All processor manufacturers want low-power consumption or high performenace. Now, ST Microelectronics shows a new type of processor – STM32L476 which combines high performance and low-power consumption.
This type of processor contains various peripherals.
The website chiptron.cz, the first of all, owns this processor with development board Nucleo.
What do you can find on this development board? Nucleo is family of development boards. It means that Nucleo is the same as different Nucleos with different processors.
– programmer/debugger ST/LINKv2
– Arduino? like connectors and ST Morpho connectors
– 2 buttons (USER and RESET)
– 2 LED diods
And why this processor is better than others?:
– ARM? CORTEX?-M4 80MHz
– 1 MB FLASH, 128KB SRAM
– 3x 12-bit ADC (5 MSPS)
– two comparators
– two operational amplifiers
– two DAC channels
– an internal voltage reference buffer
– low-power RTC
– two general-purpose 32-bit timer
– two 16-bit PWM timers dedicated to motor control
– seven general-purpose 16-bit timers
– and two 16-bit low-power timers
– the STM32L476 supports four digital filters for external sigma delta modulators (DFSDM)
– 24 capacitive sensing channels
– LCD driver 8×40 or 4×44, with internal step-up converter
and next advantages?
– 1.71 V to 3.6 V power supply
– 300 nA in VBAT mode: supply for RTC and 32×32-bit backup registers
– 30 nA Shutdown mode (5 wakeup pins)
– 130 nA Standby mode (5 wakeup pins)
– 1.1 ?A Stop 2 mode, 1.4 ?A Stop 2 with RTC
– 100 ?A/MHz run mode
– 100DMIPS/1.25DMIPS/MHz
– 14-channel DMA controller
– 2x SAIs (serial audio interface)
– 3x I2C FM+(1 Mbit/s), SMBus/PMBus
– 6x USARTs (ISO 7816, LIN, IrDA, modem)
– 3x SPIs (4x SPIs s Quad SPI)
– CAN (2.0B Active) a SDMMC interface
– true random number generator
