The 8 KB Flash holds a bootloader, ADC channels, a UART parser, and a PWM routine.
The 20-TSSOP package gives you 18 I/O lines, a 10-channel 12-bit ADC, and serial interfaces including I²C, SPI, and UART.
For dual-sourcing resilience, the STM8L151x3 family shares the same pinout and peripheral set, so a swap to a sibling density variant (e.g., 16 KB Flash) is a firmware recompile away.
