Features:

• 8-Bit HCS08 Central Processor Unit (CPU)

– 20 MHz HCS08 CPU (central processor unit)

– 10 MHz internal bus frequency

– HC08 instruction set with added BGND

– Support for up to 32 interrupt/reset sources

•On-Chip Memory

– Up to 8 KB of on-chip in-circuit programmable flash memory with block protection and security options

– Up to 512 bytes of on-chip RAM

• Power-Saving Modes

– Wait plus two stops

• 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; supports bus frequencies from 1 MHz to 10 MHz.

• System Protection

– Optional computer operating properly (COP) reset with option to run from independent 1 kHz internal clock source or the bus clock

– Low voltage detection

– Illegal opcode detection with reset

– Illegal address detection with reset

• Development Support

– Single-wire background debug interface

– Breakpoint capability to allow single breakpoint setting during in-circuit debugging

• Peripherals 

– SCI— Full duplex non-return to zero (NRZ); LIN master extended break generation; LIN slave extended break detection; wakeup on active edge

– ADC — 10-channel, 10-bit resolution; 2.5 μs conversion time; automatic compare function; 1.7 mV/°C temperature sensor; internal bandgap reference channel; runs in stop3

– TPMx— One 2-channel (TPM1) and one 1-channel (TPM2) 16-bit timer/pulse-width modulator (TPM) modules; selectable input capture, output compare, and edge-aligned PWM capabilityon each channel; timer module may be configured for buffered, centered PWM (CPWM) on all channels

– KBI— 8-pin keyboard interrupt module

– RTC— Real-time counter with binary- or decimal-based prescaler

• Input/Output

– Software selectable pullups on ports when used as inputs

– Software selectable slew ratecontrol on ports when used as outputs

– Software selectable drive strength on ports when used as outputs

– Master reset pin and power-on reset (POR)

– Internal pullup on RESET, IRQ, and BKGD/MS pins to reduce customer system cost

• Package Options

– 28-pin PDIP

– 28-pin SOIC

– 16-pin TSSOP
