STMicroelectronics STM32G0B1CCU3TR

Overview

STM32G0B1CCU3TR from STMicroelectronics is a 32-bit Arm® Cortex®-M0+ microcontroller with 512 KB flash, 144 KB SRAM, dual 12-bit DACs, two FDCAN controllers, and USB Type-C™ Power Delivery controller - deployed in industrial HMI, smart metering gateways, and USB-C PD-enabled embedded power systems.

For engineers reviewing the STM32G0B1CCU3TR datasheet, STM32G0B1CCU3TR pinout, STM32G0B1CCU3TR application, or STM32G0B1CCU3TR equivalent, key selection criteria include its 64 MHz CPU frequency, 94 fast I/Os (including 5 V-tolerant), dual FDCAN support for automotive-grade networking, and integrated USB-C PD controller enabling single-cable power + data negotiation.

Technical Context

The STM32G0B1CCU3TR integrates an Arm Cortex-M0+ core with MPU, supporting up to 64 MHz operation and hardware parity on 128 KB of its 144 KB SRAM. Its memory subsystem includes dual-bank flash with read-while-write capability and securable area for firmware IP protection.

It features a comprehensive clock system: 4–48 MHz HSE crystal oscillator, 32 kHz LSE with calibration, 16 MHz HSI (±1%), and 48 MHz HSI48 RC for USB FS timing - all managed via programmable PLL and voltage regulator scaling across Sleep/Stop/Standby modes.

Key Specifications

Pinout & Package

STM32G0B1CCU3TR is housed in a 48-pin Ultra-Fine Pitch Quad Flat No-lead (UFQFPN48) package, 7 mm × 7 mm, 0.5 mm pitch, exposed thermal pad - optimized for thermal dissipation and high-density layout in industrial and portable applications.

FAQ

What is the maximum operating frequency and voltage range of the STM32G0B1CCU3TR?

The STM32G0B1CCU3TR operates at up to 64 MHz using its Arm Cortex-M0+ core and supports a supply voltage range of 1.7 V to 3.6 V. Its I/Os tolerate up to 5 V when configured in FT (5 V-tolerant) mode, and it includes separate VDDA/VSSA pins for analog circuitry to maintain ADC/DAC accuracy across the full voltage range.

Does the STM32G0B1CCU3TR support USB-C Power Delivery negotiation without external components?

Yes - the STM32G0B1CCU3TR integrates a complete USB Type-C™ Power Delivery controller including CC line transceivers, VBUS discharge circuitry, policy engine, and physical layer. It performs source/sink role detection, voltage/current contract negotiation, and fault monitoring without requiring external PD controller ICs or level shifters.

How many FDCAN interfaces does the STM32G0B1CCU3TR provide, and what standards do they meet?

The STM32G0B1CCU3TR includes two fully independent FDCAN controllers compliant with ISO 11898-1:2015. Each supports Classical CAN and CAN FD frames, bit rates up to 5 Mbit/s in FD mode, and time-triggered communication - enabling dual-network isolation in automotive body control or industrial automation gateways.

What low-power modes are available, and what is the typical current draw in Shutdown mode?

The STM32G0B1CCU3TR supports Sleep, Stop, Standby, and Shutdown modes. In Shutdown mode with RTC and backup registers active, typical current consumption is 150 nA at 25°C (VDD = 3.3 V). This mode retains VBAT-supplied RTC timekeeping and 32 bytes of backup SRAM while disabling all clocks and regulators.
