S32K148-T-BOX RDB BLOCK
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
I
2
S 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
S32K148-T-BOX RDB FEATURES
Support S32K148 with LQFP-144
or LQFP-176 pin package(default
mounted with LQFP-144 package)
SBC UJA1132 with 2 LIN physical
layers and 1 CAN physical layer
Integrate communication interfaces:
– 3x CAN with CAN-FD
– 3x UART(2 reused as LIN via SBC-
UJA113x)
– 1x 100M-base TX1 automotive
ethernet via TJA1101
– 1x I

S audio codec extend with
SGTL500 and support AVB
evaluation
Integrate 8MB QSPI NOR Flash
memory(MX25L6433F )
Provide T-BOX function module plugin
interfaces:
1 UART BLE module
1 UART GPS module
1 UART 4G communication module
2x user bottoms input
2x touch sensor input
1x RGB LED
1x Potentiometer
1x 3-axi accelerator(MMA8452Q) via
I

C
1x stand-alone RTC chip(PCA85063)
A 23-pin ECU connector, routing external
I/O signals including:
– 2x ADC input channels
– 2x HS PWM output channels
– 2x PWM input capture channels
– 3x CAN bus
– 2x LIN bus
– 1x 100M-base TX1 automotive
ethernet
Compatible with S32K148EVB:
– Arduino™ UNO footprint-compatible
with expansion “shield” support
– Can run all demo projects of SDK
Voltage supply options for 3.3V or 5V
