The NXP MC9S08AC16CFJE is an 8-bit microcontroller built around the S08 core, running at 40 MHz.
Peripherals and I/O — what is on the die
On-chip peripherals include a 6-channel 10-bit ADC for direct sensor readout, plus LVD, POR, PWM, and WDT blocks. Connectivity covers I²C, SCI (UART), and SPI — enough for common serial interfaces to displays, sensors, or a host controller. The 22 I/O lines in the 32-LQFP package leave room for a mix of digital and analog inputs without needing port expanders.
