MC9S08QA2CPAE集成電路（IC）的微控制器規(guī)格書PDF中文資料

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

– 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
