♠ Ultra-low-power Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, ruo 128KB Flash, 40KB SRAM, analog, ext.SMPS
Ngwa STM32L412xx bụ microcontrollers nwere obere ike dabere na Arm® Cortex®-M4 32-bit RISC core na-arụ ọrụ n'ogo ruru 80 MHz.Cortex-M4 isi nwere atụmatụ otu nkenke nke na-akwado Arm® otu-nkenke data-nhazi data na ụdị data.Ọ na-arụkwa ọrụ ntuziaka DSP zuru oke yana ngalaba nchekwa nchekwa (MPU) nke na-eme ka nchekwa ngwa dịkwuo elu.
Ngwa STM32L412xx tinyere ncheta ọsọ ọsọ (Flash ebe nchekwa ruo 128 Kbyte, 40 Kbyte nke SRAM), Quad SPI Flash memories interface (dị na ngwugwu niile) yana ọtụtụ ụdị nkwalite I/Os na mpụta ejikọrọ na ụgbọ ala APB abụọ. , ụgbọ ala AHB abụọ na nnukwu ụgbọ ala 32-bit multi-AHB.
Ngwa STM32L412xx tinyere ọtụtụ usoro nchebe maka ebe nchekwa Flash agbakwunyere na SRAM: nchedo ịgụ ihe, ide ihe nchedo, nchedo koodu ịgụ ihe na Firewall.
Ngwa ndị a na-enye 12-bit ADC ngwa ngwa (5 Msps), ndị comparators abụọ, otu amplifier arụ ọrụ, RTC dị ala, otu ngụ oge 32-bit n'ozuzu, otu 16-bit PWM ngụ oge raara nye njikwa moto, izugbe anọ - nzube 16-bit ngụ oge, na abụọ 16-bit obere ike ngụ oge.
Na mgbakwunye, ihe ruru ọwa mmetụta capacitive 12 dị.
Ha na-egosipụta ọkọlọtọ na interface nkwukọrịta dị elu, ya bụ I2C atọ, SPI abụọ, USARTs atọ na otu UART dị ala, otu ngwaọrụ kristal zuru oke USB dị obere.
STM32L412xx na-arụ ọrụ na -40 ka +85 °C (+105 °C junction) na -40 ruo +125 °C (+130 °C junction) okpomọkụ sitere na 1.71 ruo 3.6 VDD ike ọkọnọ mgbe ị na-eji ime LDO regulator. yana ọkụ 1.00 ruo 1.32V VDD12 mgbe ị na-eji ọkọnọ SMPS mpụga.Ụdị ụdị nchekwa ike zuru oke na-eme ka o kwe omume ịmepụta ngwa ndị dị ala.
A na-akwado ụfọdụ akụrụngwa ike nọọrọ onwe ya: ntinye aka na-enye onwe ya maka ADC, OPAMP na comparator.Ntinye VBAT na-eme ka o kwe omume ịkwado RTC na ndekọ ndabere.Enwere ike iji ihe enyemaka VDD12 raara onwe ya nye iji gafere onye na-achịkwa LDO dị n'ime mgbe ejikọtara na SMPS dị na mpụga.
Ezinụlọ STM32L412xx na-enye ngwugwu isii sitere na ngwugwu 32 ruo 64-pin.
