{"product_id":"stm8s903f3m3tr","title":"STM8S903F3M3TR","description":"\u003cp\u003eThe STM8S903F3M3TR is a tape-and-reel version of the STM8S903F3M3 microcontroller from STMicroelectronics. It features the same 8-bit STM8 core at 16 MHz, 8 KB of flash, and 1 KB of RAM in a 20-SOIC package. Operating from 2.95V to 5.5V, it includes brown-out detection and a watchdog timer for dependable operation. This variant is specifically packaged for automated pick-and-place manufacturing, reducing assembly costs for high-volume projects.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTape-and-Reel Packaging:\u003c\/strong\u003e Streamlines SMT assembly, reducing production time and cost.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProven STM8 Core:\u003c\/strong\u003e Offers a mature, stable architecture with extensive development tools.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Safety Features:\u003c\/strong\u003e POR, BOR, and WDT provide fail-safe operation without external components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Supply Range:\u003c\/strong\u003e Compatible with both 3.3V and 5V systems, increasing design flexibility.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eAutomated Assembly Lines\u003c\/h3\u003e\u003cp\u003eThe tape-and-reel packaging (TR) is optimized for high-volume SMT production, making this variant ideal for mass-produced control modules.\u003c\/p\u003e\u003ch3\u003eConsumer Appliances\u003c\/h3\u003e\u003cp\u003eUse it in washing machine timers or microwave control panels.
