Daim npav IC daim npav them ua ntej hluav taws xob muaj xws li ntau yam qauv thiab cov khoom siv, suav nrog chav ntsuas hluav taws xob, IC daim npav interface, chav ua cov ntaub ntawv, thiab chav sib txuas lus sib txuas. Lub zog ntsuas hluav taws xob feem ntau muaj lub zog ntsuas nti, tam sim no transformers, voltage transformers, thiab filtering circuits. IC daim npav interface feem ntau suav nrog IC daim npav qhov, daim npav IC nyeem -sau Circuit Court, thiab chav ua cov ntaub ntawv.
Cov ntaub ntawv ua haujlwm feem ntau muaj microprocessor, nco, thiab cov zaub. Ua raws li "lub hlwb" ntawm lub ntsuas ntsuas ntse, microprocessor yog lub luag haujlwm rau kev ua cov ntaub ntawv piv txwv, tswj cov zaub, thiab txhawb kev sib pauv ntawm cov ntaub ntawv sab nraud. Mainstream MCU cov kev daws teeb meem suav nrog Freescale's S08MZ, S08GW, MCF51EM, thiab Kinetis K30 series; STMicroelectronics 'low- zog STM8L thiab STM32 series; thiab Texas Instruments 'MSP430 series. Cov ntsuas ntse feem ntau ua ke nrog ESAM kev ruaj ntseg module los xyuas kom meej cov ntaub ntawv kev ruaj ntseg.
Cov chav sib txuas lus interface feem ntau muaj kev sib txuas lus module thiab txuas txuas txuas txuas txuas. Cov kev daws teeb meem kev sib txuas lus suav nrog txoj kev siv xov tooj-xws li RS-485 lossis Power Line Communication (PLC)- nrog rau txoj hauv kev wireless, xws li 4G cellular kev sib txuas lus thiab NB-IoT (Narrowband Internet of Things). Rau cov cab kuj hloov kho cov qauv xws li OFDM thiab S-FSK, ntau lub tuam txhab muab cov chips tshwj xeeb xws li Freescale's MC13260 thiab STMicroelectronics' ST7590. Cov kev daws teeb meem wireless feem ntau yog raws li ZigBee thev naus laus zis, ua piv txwv los ntawm Freescale's MC13202 thiab MC1322x series.
