOST”.
(c) Output high signal from VBOUT0-pin by a R8A66597 control software.
(2) To supply 5V to VBUS of CN5
(a) Apply 5V to CN4.
(b) Output high signal from VBOUT1-pin by a R8A66597 control software.
Note: When the R8A66597 control software turn off VBUS supply from the USB power switch IC, VBUS is
not shutdown immediately but slowly because of 150uF capacitor.
5.2.3 Separate bus mode
Switch SW1 of the M3A-0040 board to “SEPA” when using as separate bus mode. Use A1-A6 of CN3 as
address bus.
5
5.2.4 Multiplex bus mode
Switch SW1 of the M3A-0040 board to “MULT” when using as multiplex bus mode. Use D1/AD1-D7/AD7 of
CN2 as address line share with data line. Keep open A1-A6 of CN3. Use #21-pin (A7/ALE) of CN3 as ALE.
5.3 Using M3A-0040 as a peripheral
When the M3A-0040 is operated as a peripheral controller, please pay attention to following notes:
(1) Set JP6 to "PERI"
(2) Connect a USB host, such as a PC to CN1
(3) To connect a USB host to CN1, an adapter is needed to convert the A-plug into the B-receptacle.
(4) CN5 is not available as a peripheral.
