3 / 198 page

8-Bit HCS08 Central Processor Unit (CPU)

•

16 MHz HCS08 CPU (central processor

unit)

•

HC08 instruction set with added BGND

instruction

•

Background debugging system

•

Breakpoint capability to allow single

breakpoint setting during in-circuit

debugging (plus two more breakpoints in

on-chip debug module)

•

Support for up to 32 interrupt/reset sources

Memory

•

Flash read/program/erase over full

operating voltage and temperature

•

Flash size:

— MC9S08QD4/S9S08QD4: 4096 bytes

— MC9S08QD2/S9S08QD2: 2048 bytes

•RAM size

— MC9S08QD4/S9S08QD4: 256 bytes

— MC9S08QD2/S9S08QD2: 128 bytes

Power-Saving Modes

•

Wait plus three stops

Clock Source Options

•

ICS — Internal clock source module (ICS)

containing a frequency-locked-loop (FLL)

controlled by internal. Precision trimming

of internal reference allows 0.2% resolution

and 2% deviation over temperature and

voltage.

System Protection

•

Watchdog computer operating properly

(COP) reset with option to run from

dedicated 32 kHz internal clock source or

bus clock

•

Low-voltage detection with reset or

interrupt

•

Illegal opcode detection with reset

•

Illegal address detection with reset

•

Flash block protect

Peripherals

•

ADC — 4-channel, 10-bit analog-to-digital

converter with automatic compare

function, asynchronous clock source,

temperature sensor and internal bandgap

reference channel. ADC is hardware

triggerable using the RTI counter.

•

TIM1 — 2-channel timer/pulse-width

modulator; each channel can be used for

input capture, output compare, buffered

edge-aligned PWM, or buffered

center-aligned PWM

•

TIM2 — 1-channel timer/pulse-width

modulator; each channel can be used for

input capture, output compare, buffered

edge-aligned PWM, or buffered

center-aligned PWM

•

KBI — 4-pin keyboard interrupt module

with software selectable polarity on edge or

edge/level modes

Input/Output

•

Four General-purpose input/output (I/O)

pins, one input-only pin and one

output-only pin. Outputs 10 mA each, 60

mA maximum for package.

•

Software selectable pullups on ports when

used as input

•

Software selectable slew rate control and

drive strength on ports when used as output

•

Internal pullup on RESET and IRQ pin to

reduce customer system cost

Development Support

•

Single-wire background debug interface

Package Options

•

8-pin SOIC package

•

8-pin PDIP (Only for MC9S08QD4 and

MC9S08QD2)

•

All package options are RoHS compliant
