By adding the new STM32G0 microcontrollers (MCUs) to the STM32 family, STMicroelectronics is stretching its portfolio of Arm Cortex-M-core MCUs to more thoroughly cover key embedded-market segments. The new G0 series targets entry-level applications that require greater energy efficiency, functionality, security and value, in a smaller footprint.
Flexible packaging and memory options enable designers to do more within less space, and save cost. A new power distribution architecture reduces external power and ground connections to just a single pair of pins, allowing more of the package pins - a precious resource in many embedded projects - to be allocated for user connectivity.
In addition, ST is making large memory densities available in small and economical low-pin-count packages. On top of this, the new generation features power-saving innovations that trim consumption close to that of specialised ultra-low-power devices.
To provide robust security for today’s connected devices, the STM32G0 series introduces a variety of hardware-based features including memory protection to support secure boot. Some devices in the series add to these features an AES-256 hardware cryptographic accelerator with a true random number generator (TRNG) to aid encryption.
Another valuable feature that anticipates a growing need is support for the latest USB Type-C specifications that allow easy, high-speed connectivity and battery charging, including Power Delivery version 3.0.
