♠ Ultra-maualalo-mana Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, e oo atu i le 128KB Flash, 40KB SRAM, analog, ext.SMPS

O masini STM32L412xx 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 STM32L412xx e fa'apipi'i ai manatuaga maualuga (Flash memory up to 128 Kbyte, 40 Kbyte of SRAM), se Quad SPI Flash memory interface (maua i luga o afifi uma) ma le tele o fa'alelei 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 STM32L412xx 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 vave 12-bit ADC (5 Msps), lua faʻatusatusa, tasi faʻamalosi faʻamalositino, se RTC maualalo-malosi, tasi faʻamoemoe lautele 32-bit timer, tasi 16-bit PWM timer faʻapitoa mo le faʻatonutonuina o afi, fa lautele- fa'amoemoega 16-bit timers, ma lua 16-bit low-power timers.

E le gata i lea, e oʻo atu i le 12 capacitive sensing channel o loʻo avanoa.

Latou te faʻaalia foʻi fesoʻotaʻiga masani ma fesoʻotaʻiga, e taʻua tolu I2Cs, lua SPI, tolu USARTs ma le tasi Low-Power UART, tasi le USB faʻavavevave masini tioata itiiti.

O le STM32L412xx o loʻo galue i le -40 i le +85 °C (+105 °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 VDD sapalai eletise pe a faʻaogaina le LDO regulator i totonu. ma le 1.00 i le 1.32V VDD12 sapalai eletise pe a faʻaogaina fafo SMPS sapalai.O se seti atoatoa o auala fa'asao eletise e mafai ai le mamanu o talosaga maualalo-malosi.

O lo'o lagolagoina nisi o sapalai eletise tuto'atasi: fa'aoga tuto'atasi tuto'atasi mo ADC, OPAMP ma fa'atusa.O le VBAT fa'aoga e mafai ai ona fa'asaoina le RTC ma fa'amaumauga fa'amaumauga.E mafai ona fa'aogaina sapalai eletise VDD12 tu'ufa'atasi e pasi ai le fa'atonu LDO i totonu pe a feso'ota'i atu i se SMPS fafo.

O le aiga STM32L412xx e ofoina atu afifi e ono mai le 32 i le 64-pin afifi.
