♠ Ultra-low-power Arm® Cortex®-M4 32-bit MCU + FPU, 100DMIPS, ruo 512KB Flash, 160KB SRAM, analọg, ọdịyo
Ngwa STM32L451xx 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 STM32L451xx ngwaọrụ embed elu-ọsọ na-echeta (Flash ebe nchekwa ruo 512 Kbyte, 160 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, a multi-AH32 buses na ụgbọ ala AH3-bit abụọ.
Ngwa STM32L451xx 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 ngwa ngwa 12-bit ADC (5 Msps), ndị comparators abụọ, otu amplifier na-arụ ọrụ, otu ọwa DAC, ebe nchekwa voltaji dị n'ime, obere ike RTC, otu ngụ oge 32-bit n'ozuzu, otu 16-bit PWM ngụ oge raara onwe ya nye njikwa moto, ebumnuche izugbe 16-bit ngụ oge, na obere oge 16-bit.
Na mgbakwunye, ihe ruru ọwa mmetụta capacitive 21 dị.
Ha na-egosipụta ọkọlọtọ na interface nkwukọrịta dị elu, ya bụ I2C anọ, SPI atọ, USART atọ, otu UART na otu Low-Power UART, otu SAI, otu SDMMC, otu CAN.
STM32L451xx na-arụ ọrụ na -40 ruo +85 °C (+105 Celsius C junction) na -40 ruo +125 °C (+130 °C junction) okpomọkụ sitere na 1.71 ruo 3.6 V ike ọkọnọ. 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, DAC, OPAMP na comparators. Ntinye VBAT na-eme ka o kwe omume ịkwado RTC na ndekọ ndabere.
Ezinụlọ STM32L451xx na-enye ngwugwu isii sitere na ngwugwu 48 ruo 100-pin.
