Features

8-bit HCS08 Central Processor Unit (CPU)

  • Up to 8 MHz S08 CPU for 125 ns minimum instruction time
  • HC08 instruction set with added background instruction
  • Support for up to 32 interrupt/reset sources
  • Supply voltage range of 2.7–5.5V

Integrated Third-Generation Flash Memory and RAM

  • Embedded flash that is in-application reprogrammable over the full operating voltage and temperature range with a single power supply

General Purpose Input/Output (GPIO) Lines

  • Outputs 10 mA each; 100 mA max for package
  • Four general-purpose input output (GPIO)
  • One input-only and one output-only line
  • 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
  • 4-pin keyboard interrupt module with software selectable polarity on edge or edge/ level modes
  • 1-ch. timer/pulse-width modulator; each channel can be used for input capture, output compare, buffered edge-aligned PWM or buffered center-aligned PWM
  • Software-selectable pull-ups on ports when used as input; internal pull-up
  • Software-selectable slew rate control and drive strength on ports when used as output
  • Single-wire background debug interface
  • 8-pin plastic dual-inline package (PDIP) and 8-pin narrow body small outline integrate circuit (SOIC) packages
  • Internal pull-up on reset and IRQ pin

Integrated Analog Peripherals

  • 4-ch., 10-bit ADC with automatic compare function
  • ADC channel connected to on-chip temperature sensor
  • 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 real-time interrupt counter
  • Low-power and high-speed options
  • Can be used for single slope APC and resistance-capacitance time
  • Easy interface to analog inputs/sensors
  • Used to set conversion complete and generate interrupt only when result matches condition

Flexible Clock Options

  • Internal clock source module containing a frequency-locked loop controlled by internal reference

Two Timer Modules

  • Programmable 16-bit timer/PWM (TPM) module
  • 2-ch. TPM; each channel can be used for input capture, output compare, buffered edge-aligned pulse width modulation (PWM) or buffered center-aligned PWM
  • 1 x 2-ch., 16-bit timer
  • 1 x 1-ch., 16-bit timer

System Protection

  • Watchdog computer operating properly 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 flash block protection
  • Security feature for flash and RAM
  • Always-on power-on reset circuitry
