H8 Tiny Series Line-up

H8 Tiny Series

■ Features

• High performance 16-bit CPU, with

eight 32-bit general-purpose registers

and 32-bit data processing

• Up to 20MHz operation

• On-chip flash for simplified production

programming or code update

• Flexible clocking scheme with multiple clock

sources and multiple levels of clock dividers

• Various 8- and 16-bit timers for advanced

waveform generations typically used in

motor control applications

• Multiple fail-safe features such as watchdog

timers with dedicated on-chip oscillator,

external oscillator fail detection, low-voltage

detection and Reset source detection

• High current port for driving LEDs directly

• High peripheral integration, including real-time

clock, up to sixteen A/D channels and a range

of communication interfaces

• System cost reduction with built-in power-on

reset circuitry, band-gap voltage regulators and

on-chip oscillators

• Low-cost development tools using on-chip debug

• Code and peripheral function compatibility with

other H8 microcontroller families
