CAN
controller
Voltage translators CAN transceiver Connector
MCAN Two voltage translators U25 and
U26 (74LVC1T45GW,125). U25
and U26 shift voltage levels of
signals between the target MCU
and HS CAN transceiver from
3.3/1.9 V to 5 V and vice versa.
High-speed CAN transceiver U9 (NXP TJA1044GT),
which is designed for high-speed CAN applications
in the automotive industry, providing the differential
transmit and receive capabilities to a CAN protocol
controller. It converts and sends analog data from
CAN bus lines to the target MCU as digital data, and
converts and sends digital data from the target MCU
to the CAN bus lines as analog data.
DB9 male
connector J19. It
allows external
CAN connection
with the CAN bus.
Table 17. LPCXpresso55S36 CAN connections
Jumpers JP23 and JP24 are used to enable/disable high-level CAN bus line (CANH) and
low-level CAN bus line (CANL), respectively.
Jumper JP48 is used to select the target MCU input pin for the MCAN controller. Jumper
JP49 is used to select the target MCU output pin for the MCAN controller.
2.9 I3C interface
The MIPI Alliance improved inter-integrated circuit (MIPI I3C) brings major improvements
in use and power over I2C, and provides an alternative to SPI for mid-speed applications.
The target MCU has an I3C module, which is used as an I3C master for devices (I3C
slaves) connected to I3C bus on the LPCXpresso55S36 board.
The I3C and SWD signals are shared on the LPCXpresso55S36 board. While using I3C,
it is recommended to short jumper JP27 to isolate MCU-Link from driving the shared
signals.
The figure below shows the I3C diagram of the LPCXpresso55S36 board.
