1.Introduction
This user guide provides instructions to use the CYTVII-B-E-1M-176-CPU and CYTVII-B-E-176-SO
evaluation boards, collectively referred to as 'CPU board' in this document. This is an evaluation
platform for the CYT2B78CABES Traveo II device. The board can be used standalone for basic validation or in combination with the CYTVII-B-E-BB Traveo II baseboard (available separately from
Cypress). This document assumes that you will work with the combination (CPU board + baseboard), and provides guidance to use features of the evaluation platform. The Device Port Pin Connections on Baseboard and CPU board schematic used in this document is for CYTVII-B-E-1M-176CPU Rev C and Rev 1.0 boards and CYTVII-B-E-176-SO Rev C and Rev 1.0 boards only.
1.1Precautions and Warnings
The evaluation board must be handled by qualified personnel who are aware of the capabilities of
the boards. You must ensure your own safety arising from electrical hazards and other sources. You
must carefully handle the board, which is a delicate PCB, and ensure that it is not subjected to bending or other stresses.
The CPU board is shipped with a 12 V DC power adapter. This adapter can be plugged into the AC
mains supply anywhere in the world and is designed to receive 100-240 V AC V @ 50/60 Hz. While
powering the board, you must connect only the power adapter supplied with the evaluation board
and not any other part.

2.Overview
Figure 2-1 shows the CYTVII-B-E-176-SO board. Insert a Traveo II device into the IC socket
(marked in red) while the evaluation board is powered OFF.
Figure 2-1. CYTVII-B-E-176-SO Board
A variant of the CPU board (CYTVII-B-E-1M-176-CPU) is also available, where the Traveo II device
is soldered directly onto the PCB. Functionally, the CYTVII-B-E-1M-176-CPU and CYTVII-B-E-176SO boards are identical, except that the device can be easily replaced in the latter. Figure 2-3 shows
the CYTVII-B-E-1M-176-CPU mounted on baseboard.
Another variant of the CPU board is available which has 100-pin socket mounted on it. The CPU
board referred as a CYTVII-B-E-1M-100-SO board.
The CPU board is meant to be used along with a Traveo II baseboard (CYTVII-B-E-BB). The baseboard brings out all important interface connections such as CAN, LIN, SPI EEPROM, CXPI, and
Flexray, and can be used in conjunction with several CPU boards of the Traveo II family. Figure 2-2
shows the baseboard.

3.Operation
This section describes the operation of the CPU board and the baseboard. It is assumed that you
have connected the CPU board to the baseboard using the Samtec interface and inserted a TVII
device into the IC socket (applicable to SO boards only). The following method can be used to operate the CPU board and the baseboard.
1. For socketed CPU board, ensure that the device is inserted into the socket. Remove the four
screws on the socket using the screwdriver provided in the box and open the socket cover. If the
device is not present, place one carefully using a vacuum picker or a pair of tweezers.
2. Ensure that the pin 1 of the device is near the arrow mark (near C14) as shown in Figure 3-1.
You must also ensure that the angle of placing the device is such that the pins on all four sides of
the LQFP package match well with the socket pins. Align the device slightly if required.
Figure 3-1. Orientation of Device when Inserted in Socket
3. Put the socket cover and fix the four screws such that the socket cover tightly sits on the socket
base.
4. A 12V wall adapter board is supplied along with the CPU board. Connect the 12 V wall adapter to
the barrel connector marked “12V DC” on the CPU board. Connect its plug to a mains socket
using one of the four plug adapters provided in the white box (depending on the geographical
location and the socket type available).
5. Ensure that jumpers J23 (default 5 V: J23_1 and J23_2), J5, J6, J8, J10 (current measurement
jumpers) are inserted on the CPU board. You can select the 3.3 V power rails for CPU board by
shorting J23_2 and J23_2 as per their application or hardware setup.

Operation
6. Turn ON the mains supply to the wall adapter. Turn ON the switch SW1 on the CPU board. The
LED labelled PWR should light up.
7. Connect an appropriate programming tool to one of the programming interfaces (J17, J18, J19,
J20). Programming tool options are:
❐ GHS Trace on J20
❐ IAR I-jet on J18 or J19
❐ MiniProg3 on J19
8. Install the appropriate programming IDE on a PC. The programming IDE (GHS Multi, IAR EWB,
CYP, and so on) should be able to detect a device (read the device ID) and to load a firmware
HEX file (.sreg) into the device flash successfully.
As part of the release package, various firmware examples compiled in several programming
IDEs are available. Some examples use specific transceivers on the baseboard.
9. To start with, use the LED blink example provided with the release package to test the functioning of the board.
10. Connect a USB-mini cable to J12 and the other end to a PC. Open Tera Term or your preferred
terminal logging application and set the appropriate port and baud rate (typically 115,200 baud,
8, N, 1). Ensure that jumpers J11 and J13 are inserted on the CPU board. Some firmware examples provide data logs from the device or ask for user inputs over the terminal.

4.Connections and Settings
Ensure that the following jumpers are inserted on the baseboard to use each transceiver on the
baseboard with respective firmware examples which activate each functionality of the device.
1. CAN0.0 from the device uses the CAN0 and CAN6 transceiver on the baseboard. These transceivers are selectable through jumpers on baseboard. (connect jumpers J70, J71, J72 for CAN0
and J94, J109, J110, J105, J104, J106 and J103 for CAN6)
2. CAN0.1 from the device uses the CAN1 and CAN7 transceiver on the baseboard. These transceivers are selectable through jumpers on baseboard.(connect jumpers J66, J67, J68 for CAN1
and J97, J95, J101, J96, J98, J99 and J100 for CAN7)
3. CAN0.2 from the device uses the CAN2 and CAN8 transceiver on the baseboard. These transceivers are selectable through jumpers on baseboard.(connect jumpers J81, J82, J83 for CAN2
and J111, J112, J113, J115, J116, J118 and J117 for CAN8)
4. CAN1.0 from the device uses the CAN3 and CAN9 transceiver on the baseboard. These transceivers are selectable through jumpers on baseboard.(connect jumpers J76, J77, J78 for CAN3
and J114, J131, J125, J121, J122, J123 and J124 for CAN9)
5. CAN1.1 from the device uses the CAN4 transceiver on the baseboard (connect jumpers J91,
J92, J93)
6. CAN1.2 from the device uses the CAN5 transceiver on the baseboard (connect jumpers J86,
J87, J88)
7. LIN0 from the device uses the LIN0 transceiver on the baseboard (connect jumpers J58, J59,
J60, J63)
8. LIN1 from the device uses the LIN1 transceiver on the baseboard (connect jumpers J51, J52,
J53, J56)
9. LIN2 from the device uses the LIN2 transceiver on the baseboard (connect jumpers J37, J39,
J40, J43)
10. LIN3 from the device uses the LIN3 transceiver on the baseboard (connect jumpers J30, J31,
J32, J35)
11. LIN4 from the device uses the LIN4 transceiver on the baseboard (connect jumpers J22, J23,
J24, J27)
12. LIN6 from the device uses the LIN5 transceiver on the baseboard (connect jumpers J10, J16,
J17, J20)
13. EEPROM on the baseboard is enabled by connecting jumpers J47, J48, J49.
14. The user switch functionality is enabled by connecting jumper J102.
15. The potentiometer functionality is enabled by connecting jumper J89.
In addition, power is supplied to the baseboard by connecting jumper J80 in the '5V' position and
must always be connected. Once a specific functionality is chosen by connecting the jumpers listed
above, ensure that the appropriate firmware is loaded onto the device. Incorrect firmware can result
in port pins being configured incorrectly leading to bus contention and damage to hardware. For
example, if you connect jumpers related to CAN0.0, you must ensure that firmware configures the
related ports as CAN pins.
