Device!Description!!
The*iND83231*high*voltage*wireless*microcontroller*consists*of*a*highly*
integrate d *3 2-bit*general*purpose*ARM*M0*based*microcontroller*and*433*
MHz*ISM*Band*Transceiver*and*operates*from*a*12V*DC*supply.***
The*integrated*wireless*transceiver*operates*in*the*433*MHz*ISM*band*
with*capability*from*310MHz*–*450*MHz.*It*has*a*maximum*transmit*power*
of*+13dBm*and*a*receive*sensitivity*in*excess*of*-110dBm.*The*power*
consumption*of*the*transceiver*leads*the*industry*with*4mA*of*current*
consumption*in*receive*mode*and*18m A*at*maxim um *output*power. *
The*iND83231*also*integrates*160kB*of*flash*RAM*and*8kB*of*SRAM*on*die*
for*feature-ric h*ap plica tion s*or*applications*requiring*redund ancy*of*data*
storage.**It*integrates*multiple*clocking*options*including*a*high*accuracy*
