Overview

The STM8S003F3U6TR is a cost-optimized 8-bit microcontroller from STMicroelectronics Value Line, offering 8KB of Flash memory and a 16MHz core frequency. It features a robust Harvard architecture, a 128-byte true data EEPROM, and essential peripherals in a compact 3x3mm UFQFPN20 package. This MCU is designed for high-volume, cost-sensitive applications where low pin count and basic processing power are required.

Why Choose This Part

This MCU provides a highly competitive price-to-performance ratio with integrated features like a clock security system and individual peripheral clock gating. Its small 20-pin UFQFPN footprint is ideal for space-constrained PCBs while still providing 16 available I/Os.

Applications

Simple Sensor Nodes
Utilizing the 10-bit ADC and I2C/SPI interfaces to collect and transmit environmental data.
Small Household Appliances
Managing user interface buttons, LED indicators, and basic timing functions for consumer goods.
Motor Control Support
Providing secondary control logic or PWM signal generation in simple brushed DC motor drivers.
Lighting Control
Driving LED dimming circuits and handling serial communication for lighting automation modules.
