40 MHz core, 2.7-5.5 V supply, -40 to +125°C
The S9S08SG16E1MTL: The 40 MHz clock rate is adequate for control-loop tasks like motor commutation timing or LIN-bus gateway polling. At 125°C the flash retention and leakage margins are specified — no derating curve needed for engine-bay or hot-enclosure deployment.
On-chip peripherals: ADC, PWM, LIN, SPI, I²C
A 16-channel 10-bit ADC reads analog sensors directly. The PWM module drives actuators or generates variable-frequency outputs. Connectivity includes I²C, LINbus, SCI (UART), and SPI — enough for a mixed-signal control node on a single die. Built-in LVD (low-voltage detect), POR (power-on reset), and WDT (watchdog timer) handle brownout and code-wander recovery without external supervisor ICs. The internal oscillator eliminates the crystal for most applications.
