The MC9S08AW60CPUE is a 8-bit General-purpose Microcontroller based on enhanced HCS08 CPU (20MHz bus) with CISC architecture operates at a maximum frequency of 40MHz. The device incorporates 60kB internal flash, 2kB internal RAM, 16-channel 10-bit A/D converter and 54 general-purpose I/O pins. This device also features peripherals like one inter-integrated circuit (IIC) bus module to operate at up to 100kbps, one serial peripheral interface modules (SPI), two serial communications interface (SCI) modules and real-time counter (RTC). Breakpoint capability to allow single breakpoint setting during in-circuit debugging (plus two more breakpoints in on-chip debug module). On-chip real-time in-circuit emulation (ICE) with two comparators (plus one in BDM), nine trigger modes and on-chip bus capture buffer.
