STMicroelectronics has expanded the STM32G0 Arm Cortex-M0+ microcontroller (MCU) series with more product variants and features such as dual-bank Flash, support for CAN FD and crystal-less USB Full-Speed data/host support.

For budget-conscious applications, the STM32G050 Value Line and mainstream STM32G051 and STM32G061 MCUs add rich analog features and up to 18 KB of RAM, with package options up to 48 pins. In addition, the STM32G0B0 Value Line, STM32G0B1 and STM32G0C1 MCUs integrate a USB 2.0 device/host controller and dual-bank Flash memory. The STM32G0B1 and STM32G0C1 feature ST’s FDCAN peripheral.

With the variants that combine a USB 2.0 Full Speed crystal-less data interface supporting Device and Host modes, and a USB-C Power Delivery controller, STM32G0 allows users to develop innovative use-cases leveraging dual-role capability to extend the interoperability of USB-C devices. Now that USB Dual Role is replacing USB On-The-Go (OTG), the series can easily change between device and host roles and change between power source and power sink with a simple USB Power Delivery command. The FDCAN block provides two CAN 2.0 interfaces and supports CAN FD to help integrate innovative functionality in industrial systems and automotive diagnostics.

With these latest additions, the series now covers package options from eight to 100 pins, Flash density from 16 to 512 KB, and generous program-data RAM up to 144 KB. Flexible run and static modes enable low power consumption, up to the maximum operating frequency of 64 MHz. The internal clock is stable over temperature, and there is a precision timer with resolution proportional to twice the CPU frequency. The MCUs have high noise immunity and are available in various temperature ratings up to 125°C.

Cybersecurity features provide protection for consumer, appliance and industrial applications, including secure boot and firmware update (SB/SFU), proprietary code read-out protection (PCROP) to protect manufacturers’ IP and a memory protection unit (MPU) to assist task partitioning.
