MC9S08QG4 Datasheet | Freescale Semiconductor

Features 8-Bit HCS08 Central Processor Unit (CPU) - - - - 20-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) Debug module containing two parators and nine trigger modes. Eight deep FIFO for storing change-of-flow addresses and event-only data Debug module supports both tag and force breakpoints Support for up to 32 interrupt/reset sources Peripherals - ADC - 8-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 ACMP - Analog parator module with option to pare to internal reference; output can be optionally routed to TPM module SCI - Serial munications interface module with option for 13-bit break capabilities SPI - Serial peripheral interface module IIC - Inter-integrated circuit bus module TPM- 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 MTIM - 8-bit modulo timer module with 8-bit prescaler KBI - 8-pin keyboard interrupt module with software selectable polarity on edge or edge/level modes - - - - - - - Memory Options - - FLASH read/program/erase over full operating voltage and temperature MC9S08QG8 - 8 Kbytes FLASH, 512 bytes RAM MC9S08QG4 - 4 Kbytes FLASH, 256 bytes RAM - - Power-Saving Modes - Wait plus three stops Input/Output - 12 general-purpose input/output (I/O) pins, one input-only pin and one output-only pin; outputs 10 m A each, 60 m A max 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 Clock Source Options -...
