Market Acceptance and Trends
 Modern RF devices lower design barriers




RF becoming easier to add to existing products—wider RF adoption
Fuller featured radios available: (antenna tuning, AFC, etc)
RF data-links costs are dropping
Lightweight MCU encryption algorithms
 Open Standard: AES128, TEA, XXTEA
 Proprietary: Keeloq®, Hitag, AVR411
 Lower barriers increasing wireless applications
 Game controller, sensors, data logging, etc.
 Large and established one-way link applications today
 RKE, remote control, sensors
 Increasing trend towards two-way links
 Confirm communication, reduced power consumption, increased
noise immunity

 Larger MCU memory requirement
 Reduced MCU memory requirement
 MCU awake to poll radio – more current
 MCU asleep while radio qualifies data
 ADC required for temp / battery sensor
 Integrated ADC, temp sensor, battery detect
 Additional SW developer burden
 Packet qualification simplifies SW
Reduced performance and battery life,
increased cost, complicated design

How to win the MCU/RF bundle
 RF performance/features critical for product selection
 Link range
 Battery life
 Winning the radio socket creates opportunity to win MCU
 Some customers need unique MCU features
 0.9V battery operation
 Capacitive touch-sense
 For other “generic” MCU applications – make it easy!
 Reference designs with radio and MCU
EZLink modules are ideal reference platform
 Example radio application code
 Networking software – EZMac
 Domain specific software
AES-128 encryption
Frequency hoping
30
Supporting Reference Source Code
 MCU and RF teams porting RF code to C8051 MCU
 Point-to-point simple links
 Transceiver “ping-pong”
 EZMac
 EZMac Lite—smallest footprint
 EZMac Standard—adds multicast and error detection
support
 EZMac Plus—adds packet forwards
 EZMacPRO—lower footprint, uses hardware blocks in EZRadioPRO
devices
(currently in development)
 Frequency hopping spread spectrum
 All of the above is available in the development kits
