Fa'amatalaga
O masini STM32L471xx o microcontrollers e sili ona maualalo le malosi e faʻavae i luga o le maualuga o le Arm® Cortex®-M4 32-bit RISC autu o loʻo faʻaogaina i se taimi e oʻo atu i le 80 MHz.O le Cortex-M4 autu o loʻo faʻaalia ai le Floating point unit (FPU) e tasi le saʻo e lagolagoina uma Arm® faʻatonuga faʻasologa o faʻamatalaga ma ituaiga faʻamaumauga.O lo'o fa'atinoina fo'i se seti atoa o fa'atonuga a le DSP ma se vaega o le puipuiga o le manatua (MPU) lea e fa'aleleia ai le saogalemu o talosaga.O masini STM32L471xx o loʻo faʻapipiʻiina ai manatuaga maualuga (Flash memory e oʻo atu i le 1 Mbyte, e oʻo atu i le 128 Kbyte o le SRAM), o se mea e faʻaogaina ai le mafaufau i fafo (FSMC) mo manatuaga tumau (mo masini e iai pusa o 100 pine ma sili atu), a Quad SPI flash memory interface (avanoa i luga o afifi uma) ma le tele o faʻaleleia I / Os ma peripherals e fesoʻotaʻi atu i pasi APB e lua, pasi AHB e lua ma le 32-bit multi-AHB bus matrix.O masini STM32L471xx o lo'o fa'apipi'iina ai le tele o puipuiga mo le fa'apipi'iina o le Flash memory ma le SRAM: puipuiga o le faitau tusi, puipuiga o le tusitusi, puipuiga o le faitau tusi ma le Pa puipui.O masini e ofoina atu i le tolu vave 12-bit ADCs (5 Msps), lua faʻatusatusaga, lua faʻamalosi faʻamalositino, lua DAC channels, se faʻamaufaʻailoga eletise i totonu, se RTC maualalo, lua faʻamoemoe lautele 32-bit timer, lua 16 -bit PWM timers fa'apitoa mo le fa'atonuina o afi, fitu fa'amoemoe lautele 16-bit timers, ma lua 16-bit fa'amaulalo-mana timers.O masini e lagolagoina fa'aputuga numera fa mo fafo sigma delta modulators (DFSDM).
