3 / 198 page 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 MC9S08QD4 Series Features |
