STMicroelectronics adds to STM32G0 Series with CAD FD and USB-C full speed
USB-C full speed dual role port, CAN FD, and larger memory variations have been added to the STM32G0 Arm Cortex-M0+ microcontrollers by STMicroelectronics.
For budget-conscious applications, the STM32G050 Value Line and mainstream STM32G051 and STM32G061 MCUs add rich analogue features and up to 18kBytes of RAM, with package options up to 48 pins. All of the new MCUs introduce new features to the STM32G0 series with integrated USB 2.0 device/host controller and dual-bank flash memory. The STM32G0B1 and STM32G0C1 also feature ST’s FDCAN peripheral.
The latest additions to the STM32G0 series combine a USB2.0 full speed crystal-less data interface supporting device and host modes, and a USB-C Power Delivery (PD) controller. The STM32G0 is designed to leverage dual role capability to extend the interoperability of new USB-C devices. As USB Dual Role is replacing USB on-the-go (OTG), STM32G0 can 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.
ST also offers the Nucleo-G0B1RE development board and STM32G0C1E-EV evaluation board. The company’s STM32CubeG0 software package provides the hardware abstraction layer (HAL), low layer (LL) APIs, and middleware components.
With these latest additions, the STM32G0 series now covers package options from eight to 100 pins, flash density from 16 to 512kbytes, and generous program data RAM up to 144kbytes. Flexible run and static modes ensure low power consumption, up to the maximum operating frequency of 64MHz. The internal clock is extremely stable over temperature, says St, and there is a precision timer with resolution proportional to twice the CPU frequency. STM32G0 MCUs have high noise immunity and are available in a range of temperature ratings up to 125degrees C.
Cyber-security features protect consumer, appliance and industrial applications, with 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. Variants with accelerated AES-256 hardware encryption are also available.
The STM32G0 devices are in production now.
