♠ Ultra-low-power Arm® Cortex®-M4 32-bit MCU + FPU, 100 DMIPS, ruo 1 MB Flash, 320 KB SRAM, USB OTG FS, ọdịyo, mpụga SMPS
Ngwa STM32L496xx 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 STM32L496xx na-etinye ihe ncheta dị elu (ihe ruru 1 Mbyte nke ebe nchekwa Flash, 320 Kbyte nke SRAM), onye na-ahụ maka ebe nchekwa mpụga na-agbanwe agbanwe (FSMC) maka ebe nchekwa dị iche iche (maka ngwaọrụ nwere ngwugwu 100 pin na ndị ọzọ), Quad SPI Flash memories interface (dị na ngwugwu niile jikọtara ya na nke ukwuu) Ụgbọ ala APB, ụgbọ ala AHB abụọ na nnukwu ụgbọ ala 32-bit multi-AHB.
Ngwa STM32L496xx 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, obere ikike RTC, ihe ngụ oge 32-bit abụọ, ngụ oge 16-bit PWM raara onwe ya nye njikwa moto, ebumnuche izugbe 16-bit 16 na oge abụọ. Ngwa ndị a na-akwado ihe nzacha dijitalụ anọ maka mpụga sigma delta modulators (DFSDM).
Na mgbakwunye, ihe ruru ọwa mmetụta capacitive 24 dị. Ngwa ndị ahụ gbakwunyere 8x40 ọkwọ ụgbọ ala LCD agbakwunyere ma ọ bụ 4 × 44, yana ihe ntụgharị nrịgo dị n'ime.
Ha na-egosipụta ọkọlọtọ na interface nkwukọrịta dị elu, ya bụ I2C anọ, SPI atọ, USARTs atọ, UARTs abụọ na otu UART dị ala, SAI abụọ, otu SDMMC, CAN abụọ, otu USB OTG zuru oke, otu SWPMI (otu waya protocol master interface), interface igwefoto na onye njikwa DMA2D.
STM32L496xx na-arụ ọrụ na -40 ka +85 °C (+105 °C junction), -40 ka +125 °C (+130 °C junction) okpomọkụ sitere na 1.71 ruo 3.6 V VDD ike ọkọnọ mgbe eji esịtidem LDO regulator na a 1.05 ka VDD mpụga ọkọnọ 1.32SM. Ụdị ụdị nchekwa ike zuru oke na-eme ka o kwe omume ịmepụta ngwa ngwa dị ala.
A na-akwado ụfọdụ ihe enyemaka nọọrọ onwe ya: ntinye aka ntinye aka analog maka ADC, DAC, OPAMPs na comparators, 3.3 V ntinye ọkọnọ raara onwe ya nye maka USB na ruo 14 I/O nwere ike ịnye onwe ya ruo 1.08 V. 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 STM32L496xx na-enye ngwugwu asaa site na ngwungwu 64-pin ruo 169-pin.
