The STM8S003 is almost identical to the STM8S103, the only difference is a smaller EEPROM area:

STM8S003F3: https://www.st.com/en/microcontrollers-microprocessors/stm8s003f3.html

• Data memory: 128 bytes true data EEPROM; endurance up to 100 k write/erase cycles

STM8S103F3: https://www.st.com/en/microcontrollers-microprocessors/stm8s103f3.html

• Data memory: 640 byte true data EEPROM; endurance 300 kcycle

• STM8 eForth is an interactive Forth system for the STM8 family of highly reliable 8-bit MCUs with 16bit extensions and modern peripherals that are easier to master than those in 32bit µCs.
• • The STM8 eForth core is written in STM8 assembly using the SDCC tool chain. Combining Forth with C is supported.
