1. Purpose
This user's guide describes the use of the Demo Kit and gives the user a brief introduction to the AES
encryption/decryption algorithm. The current version of the firmware does not support remote mode, so it can only
be used in standalone mode without the Wireless Development Suite (WDS).

    Si4010 key fob on 316.66/433.9/868.30/917.00 MHz 4. Si4010 Key Fob Demo Description The AES demo utilizes the capabilities of the Si4010 key fob transmitter and the Si4355 EZRadio receiver in order to demonstrate a one-way secure link application. The Si4010 key fob as the transmitter sends radio packets with partially encoded content. At the receiver side an EZRadio receiver, the Si4355 chip receives the packet, then evaluates and decodes it.
