Chapter 1 Introduction
The RH850/P1M-C 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/P1M-C microcontrollers in a
144pin QFP package with 0.4mm pin pitch. The PiggyBack board (Y-RH850-
P1XC-144PIN-PB-T1-V1) can be used as a standalone board, or can be mated
with a mainboard (e.g. Y-RH850-X1X-MB-T1-V1) for extended functionality.
Main features:
Socket for mounting of device
Standalone operation of the board
Direct supply of device voltage (typ. 3.3V and 1.25V) enabling single power
supply (eVR) and dual power supply (DPS)
Device programming capability
Device debugging capability
Pin headers for direct access to each device pin
Reset switch
MainOSC circuitry
Connectors to MainBoard
Operating temperature from 0°C to +40°C
This document describes the functionality provided by the PiggyBack board and
guides the user through its operation.
For details regarding the operation of the microcontroller, refer to the
corresponding User Manual.

2.2 Mounting of the device
The board is designed for use with the following device:
RH850/P1M-C in 144pin QFP package with 0.4mm pin pitch
The device must be placed inside the socket IC1. To insert the device, press
down the lid of the socket, align the #1 pin of the device to the #1 pin of the
socket, insert the device into the socket and release the lid.

Chapter 3 Power supply
3.1 Board power connection
For operation of the device, a supply voltage must be connected to the board.
There are several possibilities to power the device.
Within this document the following voltages are considered as ‘typical’
connections:
Voltage1 = 3.3V
Voltage2 = 1.25V
Direct voltage supply
Two different voltages can be supplied to the board.
The following connectors are available to supply those voltages directly:
Three 4mm ‘banana-type’ connectors:
- Two red connectors for voltages Voltage1 (CN13) and Voltage2 (CN14).
- A black connector for ground (GND) connection (CN12).
Note: The three connectors are supplied with the board but not assembled.
For details about voltage distribution, refer to Chapter 3.2 ‘Voltage distribution’.
Supply by E1 emulator
The E1 emulator that is used for debug purposes and flash programming can
also supply a single operating voltage (‘Dbg_Voltage’). This voltage is connected
to Voltage1.
See the documentation of the E1 and Chapter 5 ‘Debug and Programming
interface’for details.
Supply by MainBoard
In case the PiggyBack board is mounted on a MainBoard, the voltage Voltage1 is
supplied by the on-board regulator of the MainBoard.
CAUTION: Do not supply Voltage1 directly to the PiggyBack board in case it is
mounted on the MainBoard.
For each of the voltages, Voltage1 and Voltage2 a green LED is available to
signal that the related voltage is available on the PiggyBack board. The
corresponding LEDs are placed directly beneath the connectors of the related
voltage.

of their function, please refer to the user documentation of the corresponding
device:

VDDIOF
IO supply voltage for components located on a
connected mainboard.
The following figure shows the configurable voltage distribution on the PiggyBack
board.

All power supply lines can be interrupted by jumpers. This provides the
possibility to measure the current consumption of each individual power
domain of the device.
The IO supply voltage for the Mainboard (VDDIOF) can be connected via
jumper JP1 to Voltage1, if the PiggyBack board is mounted on a MainBoard.

In case of a DPS device, VDD can be powered either directly from the
‘banana-type’ connector (Voltage2 –CN14) or by an on-board voltage
regulator. Thereby even a DPS device can be operated with one single
voltage supply (Voltage1).
The source for VDD is selectable by the jumper JP11. The jumper JP12
connects the voltage, configured by JP11 with the VDD pins.
CAUTION: Jumper JP12 must not be connected in case of an eVR device. In this
case the connected pins function as VCL pins and must not be supplied with a
voltage.

Chapter 4 Clock sources
One external crystal oscillator for the device clock supply is provided with the
board.
4.1 MainOsc
A crystal or ceramic resonator can be mounted on socket X1.
A 16Mhz oscillator is supplied with the board.
4.2 Programmable Oscillator
It is possible to mount a programmable crystal oscillator on the PiggyBack board
at OSC1. The available footprint and circuitry is designed for a SG-8002CE
programmable crystal oscillator from Epson Toyocom. The output from this
oscillator can be connected to port X1 of the device via jumper JP13. The SG-
8002CE is neither mounted nor provided with the board. For details about the
available circuitry refer to Chapter 10 ‘Schematic’. A resonator mounted on
socket X1 must not be used in parallel to another clock source.
