MC9S08QB4 Datasheet | Freescale Semiconductor

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 - Up to 8 KB flash memory read/program/erase over full operating voltage and temperature - Up to 512 bytes random-access memory (RAM) - Security circuitry to prevent unauthorized access to RAM and flash contents Power-Saving Modes - Two very low power stop modes - Low power run and low power wait modes - Peripheral clock enable register can disable clocks to unused modules, thereby reducing currents - Very low power external oscillator that can be used in stop2 or stop3 modes to provide accurate clock source to real time counter - 6 μs typical wakeup time from stop3 mode Clock Source Options - Oscillator (XOSC) - Loop-control Pierce oscillator; crystal or ceramic resonator range of 31.25 k Hz to 38.4 k Hz or 1 MHz to 16 MHz - 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 puter operating properly (COP) reset with option to run from dedicated 1 k Hz 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 - 8-channel, 12-bit resolution; 2.5 μs conversion time; automatic pare function; 1.7 m V/°C temperature sensor; internal bandgap reference channel; operation in stop3; fully functional from 3.6 V to 1.8 V. - ACMP - Analog parator with selectable...
