Product details
STM32L4 Series Microcontrollers, STMicroelectronics
The STM32L476/STM32L486 devices extend the ultra-low-power portfolio and performance with an ARM® Cortex®-M4 core with DSP and Floating-Point Unit (FPU) at 80MHz. This series offers USB OTG 2.0 full speed, a Liquid Crystal Display (LCD) driver in addition to the significant set of peripherals.
Advanced Encryption Standard (AES) 128-/256-bit hardware encryption is available on STM32L486 devices.
Ultra-low-power with FlexPowerControl
ARM® 32-bit Cortex®-M4 Core CPU with FPU, Adaptive real-time accelerator (ART Accelerator™)
Different clock sources with prescaler, safe clock switching and clock management
Real Time Clock (RTC) with Hardware calendar, alarms and calibration
LCD controller 8´40 or 4´44 with step-up converter
Up to 24 capacitive sensing channels
16 timers
Up to 114 fast Inputs/Outputs, most 5V-tolerant
Up to 1MB Flash memory
Four digital filters for sigma delta modulator
Rich analogue peripherals, ADC, DAC, Op Amp, Comparators
Communication interfaces, USB OTG 2.0, SAI, I²C, USART, SPI, CAN, SWPMI
14-channel DMA controller
True random number generator
CRC calculation unit, 96-bit unique ID
Serial Wire Debug (SWD), JTAG, Embedded Trace Macrocell™ development support
STM32L4 Series 32-Bit ARM® Cortex®-M4 Microcontrollers, STMicroelectronics
The STM32L4 series of ultra-low-power microcontrollers deliver 100DMIPS based on its ARM® Cortex®-M4 core with Floating Point Unit (FPU) and ST ART Accelerator™ at 80MHz.
STM32L4 microcontrollers offer dynamic voltage scaling to balance power consumption with processing demand, low-power peripherals available in Stop mode, safety and security features.
