MC9S08QD4 Series Features

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
