The 20-UFQFPN package measures 3x3 mm, so it fits into compact designs like wearable health monitors, smart actuators, or single-cell battery devices where every square millimeter counts.
For dual-sourcing flexibility, the base product number STM8 covers a family of pin-compatible density variants — the same firmware can scale up to 8 KB Flash parts if the application grows.
The TR suffix indicates Tape & Reel packaging, while the base part number (without TR) typically ships in tube or tray. The silicon, firmware, and performance are identical.
