# STM8S003F3P6TR (Component)

## Description

8\-Bit Microcontroller \(MCU\) – General\-purpose STM8 microcontroller with 8 KB Flash, 1 KB RAM, and 128\-byte EEPROM, operating at up to 16 MHz\. The STMicroelectronics STM8S003F3P6TR operates from 2\.95 V to 5\.5 V and integrates I²C, SPI, UART/USART, LIN, and IrDA interfaces, a 10\-bit ADC with up to 5 channels, timers, PWM, watchdogs, and up to 16 I/O pins\. It is housed in a 20\-pin TSSOP package and supports −40°C to \+85°C operation\.
