1. Out of the Box
The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost and improved performance in powering state-of-the-art systems.
This page will guide the user through the process of setting up and using the RD33774PC3EVB board.
Working with the UJA1023-EVB (UJA1023 remote-controlled LIN I/O responder) requires a LIN commander board as additional hardware.
