To our customers,
Old Company Name in Catalogs and Other Documents
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.

Chapter 2. Purpose
This RSK is an evaluation tool for Renesas microcontrollers.
Features include:
• Renesas Microcontroller Programming.
• User Code Debugging.
• User Circuitry such as Switches, LEDs and potentiometer(s).
• User or Example Application.
• Sample peripheral device initialisation code.
The RSK board contains all the circuitry required for microcontroller operation.

Chapter 3. Power Supply
3.1. Requirements
This RSK operates from a 3V to 5V power supply.
A diode provides reverse polarity protection only if a current limiting power supply is used.
All RSK boards are supplied with an E8 debugger. This product is able to power the RSK board with up to 300mA. When the RSK is
connected to another system then that system should supply power to the RSK.
All RSK boards have an optional centre positive supply connector using a 2.1mm barrel power jack.
Warning
The RSK is neither under nor over voltage protected. Use a centre positive supply for this board.
3.2. Power – Up Behaviour
When the RSK is purchased the RSK board has the ‘Release’ or stand alone code from the example tutorial code pre-programmed into the
Renesas microcontroller. On powering up the board the user LEDs will start to flash. After 200 flashes, or after pressing a switch the LEDs
will flash at a rate controlled by the potentiometer.

6.2. LEDs
There are six LEDs on the RSK board. The green ‘POWER’ LED lights when the board is powered. The orange BOOT LED indicates the
device is in BOOT mode when lit. The four user LEDs are connected to an IO port and will light when their corresponding port pin is set low.
Table 6-2, below, shows the LED pin references and their corresponding microcontroller port pin connections.

6.3. Potentiometer
A single turn potentiometer is connected to AN4 (P0.3) of the microcontroller. This may be used to vary the input analogue voltage value to
this pin between AVCC and Ground.

6.4. Serial port
The microcontroller programming serial port 1 is connected to the E8 connector. This serial port can optionally be connected to the RS232
transceiver as well by fitting option resistors. The connections to be fitted are listed in the table 6-3.

Table 6-3: Serial Port settings
A Secondary serial port is connected to the application headers. This is shared with the LEDs.
6.5. LCD Module
A LCD module is supplied to be connected to the connector J8. This should be fitted so that the LCD module lies over J1. Care should be
taken to ensure the pins are inserted correctly into J8.The LCD module uses a 4 bit interface to reduce the pin allocation. No contrast
control is provided; this is set by a resistor on the supplied display module. The module supplied with the RSK only supports 5V operation.
Table 6-4 shows the pin allocation and signal names used on this connector.

6.7.Oscillator Sources
A crystal oscillator or ceramic resonator is fitted on the RSK and used to supply the main clock input to the Renesas microcontroller.
Table 6-6: Oscillators / Resonators
details the oscillators that are fitted and alternative footprints provided on this RSK:
Component
Resonator (X1) Fitted 20 MHz
Crystal (X2) Not Fitted 20 MHz (HC/49U
package)
Table 6-6: Oscillators / Resonators
6.8.Reset Circuit
The CPU Board includes a simple latch circuit that links the mode selection and reset circuit. This provides an easy method for swapping
the device between Boot Mode, User Boot Mode and User mode. This circuit is not required on customers boards as it is intended for
providing easy evaluation of the operating modes of the device on the RSK. Please refer to the hardware manual for more information
on the requirements of the reset circuit.
The Reset circuit operates by latching the state of the boot switc h on pressing the reset button. This control is subsequently used to
modify the mode pin states as required.
The mode pins should change state only while the reset signal is active to avoid possible device damage.
The reset is held in the active state for a fixed period by a pair of resistors and a capacitor. Please check the reset requirements carefully
to ensure the reset circuit on the user’s board meets all the reset timing requirements.
11
Chapter 7. Modes
The RSK supports Boot mode and Single chip mode.
Details of programming the FLASH memory is described in the R8C/13 Group Hardware Manual.
7.1. Boot mode
The boot mode settings for this RSK are shown in Table 7-1: Boot Mode pin settings below:
MODE LSI State after Reset End
Low Boot Mode
Table 7-1: Boot Mode pin settings
The software supplied with this RSK supports Boot mode using an E8 and HEW only. However, hardware exists to enter boot mode
manually, do not connect the E8 in this case. Press and hold the SW1/BOOT. The mode pin is held in its boot state while reset is pressed
and released. Release the boot button. The BOOT LED will be illuminated to indicate that the microcontroller is in boot mode.
When neither the E8 is connected northe board is placed in boot mode as above, the Mode pin is pulled high by a 100k resistor.
When an E8 is used the Mode pin is controlled by the E8.
7.2. Single chip mode
Because the Mode pin is pulled high, this RSK will always boot in Single Chip mode when the E8 is not connected and the boot switch is not
depressed. Refer to R8C/13 Group Hardware Manual for details of Single chip mode.
MODE LSI State after Reset End
High Single Chip Mode
Table 7-2: Single Chip Mode pin settings

Chapter 8. Programming Methods
The board is intended for use with HEW and the supplied E8 debugger. Refer to R8C/13 Group Hardware Manual for details of
programming the microcontroller without using these tools.

Chapter 10.Code Development
10.1. Overview
Note: For all code debugging using Renesas software tools, the RSK board must be connected to a PC USB port via an E8. An E8 is
supplied with the RSK product.
10.2. Mode Support
HEW connects to the Microcontroller and programs it via the E8. Mode support is handled transparently to the user.
