STM32G0 Arm Cortex-M0+ MCU product
Dual Bank Flash, CAN FD, Crystallis
Added support for USB Full Speed Device/Host


STMicroelectronics announced on the 29th that it has expanded the STM32G0 Arm® Cortex®-M0+ MCU series with rich features and product lines, including dual-bank flash, CAN FD, and crystal-less USB full-speed device/host support.

The new STM32G050 Value Line and key products, the STM32G051 and STM32G061 MCUs, have added package options of up to 48 pins, various analog functions, and up to 19KByte of RAM to support cost-sensitive applications. Additionally, the STM32G0B1 and STM32G0C1 feature ST's FDCAN peripherals.

The STM32G0 is a new product that combines a USB-C PD (Power Delivery) controller, enabling customers to develop innovative use cases while utilizing Dual-Role (DR) capabilities that extend the interoperability of new USB-C devices. Currently, USB DR is replacing USB OTG (On-The-Go). To this end, the STM32G0 uses simple USB PD commands to change the power source and sink, and allows the device and host roles to be easily switched.

In addition, the FDCAN block provides two CAN 2.0 interfaces and supports CAN FD to integrate innovative features into industrial systems or automotive diagnostic devices.

ST supports the NUCLEO-G0B1RE board and the STM32G0C1E-EV evaluation board. In addition, it provides Hardware Abstraction Layer (HAL) and Low-Layer (LL) APIs and middleware components through the STM32CubeG0 software package.

The STM32G0 series supports package options ranging from 8 to 100 pins, flash capacities from 16 to 512 KB, and up to 144 KB of program data RAM. It guarantees low power consumption up to an operating frequency of 64 Hz. It also provides a high-precision internal clock that is stable relative to temperature, as well as precision timers with resolution proportional to twice the CPU frequency. The STM32G0 MCU features high noise immunity and can be used in various temperature classes up to 125°C.

In addition, features such as Secure Boot and Firmware Update (SB/SFU) for manufacturer IP protection, Proprietary Code Read-Out Protection (PCROP), Memory Protection Unit (MPU) supporting task partitioning, and AES-256 encryption are provided.

The price of the 32KB flash TSSOP20 package STM32G050F6P6 Value Line is $0.47. The 512KB flash LQFP32 package STM32G0B0KET6 is $1.21 for a purchase of 1,000 units. The NUCLEO-G0B1RE Nucleo-64 board is $10.32, and the STM32G0C1E-EV is $304.
