♠ 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.
The STM32L412xx ngwaọrụ embed elu-ọsọ na-echeta (Flash ebe nchekwa ruo 128 Kbyte, 40 Kbyte nke SRAM), a Quad SPI Flash memories interface (dị na niile ngwugwu) na ọtụtụ nso nke enwekwukwa I / Os na peripherals ejikọrọ na abụọ APB ụgbọ ala, abụọ AHB2 ụgbọ ala AHB- na multi-bit buses.
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 obere, otu ngụ oge 32-bit n'ozuzu, otu 16-bit PWM ngụ oge raara onwe ya nye na njikwa moto, ihe ngụ oge 16-bit n'ozuzu, yana ngụ oge 16-bit dị ala.
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 ka +125 °C (+ 130 °C junction) okpomọkụ sitere na 1.71 ruo 3.6 VDD ike ọkọnọ mgbe eji esịtidem LDO regulator na a 1.00 ka VDD mpụga ọkọnọ 1.2SM. 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.
