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
– Flash read/program/erase over full operating voltage and
temperature
– Random-Access memory (RAM)
– Security circuitry to prevent unauthorized access to RAM and
flash contents
• Power-Saving Modes
– Two low power stop modes
– Reduced power wait mode
– Low power run and wait modes allow peripherals to run while
voltage regulator is in standby
– Peripheral clock gating 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 wake-up time from stop3 mode
• Clock Source Options
– Oscillator (XOSC) — 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
or external reference; precision trimming of internal reference
allows 0.2% resolution and 2% deviation over temperature and
voltage; supporting 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 warning with interrupt
– Low-Voltage detection with reset or interrupt
– 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 (plus two more breakpoints in on-chip debug
module)
– On-Chip in-circuit emulator (ICE) debug module containing two
comparators 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

• Peripherals
– ADC — 10-channel, 12-bit resolution; 2.5 μs conversion time;
automatic compare function; 1.7 mV/°C temperature sensor;
internal bandgap reference channel; operation in stop3; fully
functional from 3.6 V to 1.8 V
– ACMPx — Two analog comparators with selectable interrupt on
rising, falling, or either edge of comparator output; compare
option to fixed internal bandgap reference voltage; outputs can be
optionally routed to TPM module; operation in stop3
– SCI — Full-Duplex non-return to zero (NRZ); LIN master
extended break generation; LIN slave extended break detection;
wake-up on active edge
– SPI — Full-Duplex or single-wire bidirectional; double-buffered
transmit and receive; master or slave mode; MSB-first or
LSB-first shifting
– IIC — Up to 100 kbps with maximum bus loading; multi-master
operation; programmable slave address; interrupt driven
byte-by-byte data transfer; supporting broadcast mode and 10-bit
addressing
– TPMx — Two 3-channel (TPM1 and TPM2); selectable input
capture, output compare, or buffered edge- or center-aligned
PWM on each channel
– RTC — (Real-time counter) 8-bit modulus 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 (1 kHz) for cyclic wake-up
without external components; runs in all MCU modes
• Input/Output
– 26 GPIOs, one output-only pin and one input-only pin
– Eight KBI interrupts with selectable polarity
– Hysteresis and configurable pullup device on all input pins;
configurable slew rate and drive strength on all output pins.
• Package Options
– 32-pin LQFP, 28-pin SOIC, 20-pin SOIC, 16-pin PDIP,
16-pin TSSOP
