DIAGRAM
To achieve the maximum flexibility to be
T-BOX/GP-ECU Ref-Design/S32K148 EVB:
 BLE, GPS and 3G/4G select
independent Module and connect with
S32K148 via UART
 Add QSPI Nor-Flash, standalone
RTC and 3-aix Accelerator for T-Box
functions
 Extend a 100M-base TX1 automotive
ethernet via TJA1101 for both T-Box
connection and AVB evaluation (plus a
I2S audio Codec )
 SBC provides 5/3.3V power supply for
S32K148 and other onboard modules
and also expends 1 CAN and 2 LIN bus
 Select TJA1044 with SO-8 and TJA1043
with HVSON14 package to compatible
with Stinger
 Use a 23-pin ECU connector to route
all CAN/LIN/ENET bus and extend 2x
HS output, 2x PWM input capture and
2x Analog Input, enable it to work as a
GP-ECU

USING ETHERNET AND QSPI
IMPORTANT OBSERVATION
The S32K148 is the only member of the
family able to use ethernet and QuadSPI.
However, these interfaces are mutually
exclusive so only one of them can be
used at a time. In order to use either
Ethernet or QuadSPI, user must follow
an specific resistor configuration. The
default configuration of the board is to
be used for ethernet communication.
CHANGE 0Ω CONFIGURATION
RESISTORS TO REUSE BETWEEN
ENET AND QUADSPI
 For S32K148 T-BOX RDB, some ENET
and QuadSPI data lines are shared
from the MCU, each interface is
separated by two 0 Ω resistors
 By default the ENET data lines are
enabled
 User can change the 0Ω configuration
resistors to enable and use QuadSPI:
S32K148 shared PIN Configuration resistor Description
PTD7 R161 (Default) ENET: MII_RMII_TXD1
R162 QuadSPI: QSPI_A_IO1
PTC2 R177(Default) ENET: MII_RMII_TXD0
R178 QuadSPI: QSPI_A_IO3
PTC3 R196 (Default) ENET: MII_TX_ER
R203 QuadSPI: QSPI_A_CS
PTD10 R178 (Default) ENET: MII_RX_CLK
R179 QuadSPI: QSPI_A_SCK
PTD11 R194 (Default) ENET: MII_RMII_TX_CLK
R195 QuadSPI: QSPI_A_IO0
PTD12 R190 (Default) ENET: MII_RMII_TX_EN
R192 QuadSPI: QSPI_A_IO2

S32K148-T-BOX RDB
Out-of-the-Box Setup
POWER UP THE BOARD AND
DEBUGGER CONNECTION
 The S32K148 T-BOX RDB powers from
external +12V power supply via the
23-pin ECU connector with the wiring
harness. If no 23-pin ECU connector
wiring harness available, the board be
powered by J31-8 (GND) and J31-1
(+12V)
Note: There is no embedded debugger
(e.g. OpenSDA) on the RDB, so debug
is done using PEMicro U-Multilink/FX
through J12 with a mini-20 pin cable on
debugger’s port F
 After power on, the D10, D11 and D12
on the left up corner of the board will
light on
 With Connecting the U-Multilink
debugger to PC, its USB and TGTPWR
LED will be lighted on
