Overview

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.

Features

Features have been organized to reflect:

• Standard features of the HCS08 Family

• Features of the MC9S08GB/GT MCU

Standard Features of the HCS08 Family

• 40-MHz HCS08 CPU (central processor unit)

• HC08 instruction set with added BGND instruction

• Background debugging system (see also the Development Support section)

• 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)

Features of MC9S08GB/GT Series of MCUs

• On-chip in-circuit programmable FLASH memory with block protection and security options (see Table 1-1 for device specific information)

• On-chip random-access memory (RAM) (see Table 1-1 for device specific information)

• 8-channel, 10-bit analog-to-digital converter (ATD)

• Two serial communications interface modules (SCI)

• Serial peripheral interface module (SPI)

• Clock source options include crystal, resonator, external clock or internally generated clock with precision NVM trimming

• Inter-integrated circuit bus module to operate up to 100 kbps (IIC)

• One 3-channel and one 5-channel 16-bit timer/pulse width modulator (TPM) modules with selectable input capture, output compare, and edge-aligned PWM capability on each channel. Each timer module may be configured for buffered, centered PWM (CPWM) on all channels (TPMx).

• 8-pin keyboard interrupt module (KBI)

• 16 high-current pins (limited by package dissipation)

• Software selectable pullups on ports when used as input. Selection is on an individual port bit basis. During output mode, pullups are disengaged.

• Internal pullup on RESET and IRQ pin to reduce customer system cost

• 56 general-purpose input/output (I/O) pins, depending on package selection

• 64-pin low-profile quad flat package (LQFP) — MC9S08GBxx

• 44-pin quad flat package (QFP) — MC9S08GTxx

• 42-pin shrink dual in-line package (SDIP) — MC9S08GTxx
