MC9S08QA2
Features:
• 8-bit HCS08 Central Processor Unit (CPU)
– Up to 20 MHz CPU at 3.6 V to 1.8 V across temperature
range of –40°C to 85°C
– HC08 instruction set with added BGND instruction
– Support for up to 32 interrupt/reset sources
• On-Chip Memory
– Flash read/program/erase over full operating voltage
and temperature
– Random-access memory (RAM)
– Security circuitry to prevent unauthorized access to
RAM and flash contents
• Power-Saving Modes
– Two very low power stop modes
– Peripheral clock enable register can disable clocks to
unused modules, thereby reducing currents
– Very low power real time counter for use in run, wait,
and stop modes with internal clock sources
• Clock Source Options
– Internal Clock Source (ICS) — Internal clock source
module containing a frequency-locked-loop (FLL)
controlled by internal reference; precision trimming of
internal reference allows 0.2% resolution and 2%
deviation over temperature and voltage; supports bus
frequencies from 1 MHz to 10 MHz
• System Protection
– Watchdog computer operating properly (COP) reset
with option to run from dedicated 1 kHz internal clock
source or bus clock
– Low-voltage detection with reset or interrupt
– Selectable trip points
– Illegal opcode detection with reset
– Illegal address detection with reset
– Flash block protection
• Development Support
– Single-wire background debug interface
8-Pin DFN
Case 1452-02
8-Pin NB-SOIC
Case 751-07
8-Pin PDIP
Case 626-06
– Breakpoint capability to allow single breakpoint setting
during in-circuit debugging
• Peripherals
– ADC — 4-channel, 10-bit resolution; 1.7 mV/°C
temperature sensor; automatic compare function;
internal bandgap reference channel; operation in stop3;
fully functional from 3.6 V to 1.8 V
– ACMP — Analog comparator with selectable interrupt
on rising, falling, or either edge of comparator output;
compare option to fixed internal bandgap reference
voltage; output can be tied internally to TPM input
capture
– TPM — One 1-channel timer/pulse-width modulator
(TPM) module; selectable input capture, output
compare, or buffered edge- or center-aligned PWM on
each channel; ACMP output can be tied internally to
input capture
– MTIM — 8-bit modulo timer module with 8-bit
prescaler
– KBI — 4-pin keyboard interrupt module with software
selectable polarity on edge or edge/level modes
• Input/Output
– Four GPIOs, one input-only pin and one output-only
pin.
– Hysteresis and configurable pullup device on all input
pins; configurable slew rate and drive strength on all
output pins except PTA5
• Package Options
– 8-pin SOIC, PDIP, and DFN
