Hardware Description

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 remote control and accessory simulator (SPI Gen) and

the parallel cable. This section describes the above three blocks.

4.1 Using the EVB

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 supply voltage on VBAT. Also that the thermal

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 and 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 presence 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 bolt.

5. For direct control of SA, put jumper, JINA, at position 2-3. For direct control of SB, put jumper, JINB, at

position 2-3. Disable watchdog placing a jumper at JFSI on position1-2 ( shorting 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.

Hardware Description

6. To use SPIGen, Go to the Windows Start menu, then Programs, then SPIGen, and click on the

SPIGen icon. The SPIGen "Generic SPI Generator" GUI will appear. Go to the File menu in the upper

left hand corner of the GUI, and select Open, then browse the CD to find and select the

33982_EVB_CONFIGURATION_FILE.spi file for the KIT33982CEVBE. Click Open, and SPIGen will

open a specifically configured SPI command generator for the KIT33982CEVBE. The configuration file

will set all parameters for SPI signals from the PC and provide a list of commands that may be sent to

the EVB.

7. To prepare the Evaluation card for SPIGen, Place jumper JINA, JINB, JRSTB, JWAKE to 1-2 position

8. To set up the 33982 device to read switch inputs the user may use the batch commands from the

"Send a Batch of Commands" tab. In the "Send a Batch of Commands" window, the Full Initialize batch

will appear. To send the batch of commands to the EVB, click the Send Once tab. To quickly evaluate

the EVB and device, simply click on the “Send one Command at a Time” tab, select the switch status

command from the Quick Commands list, and click the Send Continuous tab. The opening and closing

of switches may now be seen on the Word Received bits window field. Refer to the device data sheet

for detailed information on I/O communication and device operation.
