STM32L4 Series Ultra-low-power and performance STM32™ ultra-low-power at 100 DMIPS with DSP and FPU ULTRA-LOW-POWER EXCELLENCE The STM32L4 microcontroller is based on a new ultra-low-power platform featuring FlexPowerControl which extends flexibility to reach optimized power consumptions: With an EEMBC ULPBench score of 176.7 ULPBench™-CP, the STM32L4 outperforms the market in the ultra-low-power domain. OUTSTANDING LOW-POWER MODES Wake-up time VBAT 2 nA / 200 nA* 250 µs SHUTDOWN 14 µs STANDBY 14 µs STANDBY+ 32 Kbytes RAM 5 µs STOP 2 full retention 8 nA / 200 nA* 28 nA / 280 nA* 170 nA / 450 nA* WITH PERFORMANCE Offering up to 1 Mbyte of Flash (dual bank) memory and 128 Kbytes of SRAM, the STM32L4 unleashes the ARM® Cortex®-M4 power efficiency with floating point unit (FPU) and DSP instructions. It delivers 100 DMIPS / 273 CoreMark thanks to the ST ART Accelerator™ at 80 MHz. The entire system performance is optimized using a multi-AHB bus matrix and DMA controllers. 6 cycles SLEEP RUN 1.0 µA / 1.28 µA* 28 µA / MHz 84 µA / MHz * without RTC / with RTC www.st.com/stm32l4 STM32L486 BLOCK DIAGRAM HARDWARE TOOLS Parallel Interface FSMC 8-/16-bit (TFT-LCD, SRAM, NOR, NAND) Display Connectivity ARM Cortex®-M4 CPU 80 MHz FPU MPU ETM USB OTG 1x SD/SDIO/MMC, 3x SPI, 3x I²C, 1x CAN, 1x Quad SPI, 5x USART + 1 x ULP UART, 1 x SWP DMA Digital ® STM32 Cube LCD driver 8 x 40 Timers 17 timers including: 2 x 16-bit advanced motor control timers 2 x ULP timers 7 x 16-bit-timers 2 x 32-bit timers ART Accelerator TM Up to 1-Mbyte Flash with ECC Dual Bank I/Os Up to 114 I/Os Touch-sensing controller 128 Kbytes RAM AES (256-bit), TRNG, 2 x SAI, DFSDM (8 channels) Analog 3x 16-bit ADC, 2 x DAC, 2 x comparators, 2 x Op amps 1 x Temperature sensor A full set of evaluation boards enables flexible prototyping as well as full STM32L4 evaluation.
