2 Important Notice

Freescale provides the enclosed product(s) under the following conditions:
This evaluation kit is intended for use of ENGINEERING DEVELOPMENT OR EVALUATION

PURPOSES ONLY. It is provided as a sample IC pre-soldered to a printed circuit board to make
it easier to access inputs, outputs, and supply terminals. This EVB may be used with any
development system or other source of I/O signals by simply connecting it to the host MCU or
computer board via off-the-shelf cables. This EVB is not a Reference Design and is not intended
to represent a final design recommendation for any particular application. Final device in an
application will be heavily dependent on proper printed circuit board layout and heat sinking
design as well as attention to supply filtering, transient suppression, and I/O signal quality.

The goods provided may not be complete in terms of required design, marketing, and or
manufacturing related protective considerations, including product safety measures typically
found in the end product incorporating the goods. D ue to the open construction of the product, it
is the user's responsibility to take any and all appropriate precautions with regard to electrostatic
discharge. In order to minimize risks associated with the customers applications, adequate design
and operating safeguards must be provided by the customer to mini mize inherent or procedural
hazards. For any safety concerns, contact Freescale sales and technical support services.

Should this evaluation kit not meet the specifications indicated in the kit, it may be returned within
30 days from the date of delivery and will be replaced by a new kit.

4 Hardware Description

The hardware in this evaluation kit includes an 33982 evaluation board. The evaluation board has three
major blocks: the circuit related to the 33982, the remo te control an d accessory simulator ( SPI Gen) and
the parallel cable. This section describes the above three blocks.

4.1 Using the EVB

Hardware Description

Figure 2. Setup for the 33982 EVB

Warning: Always wear Safety Glasses when working around electronic modules and when soldering.
Please remove of the capacitor, C8, when testing reverse sup ply voltag e on VBAT. Also that the therma l

resistance from junction to ambience of this PCB is approximately 25°/W.

1. The 33982 Evaluation board allows the customer to quickly evaluate features of the device with a simple
bench top setup. All switch inputs may be evaluated using the onboard switch banks or actual system
switches connected to the switch input edge connector.

2. Using a standard 25 pin Sub-D parallel port cable an d the enclosed SPIGen SPI Driver software, you
can use a personal computer to provide the Serial Peripheral Interface (SPI) communication with this
EVB.

3. Connect power supplies to the VBAT on the VBAT bolt. Connect GND, GNDBAT and +12 volt supply
on connector X, EVB's power terminal. On-board 5 volt regulator supply can be either supplied through
VBAT or +12V by selecting the jumper JSUPPLY. Make sure the voltages provided are in accordance
with the device data sheet and that the supply currents are sufficient to supply the attached loads. The
led L5V should light up indicating the pre sence of 5 volt regulated supply. Move IC from reset state by
shorting jumper JRSTB to 2-3 position (It shorts RSTB PIN to VDD).

4. Connect the desired loads to (e.g. relay coils, LEDs, or panel lamps) SB and SA bo lt.

5. For direct control of SA, put jumper , JINA, at position 2-3. For direct contr ol of SB, put jumper, JINB, at
position 2-3. Disable watchdog placing a jumper at JFSI on position1-2 ( shortin g the PIN to GND) and
not placing jumper on JWAKE. (Shorting PIN to GND). Led LA and LB should light up if jumper are
placed on JLA and JLB.
