Features

8-bit HCS08 Central Processor Unit (CPU)

  • Up to 40 MHz HCS08 CPU (20 MHz bus frequency) for 50 ns minimum instruction time
  • HC08 instruction set with added BGND instruction
  • Support for up to 32 interrupt/reset sources

Integrated Third-Generation Flash Memory and RAM

  • Embedded flash that is in-application reprogrammable
  • Fast, byte-writable programming, as fast as 20 µs/byte
  • Up to 100,000 write/erase cycles at typical voltage and temperature (10k minimum write/erase)
  • 100 years typical data retention (15 years minimum)

Flexible Clock Options

  • Internal clock source (ICS) module containing a frequencylocked loop (FLL) controlled by internal or external reference
  • Precision trimming of internal reference allows typical 0.1 percent resolution and +0.5 percent to -1 percent deviation over operating temperature and voltage
  • Internal reference can be trimmed from 31.25 kHz to 39.065 kHz, allowing for 16 MHz to 20 MHz FLL output
  • Low-power oscillator module (XOSC)
    • software selectable crystal or ceramic resonator range, 31.25 kHz to 38.4 kHz or 1 MHz to 16 MHz,
    • supports external clock source input up to 40 MHz

Input/Output

  • Up to 23 bidirectional lines
  • One Output-Only Line
  • Outputs 10 mA each; 60 mA max for package
  • Software selectable pull-ups on ports when used as input
  • internal pull-up on reset and interrupt request (IRQ) pin
  • Software selectable slew rate control and drive strength on ports when used as output
  • 8-pin keyboard interrupt module with software selectable polarity on edge or edge/level modes

Ganged Output Option for PTB (5:2) and PTC (3:0)

  • Allows single write to change state of multiple pins
  • Drives up to 80 mA without risk of runaway code shorting
  • Provides option to tie multiple pins from different ports to same control registers
  • Safely drives multiple outputs

Multiple Serial Communication Options

  • Serial communications interface module with option for 13-bit break capabilities and double-buffered transmit and receive
  • Serial peripheral interface module and I²C bus module

Integrated Analog Peripherals

  • 16-ch., 10-bit analog-to-digital converter (ADC)
    • Automatic compare function, software programmable for greater than/equal to or less than conditions
    • Asynchronous clock source
    • Temperature sensor
    • Internal bandgap reference channel
    • Hardware triggerable using the RTI counter
    • Low-power and high-speed options
  • Analog comparator module (ACMP)
    • Option to compare to internal reference
    • Option to route comparator output directly to pin
    • Output can be optionally routed to TPM module as input capture trigger
  • Real-time-counter (RTC)
    • 8-bit modulus counter with binary or decimal based prescaler
    • External clock source for prescise time base, time-of-day, calendar or task scheduling functions

Three Timer Modules

  • Programmable 16-bit timer/PWM modules (TPM1 and TPM2)
  • 8-bit modulo timer module (MTIM) with 8-bit prescaler

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
  • Illegal opcode detection with reset
  • Flexible block protection
  • Security feature for flash and RAM
  • Always-on power-on reset (POR) circuitry

Development Support

  • Background Debugging System
  • On-Chip In-Circuit Emulation (ICE)
  • Real-Time Bus Capture
