Product details

1 MB Flash, 96 KB SRAM — the high-density STM32F103 option

This is the high-density variant in the STM32F103 value line, offering the largest on-chip memory footprint in the family for firmware-heavy applications like industrial motor drives, field-oriented control, CANopen gateways, and USB-capable instrumentation.

Motor-control peripheral set and connectivity

The peripheral list includes dedicated motor-control PWM timers, DMA, and a temperature sensor, alongside CAN, USB, SPI, I²C, and UART/USART interfaces. For a sensorless BLDC drive, the PWM timers and DMA can handle the commutation and current-sense sequencing in hardware, freeing the core for the control loop.

This means no last-time-buy window to manage and no forced redesign for obsolescence in the near term.

TR suffix — tape-and-reel delivery

The base part STM32F103RGT6 (tray) and this TR variant are electrically identical; the difference is only the shipping medium.

Frequently asked questions

What is the difference between STM32F103RGT6 and STM32F103RGT6TR?

The STM32F103RGT6 ships in tray packaging, while the STM32F103RGT6TR is the tape-and-reel variant. The silicon, firmware, and electrical ratings are identical. Choose the TR suffix for automated assembly lines that feed from reels.

What is the flash size of STM32F103RGT6TR?

The program memory is 1 MB of Flash, organized as 1M x 8 bits. This is the largest Flash density available in the STM32F103 value-line family.
