1 Introduction

1.1 Purpose of Document

This document provides instructions on how to use the features of the VORAGO PEB1

evaluation kit (EVK) and provides a working platform for software development for either the

VA41620 or VA41630 MCUs from VORAGO. The VA41630 has an integrated, internal 2Mb NVM

memory device that contains the user’s program loaded into the MCU at boot. In all other

ways, the VA41620 and VA41630 MCU devices are identical.

1.2 Overview of Hardware and Software components

The PEB1 evaluation kit comprises three printed circuit boards.

• The PEB1 MCU board (top board)

• The PEB1 GPIO board

• The PEB1 EBI/Ethernet board

1.3 Key components included on the PEB1 evaluation kit (subject to change depending

on availability).

• The PEB1 MCU board

o VORAGO VA416x0 MCU

o IDT 501MLFT PLL clock multiplier

o Cypress FM25V20A FRAM

o ST Micro STM32F103C4 MCU0

o Three voltage regulators

• The PEB1 GPIO board

o Two TI isolated CAN transceivers

o Cypress FM25V20A FRAM

o ST Micro LIS2DE12TR accelerometer

• The PEB1 EBI/Ethernet board

o Two TI isolated CAN transceivers

o Microchip KSZ8041TL Ethernet PHY

o Cypress CY7C1041GE SRAM

o Cypress FM22L16 FRAM

1.3.1 The PEB1 MCU board

The PEB1 MCU board includes a SEGGER JTAG Probe, the J-Link OB interface. A separate JTAG

debug pod is not required however a dedicated connector is provided if a different tool is

preferred. SEGGER Microcontroller is VORAGO’S preferred supplier of hardware and software

VA41620/VA41630 Evaluation Board User’s Manual

development tools. The J-Link OB allows the board to be connected directly to the USB port of

a PC to allow:

- Power supplied from the USB 5V source supply

- JTAG communications for debug and programming

- Terminal communications to allow data transfer between a PC terminal window and

the VA416x0 MCU.

A block diagram of the MCU evaluation board is shown in Figure 1. The MCU evaluation board

conveniently stacks on to resource boards for maximum development flexibility. If compact size

is preferred, the MCU board may be used standalone with full JTAG and includes a UART for

background communication.

Figure 1 - Block diagram of PEB1

1.3.2 The PEB1 GPIO board

The PEB1 GPIO board provides additional connectivity to the VA416x0 MCU. Access to all 104

GPIO pins are available on the various convenient headers. Header pins located on the GPIO

board as well provide access to integrated board resources, ADC inputs, DAC outputs, I2C

interfaces, CAN interfaces with transceivers, and a connector for a SpaceWire interface. An

accelerometer is provided on the board as well, with access via one of the three I2C interfaces.

An external SPI accessible FRAM device is also included on the board. Four PMOD connectors

are available for the I2C, UART, and SPI peripherals.

1.3.3 The PEB1 EBI/Ethernet board

The PEB1 EBI/Ethernet board provides additional connectivity to the VA416x0 MCU. To suit

another example of port expansion, covering a different set of peripherals, the External Bus

Interface (EBI)/Ethernet interface board provides access to 41 GPIO pins as well as access to

ADC inputs, DAC outputs, I2C interfaces, CAN interfaces with transceivers, and a connector to

the SpaceWire interface. Two high speed parallel memory devices, an SRAM and a FRAM are

included. The VA416x0 Ethernet peripheral is connected to an external Ethernet physical layer

transceiver device and an RJ-45 connector.

1.5 Connector pin assignment table for MCU board

The schematics for the three boards are included in PEB1 download package. To assist with

quickly finding which pins are tied to the various connectors on the board, the following set of

tables are provided.

Table 1 - PEB1 MCU Board Connector designations

The PLL clock source provided on the MCU board is clocked with a 20MHz crystal oscillator. The

default setting on the board will provide a 40MHz clock input to the MCU. JP8 pins 7 and 8 are

tied together. Additional jumpers placed on JP8 can configure a different clock frequency for

the MCU as follows.

Table 2 - PEB1 MCU Board Connector designations for clock selection

1.6 Materials List

• PEB1 evaluation boards – Programmed with demonstration program

• 36” Micro USB cable

• Insert card with component placement picture and URL

• 10 jumpers and several wires

1.7 Board connectivity

This photo shows the PEB1 MCU board mounted onto the PEB1 GPIO board. The connection

between these two boards is made by aligning the plastic pins on the lower board with the

holes on the upper board. Similar connectivity is achieved with the PEB1 MCU board and the

PEB1 EBI/Ethernet board.

1.8 Connector pin assignment table for GPIO board

The GPIO board has two large 0.1in headers, labeled J21 and J22. The connections to the MCU

are as follows.
