Product Summary

The STM8S103K3T6CTR is a microcontroller. The STM8S103K3T6CTR offers 8 Kbytes Flash program memory, plus integrated true data EEPROM. The STM8S103K3T6CTR refers to devices in this family as low-density. It provides the following benefits: performance, robustness, and reduced system cost. Device performance and robustness are ensured by advanced core and peripherals made in a state-of-the art technology, a 16 MHz clock frequency, robust I/Os, independent watchdogs with separate clock source, and a clock security system.

Parametrics

STM8S103K3T6CTR absolute maximum ratings: (1) Supply voltage: -0.3V to 6.5V; (2) Input voltage on true open drain pins: VSS-0.3V to 6.5V; (3) Input voltage on any other pin: VSS-0.3 to VDD+0.3V; (4) Variations between different power pins: 50mV; (5) Variations between all the different ground pins: 50mV.
