Chapter 1 Introduction

The RH850/E2x 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/E2x microcontrollers in a

BGA-292 package. The PiggyBack board (Y-RH850-E2X-292PIN-PB-T1 -V1)

can be used as a standalone board, or can be mated with a mainboard (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. 5V, 3.3V and 1.25V) enabling single

power supply and dual power supply

Device programming capability

Device debugging capability

Pin headers for direct access to each functional 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’s Manual.

2.2 Mounting of the device

The Y-RH850-E2X-292PIN-PB-T1-V1 PiggyBack board features a socket for

mounting of the device. All E2x in BGA-292 package do fit into the available

Enplas OTB-292(961RS)-0.8-019S-00 socket.

The device must be placed inside the socket IC1. To insert the device align the

device package #1pin with the #1pin of the socket. The #1pin of the socket is

marked with a circle near to the “IC1” label (see also red arrow in Figure 1). The

#1pin of the device is marked by a white triangle on the package (see white circle

in Figure 3).

Figure 3 Enplas OTB-292(961RS)-0.8-019S-00 Socket with Mounted Device

CAUTION: Please be careful with the placement to not damage the device.

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’ values:

Voltage1 = 5V

Voltage2 = 3.3V

Voltage3 = 1.25V

Direct voltage supply

Three different voltages can be supplied to the board.

The following connectors are available to supply those voltages directly:

Four 4mm ‘banana-type’ connectors:

- Three red connectors for voltages 5V (CN15), 3.3V (CN23) and 1.25V

(CN24).

- A black connector for ground (GND) connection (CN22).

Note: The four connectors are supplied with the board but not assembled.

For details about voltage distribution, refer to Chapter 3.2 ‘Voltage distribution’.

Supply by MainBoard

In case the PiggyBack board is mounted on a MainBoard, the 5V and 3.3V is

supplied by the on-board regulator of the MainBoard.

CAUTION: Do not supply 5V or 3.3V directly to the PiggyBack board in case it is

mounted on the MainBoard.

For each of the voltages, 5V, 3.3V and 1.25V a green LED (LED3, LED2 and

LED5, respectively) 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.

Board_VCC

Source for all devices (e.g. voltage regulator) on the

PiggyBack board

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 (JP4 –16 and JP23 –24).

The IO supply voltage for the Mainboard (VDDIOF) can be connected via

jumper JP17 to 5V or 3.3V, if the PiggyBack board is mounted on a

MainBoard.

VDD and EMUVDD can be powered either directly from the ‘banana-type’

connector (CN24) or by an on-board voltage regulator.

The source for the on-board voltage regulator, as well as the source for all

on-board devices (Board_VCC) needs to be configured via jumper JP30 to

either 5V or 3.3V.

The source for VDD is selectable by the jumper JP22. The jumper JP23 and

JP24 connect the voltage, configured by JP22 with the VDD and EMUVDD

pins.

Note: Although nominally 1.25V is used even as name in the schematic the

output of the voltage regulator IC19 is slightly increased to 1.28V (see

Chapter 11 ‘Schematic’). With this sufficient high voltage is applied, even in

case of any possible voltage drops.

Figure 4 Voltage Distribution on the PiggyBack Board

•The voltage supplied to the device pin W3 (marked "Ball_W3") must be

configured to either LVDVCC or E0VCC according to the device pinout.

Please check the device HW user’s documentation for more details.

For more details, please refer to Chapter 11 ‘Schematic’. For typical

configuration of the jumpers, please refer to Chapter 8 ‘Jumper Configuration’.

Chapter 4 Clock sources

External crystal oscillators for the device clock supply are provided with the

board.

4.1.1 MainOsc

A crystal or ceramic resonator can be mounted on socket X1.

A 20MHz and a 40MHz oscillator are supplied with the board.

The signals X1 and X2 are by default not connected to a pin header in order to

minimize disturbance on the resonator signal. If needed the signals can be

connected to CN5 (pins #24 and 26) via connecting with 0Ohm resistances R48

and R49. For details, please refer to Chapter 11 ‘Schematic’.

4.1.2 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 via resistor R38. The SG-8002CE is

neither mounted nor provided with the board. For details about the available

circuitry, refer to Chapter 11 ‘Schematic’. A resonator mounted on socket X1

must not be used in parallel to another clock source.

Chapter 5 Debug and Programming interface

The signal ‘EVTO’ from below connectors can be pulled up to ‘E0VCC’ via JP28.

Please refer to the documentation of the used tool, whether this is needed.

The signal ‘TRST’ from below connectors can be pulled up to ‘SYSVCC’ or to the

‘TRST’ line of the used tool via jumper JP31.

For typical configuration of the jumpers, please refer to Chapter 8 ‘Jumper

Configuration’.

5.1 14 Pin Debug Connector
