Development ecosystem launched and microcontroller series expanded
STMicroelectronics has introduced the development ecosystem for its latest low-power, high-performance STM32L4 microcontrollers (MCU) and has expanded the series with five new product lines comprising a range of package and memory-density options.
The expanded STM32L4 ecosystem builds on the company’s STM32Cube platform. This comprises the STM32CubeMX initialization-code generator and configurator with power estimation for ultra-low-power design, and the STM32CubeL4 package that contains middleware components, Nucleo-32 Board-Support Package (BSP), Hardware Abstraction Layer (HAL), and Low-Layer APIs (LLAPIs).
For a quick start to new projects, the slim-form-factor NUCLEO-L432KC board includes an STM32L432KCU6 device (UFQFPN32) and provides direct access to ARM mbed online tools. Its Arduino Nano pin layout simplifies function extensions, and the integrated ST-Link debugger/programmer supports mass storage and allows probe-free debugging.
Five new STM32L43x and STM32L44x MCU product lines comprise variants with versatile combinations of an integrated USB controller, an LCD controller, and cryptography for security-conscious applications.
The devices offer up to 256KByte of Flash and rich digital peripherals including a True Random-Number Generator (TRNG). There are also smart analogue features such as a 12-bit 5Msample/s ADC, internal voltage reference, and ultra-low-power comparators.
All devices include FlexPowerControl (FPC) with features such as separate supply-voltage domains for gating power individually to analogue peripherals, USB circuits, and I/Os. Batch-Acquisition Mode (BAM) enables energy-efficient data capture and seven reduced-power modes with further sub-modes help maximise energy savings in a wide range of operating conditions.
The new devices are available immediately, in small-form-factor packages from 5mm x 5mm QFN-32 to 14mm x 14mm LQFP-100, including 3.14mm x 3.13mm WLCSP.
