Peripherals
•
•
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
•
•
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
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.
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
System Protection
