STM8S Slide 10

The clock system allows fast switching from the internal high speed or low speed RC oscillators and an external crystal so performance and power efficiency can be optimized. A clock security system plus the two watchdogs increase system robustness. The factory calibrated internal high speed oscillator can be user trimmed for greater accuracy – in many cases removing the need for an external crystal. Additionally, a robust reset circuit has no grey areas which ensures that the device is safely in its operating range. I/Os have high injection current immunity – less than 1µA with 4mA on an adjacent pin making the STM8S ideal for industrial or other noisy environments. The fast 20 MIPs core is complemented by the advanced debug module. The 4 KB to 128 KB Flash memory can be programmed as a byte, word, or block. The true EEPROM memory is guaranteed to 300 K cycles. Furthermore, programming and debugging requires just a single pin using the Single Wire Interface.
