Chapter 1 Introduction
1.1
The MC9S08GB/GT are members of the low-cost, high-performance HCS08 Family of 8-bit
microcontroller units (MCUs). All MCUs in the family use the enhanced HCS08 core and are available
with a variety of modules, memory sizes, memory types, and package types.

Standard features of the HCS08 Family
Features of the MC9S08GB/GT MCU
40-MHz HCS08 CPU (central processor unit)
HC08 instruction set with added BGND instruction
Background debugging system (see also
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.
Support for up to 32 interrupt/reset sources
Power-saving modes: wait plus three stops
System protection features:
— Optional computer operating properly (COP) reset
— Low-voltage detection with reset or interrupt
— Illegal opcode detection with reset
— Illegal address detection with reset (some devices don’t have illegal addresses)
On-chip in-circuit programmable FLASH memory with block protection and security options (see
Table 1-1
On-chip random-access memory (RAM) (see
8-channel, 10-bit analog-to-digital converter (ATD)
Two serial communications interface modules (SCI)
Serial peripheral interface module (SPI)
