Getting Started with the FS45XX/FS65XX Evaluation Boards

Get Started

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 FS45xx/FS65xx evaluation boards.

2.2 Board Description

The KITFS4503CAEEVM, KITFS4508CAEEVM, KITFS6507LAEEVM, KITFS6522LAEEVM and KITFS6523CAEEVM are hardware evaluation tools supporting system designs based on NXP’s FS4500 and FS6500 product families. The kits allow testing the devices as an integral part of the overall system being developed. They provide access to all FS45xx and FS65xx functions (SPI, IOs) and support functional modes such as debug, normal, buck and boost.

2.3 Board Components

The primary components of the evaluation boards are the onboard MCUs. The boards include an FS45xx or FS65xx and provide full access to all features. An MKL25Z MCU USB controller enables access to the FS45xx/FS65xx through a USB connection.

In normal operation, configuration and monitoring applies to the onboard FS45xx/ FS65xx device. However, the board can be isolated from the onboard MCU. This allows connection to an off-board MCU without interference from the onboard device functions.

Number	Description
1	V_BAT connectors — use either jack connector or Phoenix connector to supply board
2	V_BAT switch — select VBAT from jack or from Phoenix connector
3	Ignition key — ignition key from car
4	LIN bus — LIN bus connector
5	CAN bus — CAN bus connector
6	I/Os — input and output from FS45XX/FS65XX (IO0, IO2, IO3, IO4, IO5, GND, V_KAM, VDDIO, V_BAT)
7	DBG mode select
8	Debug connector — could be used for debug purpose (CAN TX/RX, LIN TX/RX, SPI, Debug, FS0B, FS1B, INTB)
9	VCCA and VAUX selection — select 3.3 V/5.5 V configuration for VCCA and VAUX
10	MCU to FS65/FS45 connection — connects part or totality of signals between the KL25Z MCU and FS65XX/FS45XX
11	KL25 MCU — location of MCU and USB connector for control through FlexGUI
12	DFS mode select — enables or disables the deep fail-safe function
13	V_CORE selection — selects either 1.23, 3.3, or 5.0 V on VCORE DC-DC
14	Compensation network — selects either Network 1 or 2
15	Power supplies LED — visualizes regulator state (On or Off). The switches can disconnect LEDs
16	Power supplies — connector for power supplies (CAN_5V/VPRE/VCORE/VCCA/VAUX)
17	Buck/buck or boost selection — these jumpers select VPRE mode as a buck or buck or boost
18	FS45xx/FS65xx

Install Software

The kit is bundled with software allowing the user to interact directly with the onboard MCU during the development process. The boards contain an MKL25Z Kinetis processor pre-loaded with firmware controlling communication with the FS45xx/FS65xx MCU. A graphical user interface installed on a PC serves as the user interface to the evaluation board. When connecting the evaluation board to a PC through a USB cable, the following data exchanges are available:

SPI access (read and write) to FS45xx/FS65xx
ADC readout, connected to regulators
- VPRE
- VCORE
- VAUX
- VCCA
- CAN_5V
- MUX_OUT
- VDDIO
- VKAM
I/O readout, connected to IO_0 to IO_5
FS0B/FS1B readout
RSTB readout
CAN generated TX signal
LIN generated TX signal with loopback checking

Note that MCU connections to FS45xx/FS65xx can be fully isolated by removing related jumpers and switching off the related switch.

The software bundle also includes an XML file containing register descriptions for the FS45xx or FS65xx (depending on the evaluation board). This file must be installed for the GUI to work properly. In addition, an optional Excel file can be created to facilitate setting several registers at a click.

Configure the Hardware

The evaluation board must be connected to a PC through the USB port on the board. A 13.5 V power supply connects either to a jack connector (J4) or a Phoenix connector (J8). The evaluation board connects to an external load or another board through connector JP1.

CAUTION: To avoid damaging the board, the VBAT voltage must not exceed 40 V.

To configure the hardware and workstation, complete the following procedure:

With the power switched off, attach the DC power supply to either the Jack connector (J4) or the Phoenix connector (J8) on the evaluation board. There is no difference between the two connectors other than plug compatibility.
Attach a load or an external board through connector JP1.
Connect a USB cable from the evaluation board USB port (J33) to the USB port on a PC with the FlexGUI installed.
Turn on the DC power supply.
