Wireless remote control technologies are everywhere--from garage door openers to building automation--but building them has until now required dozens of components. Look for ultra-small remotes enabled by single-chip radios over the next few years. R.C.J.
Silicon Labs EZradio SoC requires only one external component (capacitor at right) whereas traditional SAW designs require as many as 41 external components.
A new wireless remote-control system-on-a-chip enables remote-keyless entry designs to slim down their bill-of-materials to one external component, compared to dozens required for traditional solutions, according to Silicon Laboratories Inc., which announced the EZRadio single-chip radio frequency (RF) transmitter...Silicon Labs combined its RF microcontroller and its all-CMOS oscillator technologies to enable the EZRadio Si4010 SoC radio frequency (RF) transmitter to eliminate the need for external components (except for a single capacitor). The EZRadio chip is designed for remote-keyless entry applications such as garage door openers, building automation remotes, secure-entry devices and other remote controls that require only a one-way RF link...
