1. Introduction

The Silicon Labs Wireless Product Software Development Board, MSC-DBSB8, is designed to help engineers

develop code for the Silicon Lab's EZRadio® and EZRadioPRO™ wireless products using the Silicon Labs

C8051F9xx microcontroller platform.

The C8051F9xx Wireless Software Development Board (MSC-DBSB8) is designed for code development. A

second platform, the WDS Loadboard, may also be purchased allowing for exhaustive RF lab based testing. The

Loadboard can be bought under the part number MSC-DKLB2 but also within the ISM-DK3 kit.

Software Development Board (SDB)

Figure 2. MSC-DBLB2 (Not Included)

Testing Platform for controlled Lab Tests

(Loadboard)

Both boards come with the Silicon Labs standard 40-pin socket for connecting standard EZRadio® and

EZRadioPRO™ evaluation testcards such as the Si4432-DKDB1. The onboard C8051F930 comes preloaded with

sample firmware to demonstrate a packet-based wireless link between two systems.

The MSC-DBSB8 C8051F9xx software development board includes:



One 40-pin socket for EZRadio and EZRadioPRO testcards

C8051F930 microcontroller preloaded with demonstration software

Standard debug connector for Silicon Labs C8051 programming and debugging

4 buttons and 4 LEDs for custom purposes

LCD display for setup parameters and information display

RS232 interface via a 9-pin DSUB male connector

USB type B connector with Silicon Labs CP2102 USB > Serial Converter onboard

On board 3.3 V PSU

5 x 19 through hole breadboard area for customer's application
