ST Releases Compact 32-pin STM8 Nucleo Boards


Boards are based on the 128Kb STM8S207K8 MCU with integrated debugger and programmer


STMicroelectronics is making design starts using 8-bit STM8 microcontrollers (MCUs) faster, more affordable, and more accessible for creative minds of all types by introducing new development boards in the easy-to-use Nucleo-32 form factor.

An ST-LINK debugger/programmer is integrated, which saves using an external debug probe and allows simple drag-and-drop Flash programming. Arduino™ Nano pins simplify functional expansion using off-the-shelf shields and let users connect with open-source hardware communities. The boards are supported by major development toolchains including IAR Embedded Workbench for STM8 and Cosmic CXSTM8.

STM8 MCUs feature a high-performing 8-bit core, generous on-chip memory including up to 128Kbyte of Flash, and state-of-the-art peripherals shared with the STM32 MCU family such as timers, analog peripherals, CAN2.0B, and digital interfaces. The STM8 MCUs are a popular choice for creating smart sensors, actuators, and other products within tight power, space, and cost constraints.

The first available STM8 Nucleo-32 board, the NUCLEO-8S207K8, contains a 32-pin STM8S207K8 MCU, which provides features including 12 high-current outputs and multiple capture-compare channels.
