Product details

72 MHz Cortex-M3 with 1 MB Flash — what the memory tier buys you

The STM32F103RGT6JTR: High-density memory option in the STM32F103 line with 1 MB Flash and 96 KB RAM.

For new designs, the STM32F103 series has been superseded by the STM32G4 families, though the pin-compatible STM32F103RGT6 (non-JTR suffix) may still appear in surplus inventory — verify the exact marking and date code.

The 64-LQFP (10x10 mm) package with 0.5 mm pitch demands careful decoupling — place a 100 nF ceramic per VDD pair within 3 mm of the pin, and a 4.7 µF bulk cap near the analog supply (VDDA).

Frequently asked questions

What is the difference between STM32F103RGT6 and STM32F103RGT6JTR?

The STM32F103RGT6 and STM32F103RGT6JTR share the same die and functional specifications — 72 MHz Cortex-M3, 1 MB Flash, 96 KB RAM, 64-LQFP. The 'JTR' suffix indicates Tape & Reel (TR) packaging, while the non-JTR variant typically ships in trays or tubes. Electrically and pin-compatible, the difference is only the shipping medium.
