♠ Ultra-low-power Arm® Cortex®-M4 32-bit MCU+FPU, 100DMIPS, ruo 1MB Flash, 128 KB SRAM, USB OTG FS, LCD, ext.SMPS
Ngwa STM32L476xx bụ ndị na-ahụ maka microcontrollers nwere obere ike dabere na arụmarụ Arm® Cortex®-M4 32-bit RISC core na-arụ ọrụ na ugboro ruru 80 MHz.Isi Cortex-M4 na-egosi otu nkenke 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 STM32L476xx na-etinye ihe ncheta dị elu (Flash memory ruo 1 Mbyte, ruo 128 Kbyte nke SRAM), onye na-ahụ maka ebe nchekwa mpụga na-agbanwe agbanwe (FSMC) maka ncheta static (maka ngwaọrụ nwere ngwugwu 100 pin na ndị ọzọ), Quad SPI flash memories interface (dị na ngwugwu niile) yana ọtụtụ ụdị nkwalite I/Os na mpụta ejikọrọ na bọs APB abụọ, ụgbọ ala AHB abụọ na nnukwu ụgbọ ala 32-bit multi-AHB.
Ngwa STM32L476xx 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 ihe ruru 12-bit ADC ngwa ngwa ngwa ngwa atọ (5 Msps), ndị comparators abụọ, amplifiers arụ ọrụ abụọ, ọwa DAC abụọ, ihe nchekwa voltaji dị n'ime, RTC dị ala, ihe ngụ oge 32-bit abụọ, abụọ 16. -bit PWM ngụ oge raara onwe ya nye na njikwa moto, ihe ngụ oge 16-bit izugbe asaa, yana ngụ oge dị obere 16-bit.Ngwa ndị a na-akwado ihe nzacha dijitalụ anọ maka mpụga sigma delta modulators (DFSDM).
