The FRDM665SPIEVB serves as a hardware evaluation tool in support of the MC33665A device (SPI variant) from NXP. The MC33665A is a gateway router that can route TPL messages from the microcontroller (MCU) 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. The FRDM665SPIEVB is an ideal board for rapid prototyping of the MC33665A for SPI interface to a MCU. Onboard TPL interface for four TPL ports has transformer isolation.
