STM32L431CBT6 IC MCU 32BIT 128KB FLASH 48LQFP

Fa'amatalaga

O masini STM32L431xx o microcontrollers ultra-maualalo 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 STM32L431xx e fa'apipi'i ai manatuaga maualuga (Flash memory e o'o atu i le 256 Kbyte, 64 Kbyte o le SRAM), o le Quad SPI flash memory interface (maua i luga o afifi uma) ma le tele o fa'aleleia I/Os ma peripherals e feso'ota'i i pasi APB e lua. , lua pasi AHB ma le 32-bit multi-AHB pasi matrix.O masini STM32L431xx 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 le vave 12-bit ADC (5 Msps), lua faʻatusatusaga, tasi faʻamalosi faʻamalositino, lua DAC alalaupapa, faʻamaufaʻailoga eletise i totonu, se RTC maualalo, tasi taimi masani 32-bit, tasi 16-bit PWM timer. fa'apitoa mo le fa'atonutonuina o afi, fa'auma fa'amoemoe lautele 16-bit timers, ma lua 16-bit low-power timers.E le gata i lea, e oʻo atu i le 21 capacitive sensing channel o loʻo avanoa.Latou te faʻaalia foʻi fesoʻotaʻiga masani ma fesoʻotaʻiga maualuga.• Tolu I2Cs • Tolu SPIs • Tolu USARTs ma le tasi Low-Power UART.• Tasi SAI (Serial Audio Interfaces) • Tasi SDMMC • Tasi CAN • Tasi SWPMI (Single Wire Protocol Master Interface) O le STM32L431xx e galue i le -40 i le +85 °C (+105 °C junction), -40 i le +105 ° C (+125 °C junction) ma le -40 i le +125 °C (+130 °C junction) o le vevela e amata mai i le 1.71 i le 3.6 V le eletise.O se seti atoatoa o auala fa'asao eletise e fa'atagaina ai le mamanu o talosaga maualalo.O nisi o sapalai eletise tuto'atasi e lagolagoina: fa'aoga tuto'atasi tuto'atasi mo ADC, DAC, OPAMP ma fa'atusa.O le VBAT fa'aoga e mafai ai ona fa'asaoina le RTC ma fa'amaumauga fa'amaumauga.O le aiga STM32L431xx e ofoina atu pusa e iva mai le 32 i le 100-pin afifi.
