STM8S903K3T6C

STM8S903K3T6C
Mainstream Application specific line 8-bit MCU with 8 Kbytes Flash, 16 MHz CPU, integrated EEPROM, LQFP32, STM, RoHS

The STM8S903K3 and STM8S903F3 8-bit microcontrollers offer 8 Kbytes Flash program memory, plus integrated true data EEPROM. The STM8S microcontroller family reference manual (RM0016) refers to the devices in this family as low-density. They provide the following benefits: performance, robustness, and reduced system cost.
