FAQ
What is the maximum operating frequency and how is it achieved?
The STM32F412RGT6TR achieves 100 MHz CPU frequency using its Adaptive Real-Time Accelerator (ART Accelerator™), which caches Flash read accesses to eliminate wait states. This allows deterministic real-time execution directly from embedded Flash memory without requiring external high-speed RAM, reducing BOM cost and PCB footprint while maintaining full DSP instruction support and FPU throughput.
Does this MCU support USB device, host, and OTG functionality?
Yes - the STM32F412RGT6TR integrates a full-speed USB 2.0 OTG controller with built-in PHY, supporting device, host, and OTG roles. It includes dedicated PA11/PA12 pins for D−/D+, internal pull-up control, and hardware support for standard USB classes (CDC, HID, MSC). No external transceiver is needed for basic USB device or host operation, simplifying design for firmware updates or peripheral bridging.
How many CAN interfaces does the STM32F412RGT6TR provide, and what protocol versions are supported?
The STM32F412RGT6TR provides two independent bxCAN 2.0B controllers supporting both standard (11-bit) and extended (29-bit) identifier frames, with bit rates up to 1 Mbit/s. CAN1 uses PB8/PB9, and CAN2 uses PD0/PD1 - enabling dual-bus architectures for redundancy, diagnostics, or distributed control without external CAN bridge ICs or software arbitration overhead.
What low-power modes are available and what are their typical current draws?
The STM32F412RGT6TR supports Run (112 µA/MHz), Sleep, Stop (18–75 µA depending on Flash retention mode), and Standby (2.4 µA @25°C, 1.7 V). In Stop mode with Flash in Deep Power Down, it draws as low as 18 µA while retaining SRAM and register content, with wakeup in ≤3.5 µs via EXTI or RTC alarm - ideal for battery-powered sensor nodes requiring periodic measurement bursts.
