## 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
