MCU Applications Engineering
Note:
* Connect an external power supply to these points to power the board when not using the ICD.
** Use this jumper (JP2) when connecting batteries or an external supply to power to the add-on
on-board voltage regulator. The bottom side of the board can be populated with a voltage
regulator circuit and battery holder for stand-alone operation. See Appendix G for more
information.
5.1.1 R8C/Tiny Series of Microcontrollers
The R8C/Tiny Series of 16-bit single-chip, flash microcontroller (MCU) is available in several
configurations of peripheral functions and features. The Hardware Manual for the R8C/17 group
of microcontrollers can be found on the C:\RENESAS\SKP8CMINI17\Docs folder of your PC
under the filename ‘ r8c17_hardware_manual_revx.x.pdf ’ after SKP software installation or
from the Start menu (Start > All Programs > RENESAS-TOOLS > SKP8CMINI17 > Document
Descriptions).
5.1.2 Block Diagram
The Mini R8C Board incorporates an R5F21174SP (20 pin SSOP) from the R8C/17 group of
microcontrollers. Figure 5-2 shows the Mini R8C Board block diagram.
