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.
1.1 Kit Contents and Packing List
- Assembled and tested evaluation board/module in antistatic bag
- Three cell terminal cables
- Transformer physical layer (TPL) cable
1.2 Additional Hardware
In addition to the kit contents, the following hardware is necessary or beneficial when working with this kit:
- A 4-cell to 18-cell battery pack or a battery pack emulator, such as BATT-18EMULATOR
- FRDMDUALK3664EVB (EVB for MC33664A) with the S32K3X4EVB-T172 (S32K3X4 EVB) to interface with a PC
- For the evaluation setup, a graphical user interface, EvalGUI 7, is available in Secure Files at this link: MC33775A Evaluation GUI V7

This section gives guidance on how to set up and run the RD33774PC3EVB evaluation board and GUI.
3.1 Battery Emulator Connection
A minimum of four cells and a maximum of 18 cells can be monitored by one MC33774ATP. NXP provides an 18-cell battery emulator board, BATT-18EMULATOR. This board provides an intuitive way to change the voltage across any of the 18 cells of an emulated battery pack. The board RD33774PC3EVB can be connected to an 18-cell battery emulator board using the connectors J1_1, J1_2 and J1_3, with the provided supply cable. See Figure 2.
3.2 TPL Communication Connection
In a high-voltage isolated application with a daisy-chain configuration, up to 63 RD33774PC3EVB boards may be connected.
The TPL connections use the COMM connectors J1 and J2 of the FRDMDUALK3664EVB and J2_1 and J2_3 of the RD33774PC3EVB.
