Chapter 1 Introduction
The RH850/F1x Application Board is part of the RH850 Evaluation Platform and
serves as a simple and easy to use platform for evaluating the features and
performance of Renesas Electronics 32-bit RH850/F1x microcontrollers. This
piggyback board Y-RH850-F1X-272PIN-PB-T2-V1 can be used as a standalone
board, or can be mated with a mainboard (e.g. Y-RH850-X1X-MB-Tx-Vx) for
extended functionality.
Main features:
Socket for mounting of device
Standalone operation of the board
Direct supply of device voltage (typ. 3.3V-5.0V)
Device programming capability
Device debugging capability
Pin headers for direct access to each device pin
Reset switch
MainOSC and SubOSC circuitry
Signal LEDs
Jumpers for device mode selection
Connectors to MainBoard
This document describes the functionality provided by the piggyback board and
guides the user through its operation.
This manual describes the following board revision:

2.2 Mounting of the device
The board is designed for use with the following devices:
RH850/F1KM-S4 272pin
RH850/F1KH-D8 272pin
The device must be placed inside the socket IC1. To insert the device, press
down the lid, align the #A1 pin of the device to the #A1pin of the socket, insert
the device inside the socket and release the lid.
For details regarding the operation of the microcontroller, refer to the
RH850/F1KH, RH850/F1KM User’s Manual.
2.3 Jumper configuration
The function of the board can be configured via jumpers. This chapter describes
the standard configuration, i.e. jumper setting for the intended devices. For the
supported function of the used device, please refer to the corresponding HW
user’s manual.
The table has the following meaning:
x-y: Connect the pins x and y; valid for 3-pin jumpers (e.g. JP10)
The pin #1 can be identified by a small circle in the vicinity of the
jumper
The jumper settings also are shown in this picture:

Figure 3 –Jumper setting overview
The green jumper JP12 for FLMDO0 always must be closed for a ‘normal’
(user mode and debug) operation of the device.
The red jumpers must be set for a “Voltage 1” (typ. +5.0V) operation of
the related device supply.
The blue jumper must be set for a “Voltage 2” (typ. +3.3V) operation of
the related device supply.
Note:
The RH850/F1KH-D8 device requires a supply voltage of 3.3V on its
REG1VCC pin.
The RH850/F1KM-S4 device requires the same supply voltage to be set
to REG0VCC and REG1VCC.
See the section ‘Electrical Characteristics’ in the device User’s Manual for further
details.
For jumper settings related to the device operation mode, refer to the
chapter 6.2.

Chapter 3 Power supply
3.1 Board power connection
For operation of the device, a supply voltage must be connected to the board.
Though a single supply voltage is sufficient for the operation of the device, two
(different) voltages can be supplied to the board.
Within this document the following voltages are considered as ‘typical’
connections:
Voltage1 = 5.0V
Voltage2 = 3.3V
The following connectors are available to supply those voltages:
Three 4mm ‘banana-type’ connectors:
- Two red connectors for voltages Voltage1 (CN54) and Voltage2 (CN17).
- A black connector for VSS connection (CN10).
Note: The three connectors are supplied with the board but not assembled.
The E1/E2 emulator that is used for debug purposes and flash programming
can also supply a single operating voltage (‘Dbg_Voltage’).
The voltage is programmable via the E1/E2 GUI as 3.3 or 5.0V (typ).
See the documentation of the E1/E2 and chapter 5 ‘Debug and
Programming interface’ for details.
In case the PiggyBoard is mounted on a MainBoard, the voltages Voltage1
and Voltage2 are supplied by the on-board regulators of the MainBoard.
NOTE: Do not supply any voltage directly to the PiggyBoard in case it is mounted
on the MainBoard.
For each of the two voltages, ‘Voltage 1 ‘ and ‘Voltage 2’, a green LED (LED1
and LED2) is available to signal that the related voltage is available on the
PiggyBoard.

3.2 Voltage distribution
The table shows the required device power supply pins and their function:
Device supply pin
Function
REG0VDD
REG1VDD
Supply for the device internal regulators for the digital
logic.
EVDD
Supply for ports.
BVDD
Supply for ports.
A0VREF
Supply for ports and analog functions of ADC0.
A1VREF
Supply for ports and analog functions of ADC1.
VDDIOF
IO supply voltage for the Mainboard.
For each of the above voltages, the voltage source can be selected from
Voltage1 (typ. 5.0V) or Voltage2 (typ. 3.3V) by the jumpers JP1-JP6, JP7,
respectively the jumpers JP0, JP9.
