mikroBUS socket connector J7. It allows a SPI
connection between the target MCU and click
board plugged into the mikroBUS socket.
Slave select 1
Bidirectional voltage translator U24
(74AVC4TD245BQ). It supports a USB-to-SPI
bridge between MCU-Link and the target MCU,
by shifting voltage levels of signals between the
two devices from 3.3 V to 3.3/1.9 V and vice
versa. The USB-to-SPI bridge can be disabled
(so that the target MCU HS SPI port can be used
for other purposes) by shorting jumper JP57 (not
populated on the board).
MCU-Link target (LPC55S69). The USB-to-SPI
bridge between MCU-Link and the target MCU
can be used for debugging the target MCU
(slave) from MCU-Link (master).
8 Mbit SPI NOR flash memory (U10) (not
populated on the board). Supported part number
is MX25R8035FM2IL0.
If the SPI NOR flash memory is attached,
it is powered up by shorting jumper JP34
(not populated on the board). Using this
connection also requires disabling the USB-to-
SPI bridge between MCU-Link and the target
MCU by shorting jumper JP57 (not populated on
the board).
Slave select 3
Motor 2 c Arduino socket connector J92.
It allows a SPI connection between the target
MCU and board/module attached to the socket.
2.8 CAN interface
The target MCU has a controller area network flexible data (MCAN) controller, which supports CAN flexible data-rate (FD). The
LPC55S36-EVK board allows communication with MCAN controller through a high-speed (HS) CAN transceiver, which drives
CAN signals between MCAN controller and a physical two-wire CAN bus that terminates at a DB9 connector.
The figure below shows the CAN diagram of the LPC55S36-EVK board.
