STMicroelectronics rolls out a new development ecosystem for its latest low-power, high-performance STM32L4 microcontrollers (MCU) and also for its new five new product line comprising a range of package and memory-density options.
The new ecosystem is sought to be built on ST’s free and easy-to-use STM32Cube platform which integrates:
- The STM32CubeMX initialization-code generator and configurator with easy-to-use power estimation for ultra-low-power design.
- 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 – touted as 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 new STM32L43x and STM32L44x MCU product lines is said to comprise variants with versatile combinations of an integrated USB controller, an LCD controller, and cryptography for security-conscious applications.
Demonstrating low-power technology with FlexPowerControl (FPC) the new devices feature separate supply-voltage domains for gating power individually to analog peripherals, USB circuits, and I/Os.
Batch-Acquisition Mode (BAM) enables energy-efficient data capture and seven reduced-power modes with further sub-modes maximize energy savings in a wide range of operating conditions.
ST’s low-power technologies, combined with the performance of the 32-bit ARM Cortex-M4F core, ensure high efficiency according to EEMBC ULPBench tests.
The STM32L433 is certified at 177ULPMark-CP at 3.0V, tested without the aid of a step-down converter. Aided by ST’s innovative ART Accelerator, outright performance is also high at 273 CoreMark.
Availability, Packaging and Pricing
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. Prices start from $2.045 for the STM32L431KBU6 with 128KByte Flash and 64KByte SRAM in QFN-32, for orders of 10,000 pieces.
