FAQ

What is the maximum operating frequency and core type of the STM32G0B1KCT6?

The STM32G0B1KCT6 features an Arm Cortex-M0+ core rated for up to 64 MHz operation. It includes a Memory Protection Unit (MPU) and executes instructions with single-cycle GPIO toggle capability. The core supports Thumb-2 instruction set and achieves 0.91 DMIPS/MHz, validated across the full –40°C to 105°C temperature range specified for this part.

Does the STM32G0B1KCT6 support crystal-less USB operation?

Yes, the STM32G0B1KCT6 integrates a factory-trimmed 48 MHz internal RC oscillator (HSI48) qualified for USB 2.0 Full-Speed device operation without an external crystal. This oscillator meets USB specification jitter requirements (<±0.25% tolerance) and is automatically calibrated using the LSE or HSE clock source, enabling simplified PCB layout and reduced BOM cost.

How many FDCAN controllers does the STM32G0B1KCT6 include, and what standard do they comply with?

The STM32G0B1KCT6 integrates two fully independent FDCAN controllers compliant with ISO 11898-1:2015 (CAN FD). Each supports bit rates up to 5 Mbit/s, programmable data field lengths (up to 64 bytes), and flexible message filtering. They operate concurrently on separate CAN transceivers and share no register conflicts, enabling dual-bus architectures or redundancy schemes.

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

The STM32G0B1KCT6 supports Sleep, Stop (0/1/2), Standby, and Shutdown modes. In Standby mode with RTC and backup registers active, typical current consumption is 0.25 µA at 25°C (VDD = 3.3 V). This mode retains RTC calendar, 32 backup registers, and wakes via EXTI lines, RTC alarm, or tamper event - verified per DS13560 Rev 6 electrical characteristics table 33.
