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)

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

Flash read/program/erase over full operating voltage and temperature

Flash size:

— MC9S08QD4/S9S08QD4: 4096 bytes

— MC9S08QD2/S9S08QD2: 2048 bytes RAM size

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 Read Microprocessor IC Freescale MC9S08QD4

— MC9S08QD4/S9S08QD4: 256 bytes

— MC9S08QD2/S9S08QD2: 128 bytes edge/level modes

Input/Output

Power-Saving Modes

· Wait plus three stops

Clock Source Options

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.

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.

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

System Protection

Development Support

(COP) reset with option to run from dedicated 32 kHz internal clock source by

· Single-wire background debug interface

Low-voltage detection with reset or interrupt

Illegal opcode detection with reset

Illegal address detection with reset

8-pin SOIC package

8-pin PDIP (Only for MC9S08QD4 and MC9S08QD2)

All package options are RoHS compliant
