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 Ohm R
DS(on)
) with SPI and Parallel Input Control.
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.

Board Features
This evaluation kit features the MC33882 Smart Six Output Switch (0.3 Ohm R
DS(on)
) with SPI and Parallel Input Control, which is a Smart
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 mA low-side
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:
•
Output terminals for loads
•
Test points for various inputs, outputs, and SPI signals
•
FSD connector
