ST’s Cortex-M4F MCUs get bigger ecosystem


STMicroelectronics has introduced a development system for its STM32L4 MCUs.

STThe embedded ecosystem comprises the STM32CubeMXinitialisation-code generator and configurator with a power estimation capability.

The STM32CubeL4 package also contains middleware components, Nucleo-32 Board-Support Package (BSP), Hardware Abstraction Layer (HAL), and Low-Layer APIs (LLAPIs).

The NUCLEO-L432KC board integrates an MCU in a QFN32 package and 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.

There are also five new STM32L43x and STM32L44x ARM Cortex-M4F MCU product lines including options of having an integrated USB controller, an LCD controller, and cryptography for security-conscious applications. There is also up to 256kbyte of flash.

Peripherals include: a True Random-Number Generator (TRNG), a 12-bit 5Msample/s ADC, internal voltage reference, and comparators.

The new devices are available in small-form-factor packages from 5mm x 5mm QFN-32 to 14mm x 14mm LQFP-100, including 3.14mm x 3.13mm WLCSP.
