MC9S08AW32CFGE Description

The MC9S08AW32CFGE is an 8-bit general-purpose microcontroller that runs at a maximum frequency of 40MHz and is based on an improved HCS08 CPU (20MHz bus). The chip includes 34 general-purpose I/O pins, an 8-channel 10-bit A/D converter, 32kB internal flash, and 2kB internal RAM. Additionally, this device includes peripherals including a real-time counter, two serial peripheral interfaces (SPI) modules, one inter-integrated circuit (IIC) bus module capable of operating at up to 100 kbps, and one SPI module (RTC). When conducting in-circuit debugging, breakpoint functionality permits the placement of a single breakpoint (plus two more breakpoints in the on-chip debug module). On-chip real-time in-circuit emulation (ICE) with nine trigger modes, an on-chip bus capture buffer, and two comparators (plus one in the BDM).
