Ordering information
1. The package pitch digit is used only when several dimensions are available for the same
2. A dedicated ordering information scheme will be released if, in the future, memory
package.
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.
