Read Microprocessor IC Freescale MC9S08QD4

We can CRACK MCU Freescale Semiconductor MC9S08QD4 8-Bit HCS08 Central Processor Unit (CPU), please view the microcontroller chip features for your reference:


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


· Support for up to 32 interrupt/reset sources



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


— MC9S08QD4/S9S08QD4: 256 bytes

— MC9S08QD2/S9S08QD2: 128 bytes


edge/level modes


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
