Low-power MCU family expanded, gets enhanced ecosystem

STMicroelectronics has introduced a development ecosystem for its latest low-power, high-performance STM32L4 microcontrollers (MCU) and expanded the series with five product lines comprising a range of package and memory-density options.

The expanded STM32L4 ecosystem builds on ST’s free 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 – the first Nucleo-32 board to integrate an MCU in the tiny QFN32 package – 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 added STM32L43x and STM32L44x MCU product lines comprise variants with versatile combinations of an integrated USB controller, an LCD controller, and cryptography. Up to 256 kByte of Flash and low-pin-count-package choices suit them for cost-sensitive applications. The added devices also rich digital peripherals including a True Random-Number Generator (TRNG) and smart analogue features such as a 12-bit, 5 Msample/sec ADC, internal voltage reference, and ultra-low-power comparators.
