3.1 Board Overview
The KIT33882EKEVB evaluation board is an easy-to-use circuit board that allows the user to exercise all the functions of the MC33882 Smart Six Output Switch (0.3
There are two ways to communicate with the evaluation board:
1. A PC communicates with the evaluation board through a FRDM SPI Dongle (FSD), connected to the PC's USB port, or
2. the microcontroller on the FRDM-KL25Z communicates with the evaluation board via microcontroller code.
The Freescale SPIGen 7.0.1 or higher program provides the user interface to the MC33882 SPI port and allows the user to send commands to the IC and receive statuses from the IC.
The Freescale CodeWarrior IDE allows the user to program the FRDM-KL25Z board with microcontroller code to send commands to the IC and receive statuses from the IC.

3.2 Board Features
This evaluation kit features the MC33882 Smart Six Output Switch (0.3 Ohm R Six Output Low-side Switch able to control system loads up to 1.0 A. The six outputs can be controlled via both serial peripheral interface (SPI) and parallel input control, making the device attractive for fault tolerant system applications. There are two additional 30 switches with SPI diagnostic reporting (parallel input control only).
The PCB contains a board to FRDM-KL25Z connector, which allows the FRDM-KL25Z to act as either a FSD or simply as an access to the KL25Z microcontroller. The board's main features are as follows:

3.5 Board Description
The analog part consists of the MC33882 chip controlling external loads. The digital part consists of the KL25Z controlling the MC33882 by SPI and I/Os.
This evaluation board is meant to demonstrate how the MC33882 can control eight low-side switches. Power is provided to the board via a VPWR/GND screw terminal (J1). Power can be disconnected from the board via an onboard switch
(SW1). If power is ON, LED D3 will light up. The VDD input of the device can only accept 5.0 V. However, on-board level shifters are provided to shift 3.3
The evaluation board provides a 20-pin connector (J2) to be used with the FRDM board. The connector J2 on the FRDM board connects to J2 on the evaluation board. The outputs of the switches are routed to independent 2-position screw terminals that have both one output and VPWR available (J3 through J10).
The evaluation board also includes several test points. A 16-pin row of pins allows access to all incoming signals. These sixteen signals are the following: MODE_B, IN4&IN5, IN2&IN3, IN0&IN1, CLK, MISO, MOSI, CS, IN0, IN1, IN2, IN3, IN4, IN5, IN6, and IN7. Eight loop test points provide access to the OUT0 through OUT7 signals. Two ground test points (GND1 and GND2) are available, as are three power test points (3V3, 5V, and VPWR).
V levels up to 5 V. Note the KL25Z FSD uses a 3.3 V microcontroller.
