Product details

72 MHz Cortex-M3 with 384 KB Flash — what the density buys you

The STM32F103RDT6: It packages 51 general-purpose I/O lines, a 16-channel 12-bit ADC, and a 2-channel 12-bit DAC, plus a CANbus interface and USB connectivity — a peripheral set that targets industrial control, motor-drive, and aftermarket automotive applications where a single-chip controller needs both sensor acquisition and fieldbus communication. The 384 KB Flash is the mid-density option in the STM32F103 line, suitable for a real-time control stack with a communication protocol plus a bootloader.

Peripheral set and package

The STM32F103RDT6 includes DMA, multiple PWM timers with dead-time insertion for motor control, a temperature sensor, and a watchdog — the usual STM32F103 complement.

Frequently asked questions

Can STM32F103RDT6 replace STM32F103C8T6?

Both are STM32F103 parts with the same ARM Cortex-M3 core and peripheral set, but they differ in package and pin count: the STM32F103RDT6 is in a 64-LQFP with 51 I/O, while the STM32F103C8T6 is a 48-LQFP with 37 I/O. They are not pin-compatible — a board designed for the C8T6 would need a layout change to use the RDT6.
