Board features
The main features of FRDM665SPIEVB are:
• Request SPI
• Response SPI
• Onboard transformer isolation for TPL communication to BCC devices
• Configurable VIO voltage
• Configurable VDD5V from internal and external supply
• DIP switch for configuring the SPI of MC33665A to operate with or without crystals
• Reset switch for MC33665A
• LED display for the status of power
• Connectors to interface directly with S32K344EVB launchpad
• Connectors for external interface to general-purpose input/output (GPIO) and I2C-bus
Board description
The FRDM665SPIEVB allows the user to prototype and test all functions of the
MC33665A gateway router.
It can be stacked directly on the S32K344EVB. Different modes of SPI communication
can be established with MC33665A from K1 to K6 connectors. The FRDM665SPIEVB
can be supplied with 12 V at J6 connector or it can be powered directly from
S32K344EVB or EXT5V at J11. VDDC and VDDD can be selected by bridging one of the
positons in jumper J8 (Table 7) to select the 5 V. Bridging options jumper at J13 (Table 8)
makes it possible to select the VIO voltage of 3.3 V or 5 V or VIO of S32K344EVB.
S32K344EVB can be supplied with USB connection when connected to a PC.
SPI interface to external controller boards can be done with J7 for REQ SPI and J16 for
RSP SPI. Ensure the VIO of external controller board is the same as the VIO selected
with jumper J13. Single SPI or dual SPI modes can be selected by using jumpers at J14.
Populating all jumpers at J14 enables single SPI mode and depopulates jumpers at J14
for dual SPI mode. SW2 DIP switch can be used to select the CFG and ID configuration
for MC33665A. BCC devices can be connected to daisy chain ports 0 to 3 via connectors
J5, J12, J17, and J18.
Connector J1 gives the option to access the GPIO and I2C-bus pins of MC33665A.
