Si4012 PROGRAMMING GUIDE
1. Introduction
This document gives an overview of how to configure and use the Si4012 radio transmitter and provides several
simple software examples.
The Silicon Laboratories’ Si4012 is a fully integrated, crystal-less CMOS high-data rate RF transmitter designed for
the sub-GHz ISM band. This chip is optimized for battery powered applications requiring low standby current and
high output transmit power.
The following operation examples are covered in the programming guide:
How to configure the Si4012
How to use the Si4012 transmitter for packet transmission in FIFO mode
How to measure battery voltage
The latest example source codes are available on the Silicon Labs web site: www.silabs.com.
2. Hardware Platform
The source codes are provided for the LCD Base Board hardware platform that is part of the 4012-LCDK1W-434
and the 4012-LCDK1W-915 Si4012 EZRadio One Way Link Development Kits.The LCD Base Board platform is a
demo and development platform for the EZRadio family of RF chips. It consists of an LCD Base Board and
interchangeable RF Pico Boards.
