STM8S003F3P6

16 MHz STM8S value-line 8-bit MCU with 8 KB Flash, 1 KB RAM, and 128-byte true data EEPROM, integrating a 10-bit ADC, three timers, and UART/SPI/I²C interfaces in a TSSOP-20 package, ideal for cost-sensitive control boards, appliance control, and general embedded designs.

Product Description

Product Overview

The STM8S003F3P6 belongs to ST’s STM8S003F3 value line, focusing on cost-effective 8-bit control solutions. It uses a 16 MHz STM8S core with Harvard architecture and a three-stage pipeline plus nested interrupt controller and multiple timers to deliver solid real-time performance at low system cost.

It integrates 8 KB of Flash, 1 KB of RAM, and 128 bytes of true data EEPROM with up to 100k write/erase cycles, ideal for frequently-updated parameters and calibration data. Internal 16 MHz and 128 kHz RC oscillators, brown-out reset, and POR help eliminate external components and shrink BOM cost.

Packaged in TSSOP-20 (tube), it exposes up to 16 I/Os including 5 channels of 10-bit ADC, operates from 2.95 to 5.5 V over –40°C to +85°C, and fits legacy 5 V systems, white goods, small appliances, simple industrial controllers, and educational boards.
