The MC9S08AC16CFGE is a 8-bit Flexis Microcontroller based on enhanced HCS08 CPU (20MHz bus) with CISC architecture operates at a maximum frequency of 40MHz. The device incorporates 16kB internal flash, 1kB internal RAM, 8-channel 10-bit A/D converter and 34 general-purpose I/O pins. This device also features peripherals like one inter-integrated circuit (IIC) bus module to operate at up to 100kbps and one serial peripheral interface modules (SPI). Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus two more breakpoints in on-chip debug module). Debug module containing two comparators and nine trigger modes. Eight deep FIFO for storing change-of-flow addresses and event-only data. Debug module supports both tag and force breakpoints.
