Every wireless device is getting smarter so why not combine the radio-frequency (RF) circuitry with the processor. "Can do" said Silicon Labs this week at Embedded World in Nuremberg, Germany. Look for wireless electronic devices to get smaller and lower power as a result of wireless microcontrollers. R.C.J.
Silicon Laboratories Inc. mated its family of wireless transceivers to its line of ultra-low-power microcontrollers to create a family of a dozen wireless microcontrollers. Silicon Labs claims its ultra-low-power family of 8051-compatible microcontrollers already had the industry's lowest active current consumption, and its lowest sleep current. Plus its line of wireless transceivers already offered +20 dBm output power without an external PA and -121 dBm receiver sensitivity. Together with an on-chip dc-to-dc converter for operating at .9 volts, the new Si10xx family of wireless microcontrollers is claimed to increase the lifetime of the battery powered RF devices using it by five times.
