(hereafter referred to as the EVB). The EVB is intended to provide a mechanism for easy
customer evaluation of the S32R294 microprocessor, and to facilitate hardware and software
development.
For the latest product information, please speak to your NXP representative.
The EVB is intended for bench / laboratory use and has been designed using normal
temperature specified components (+70°C).

2 EVB Features
The EVB provides the following features:
•MCU (soldered or through a socket)
•Single 12V external power supply input with one NXP FS8510 PMIC providing all of the
necessary EVB and MCU voltages; Power supplied to the EVB via a 2.1mm barrel style
power jack; 12V operation allows in-car use if desired
•Master power switch and regulator status LEDs
•Flexible MCU clocking options allow provision of an external clock via adaptor board
(MIPI-CSI0 connector) or 40MHz EVB clock oscillator circuit. Solder pads allow
selection between these external clocks
•Boot mode selection via switches on board
•Standard 14-pin JTAG debug connector and 34-pin Nexus Aurora connector
•10-pin Serial Interprocessor Interface (SIPI) connector
•Gb Ethernet Physical interface IC, with RJ45 connector
•Two MIPI-CSI2 connectors intended for use with TEF810X BEST3 RF front end board
(via a separate adaptor board X-S32R-TEF810X_ADPT)
•All MCU signals readily accessible at a port-

•FlexRAY interface
•3 CAN-FD interfaces:
o1x up to 8Mbps communication speed (CAN2)
o2x up to 5Mbps communication speed (CAN0, CAN1)
•UART to Micro USB interface
•2 user switches and 4 user LEDs, freely connectable
•256Mb (64MB) Serial NOR Flash memory
•64Kb EEPROM connected to MCU via I2C
•4*10-character LCD with DSPI interface (DSPI4)
•Liberal scattering of GND test points (surface mount loops) placed throughout the EVB
•User reset switch with reset status LED
NOTE
To alleviate confusion between jumpers and headers, all EVB 2-pin
jumpers are implemented as 2mm pitch whereas 3/4/6-pin jumper
andheaders are 0.1inch (2.54mm). This prevents inadvertently fitting
a jumper to a header.
CAUTION
Before the EVB is used or power is applied, please fully read the
following sections on how to correctly configure the board. Failure to
correctly configure the board may cause irreparable component,
MCU or EVB damage.

The EVB has been designed with ease of use in mind and has been segmented into functional
blocks as shown in Figure 1. Detailed silkscreen legend has been used throughout the board
to identify all switches, jumpers and user connectors.
Figure 1. EVB - functional blocks
3.1 MCU Power
The EVB requires an external power supply voltage of 12V DC, minimum 1.5A. This allows the
EVB to be easily used in a vehicle if required. The single input voltage is regulated on-board
using the NXP FS8510 PMIC to provide the necessary EVB and MCU operating voltages of
0.82V, 1.8V, 1.2V, 3.3V and 5V, and one backup 3.3V linear regulator for ENET IO and ENET
PHY.
