♠ 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.
Ngwa STM32L451xx tinyere ihe ncheta dị elu (Flash ebe nchekwa ruo 512 Kbyte, 160 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 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, ihe nchekwa voltaji dị n'ime, RTC dị ala, otu ngụ oge 32-bit n'ozuzu, otu 16-bit. Ngụ oge PWM raara onwe ya nye na njikwa moto, ihe ngụ oge 16-bit izugbe anọ, yana ngụ oge dị obere 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.
