Key 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 ℃ to 85 ℃ – 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 Peripheral clock enable register can disable clocks to unused modules, thereby reducing currents – Low power run – Low power wait - 6 μs typical wakeup time from stop3 mode – Typical stop current of 250 nA at 3 V, 25 ℃
• Clock Source Options – Oscillator (XOSC) — Very low-power, loop-control Pierce oscillator; crystal or ceramic resonator range of 31.25 kHz to 38.4 kHz 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 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 — 8-channel, 12-bit resolution; 2.5 μs conversion time; automatic compare function; 1.7 mV/℃ temperature sensor; 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; operation in stop3 – 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 optional prescaler – RTC — (Real-time counter) 8-bit modulo counter with binary or decimal based prescaler; external clock source for precise time base, time-of-day, calendar or task scheduling functions; free running on-chip low power oscillator (Δ1kHz) for cyclic wakeup without external components; runs in all MCU modes – SCI — Full duplex non-return to zero (NRZ); LIN master extended break generation; LIN slave extended break detection; wakeup on active edge – KBI — 8-pin keyboard interrupt with selectable edge and level detection modes
• Input/Output – 18 GPIOs include one input-only 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.
