1. A dedicated ordering information scheme will be released if, in the future, memory
programming service (FastROM) is required. The letter "P" will be added after STM8S.
Three unique letters identifying the customer application code will also be visible in the
codification. Example: STM8SP903K3MACTR.
2. UFQFPN, TSSOP, and SO packages.
3. LQFP package.
