1 Introduction
The CC900 single chip RF transceiver includes many features and great flexibility,
which makes the chip suitable for a very large number of applications and system
requirements. The CC900DB Demonstration Board is designed to demonstrate how the
CC900 chip can be used in a simple two-way remote control. Full documentation is
provided for this module, including schematic, layout and micro-controller code, this
design will be a starting point and make it very easy for the user to evaluate transceiver
performance, and in a short time develop his own applications based on this reference
design.
The kit includes two CC900DB Demonstration Boards with a complete CC900
transceiver, micro-controller, integrated PCB antenna and battery. The Demonstration
Boards are pre-programmed to serve as a simple demonstrator. By pushing the “ON”
button, the device will be awakened. Both modules should be awaked before a
transmission takes place. A transmission is initiated by pushing the “TX” button. A
blinking sequence of approximately 2 seconds duration is then transmitted and shown on
the receivers LED. The same “message” is returned from the receiver to the initial
transmitter and shown on its LED as an “acknowledge”. The modules will enter sleep
mode after being left without operation for one minute.
Technical features:
-10 dBm RF power
Up to 30-meter range (depending on antenna orientation)
Small integrated shorted-stub antenna
<1uA power-down current in sleep mode
3.6V Lithium battery supply (~1000mAh)
SmartRF
®
Studio makes it possible to reconfigure the CC900DB system parameters by
inserting the Demonstration Board into the CC900EB Evaluation Board edge connector.
It is also possible to upgrade the Demonstration Board with new micro-controller
program code from SmartRF
®
Studio, see the SmartRF
®
Studio user manual for details.
The CC900DB is also designed to work together with the Atmel AVR micro-controller
STK500 development board, the in-system programmer ATAVRISP or similar. At the
rear side of the board there is a 10 pin connector foot-print which fits a 10-pin ISP cable.
This user manual describes how to use the Demonstration Board and how to use it to
develop your own applications. You will also find a detailed description of the circuit
board and the micro-controller code.
