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 you through the process of setting up and using the RD33775ACNCEVB board.

2.2 Board Description
The RD33775ACNCEVB supports as a hardware reference design for centralized cell monitoring unit to communicate directly via CAN FD. The MC33665A populated on RD33775ACNCEVB is a gateway router that can route TPL messages from CAN FD to four different TPL ports.
The MC33775A is an ASIL D safety battery cell controller from NXP to monitor the lithium-ion cell voltages, temperatures and balance the lithium-ion cells. Four MC33775A battery cell controllers in RD33775ACNCEVB can monitor up to 56 lithium-ion cells.

3.1 Configure Hardware
RD33775ACNCEVB can be used in different setup configurations to check the performance of MC33665A and MC33775A. Figure 1 is a minimal hardware setup to check most of the functions and features built in RD33775ACNCEVB. BATT-14CEMULATOR is a slider-based emulator which can emulate the behavior of 14-cell battery pack. BATT-14EXTENDER which can convert the voltages from cell emulator to interface with four different battery cell controllers (max 14 cells each). Cell interface cables from RD33775ACNCEVB are compatible to BATT-EXTENDER and BATT-14CEMULATOR which can power up MC33775A battery cell controller (BCC) devices.
Contact NXP engineering team for using TPL AUTOWAKE function in RD33775ACNCEVB.
J25 connector can be used to power MC33665A and CAN FD communication to RD33775ACNCEVB. Electronic control unit (ECU) or
CAN tool can be interfaced to J25 for establishing CAN FD communication.
- To set up and communicate with RD33775ACNCEVB, check the data sheet of MC33665A and MC33775A
- Set the CFG0, CFG1, ID0_STB_OD, ID1, ID2 and ID3 based on ECU or CAN tools
- Based on test requirements, external MC33775A BCC devices can be connected to RD33775ACNCEVB
- Connect to
J30as extension to port 0 from fourth MC33775A - Connect to
J2as second daisy chain of MC33775A BCC devices to port 1 - External MC33771C/MC33772C can be connected to J2 as interface to daisy chain port 1 of MC33665A.
-
MC33771C/MC33772C BCC devices from NXP should not be connected to
J30. - Connect 12 V to BATT-14CEMULATOR and RD33775ACNCEVB after crosschecking the interface connections and boards based on test plan
