MC9S08QD2 Datasheet | Freescale Semiconductor

Features 8-Bit HCS08 Central Processor Unit (CPU) - Flash block protect - 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 Peripherals - ADC - 4-channel, 10-bit analog-to-digital converter with automatic pare 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 pare, 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 pare, 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 m A each, 60 m A 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 - Watchdog puter operating...
