Product details

The STM32F405RGT6W: It carries 1 MB of Flash and 192 KB of SRAM, enough for a full embedded TCP/IP stack, a CANopen fieldbus layer, and a local data logger without external memory.

Industrial temperature range and peripheral set — fit check for factory automation and outdoor telecom

The 51 I/O pins in the 64-LQFP package leave room for a parallel display bus plus a dozen discrete sensors.

On-chip data converters and oscillators — reducing BOM count

Sixteen 12-bit ADC channels and two 12-bit DAC channels are integrated. The internal oscillator can serve as the system clock for many applications, saving the cost of an external crystal.

Sourcing posture for this active MCU

STMicroelectronics lists this part as current production with an active lifecycle status.

Frequently asked questions

Does STM32F405RGT6W support CAN bus?

Yes.

What is STM32F405RGT6W's maximum operating frequency?

168 MHz, from the ARM Cortex-M4 core with FPU.

Is STM32F405RGT6W compatible with the STM32F4 Discovery board?

The STM32F4 Discovery board typically uses a larger package (100-pin LQFP) and a different part number. The STM32F405RGT6W in 64-LQFP shares the same Cortex-M4 core and peripheral set but has fewer I/O and a smaller footprint. Pin compatibility would require checking the specific Discovery schematic.
