MCU_STM32L4 Target Family Info

Back to Target Families Index ^

Features Supported

Peripheral Drivers Supported

• CAN: Controller Area Network (CAN) peripheral driver
• I2C Controller/Master: I2C driver for synchronous (blocking) controller/master mode
• I2C Peripheral/Slave: I2C for interrupt-based peripheral/slave mode
• Sleep: Support for sending the processor to sleep when no threads/ISRs are executing.
• Flash IAP: Driver allowing In-Application Programming (IAP) of the MCU flash memory.
• Analog Outputs: Analog output (DAC) peripheral driver
• Async I2C Controller/Master: Driver allowing I2C controller mode to be used in the background via interrupts and/or DMA.
• RTC: Real-Time Clock. Clock which keeps track of real world time, usually using a low frequency, accurate clock.
• SPI Peripheral/Slave: Serial Peripheral Interface (SPI) device/slave mode
• Serial (UART): Support for buffered and unbuffered serial (UART) ports
• SPI Controller/Master: Serial Peripheral Interface (SPI) controller/master mode
• Watchdog: Peripheral which resets the chip if software doesn't service it within a configurable amount of time. Used to guard against software hangs.
• Legacy Async Serial (UART): Legacy asynchronous serial API via SerialBase
• μs Ticker: Clock peripheral with at least microsecond resolution that Mbed uses to implement Timer and Ticker.
• Serial RTS/CTS Flow Control: Serial (UART) peripheral supports using RTS and/or CTS pins for hardware flow control.
• Memory Protection Unit: Mbed supports configuring the MPU on this device to disable writing to ROM and executing from RAM.
• Hardware CRC: Driver for CRC Accelerator peripheral, used to accelerate certain CRC computations.
• GPIO Interrupts: GPIO input pin interrupt support
• GPIO Port I/O: Driver for using an entire GPIO port as a bidirectional I/O port.
• True Random Number Generator: Cryptographic-grade True Random Number Generator (TRNG). This is required to implement SSL communications securely unless you provision devices with an entropy seed stored in nonvolatile storage.
• Analog Inputs: Analog input (ADC) peripheral driver
• PWM Out: Pulse Width Modulation (PWM) generator peripheral driver
• GPIO Port Output: Driver for writing to an entire GPIO port at a time
• Reset Reason: Support for determining the cause of the most recent MCU reset.
• Async SPI: Allows use of SPI controller mode in the background via interrupts and/or DMA.
• GPIO Port Input: Driver for reading from an entire GPIO port at a time
