Hardware user manual for FRDM665SPIEVB
4 Getting to know the hardware
4.1 Kit overview
The FRDM665SPIEVB serves as a hardware evaluation tool in support of the MC33665A
device of NXP. The MC33665A is a gateway router that can route TPL messages from
a microcontroller to four different TPL ports. It is designed for use in both automotive
and industrial applications. The device can route both TPL2 and TPL3 messages.
FRDM665SPIEVB is an ideal board for rapid prototyping of MC33665A for SPI interface
to MCU.
FRDM665SPIEVB supports an SPI for both requests (REQ) and responses (RSP).
Differential communication to daisy chain devices can be established with four different
ports.
