H8 Super Low Power Series Line-up

H8 Super Low Power Series

■ Features

• Multiple techniques minimize power consumption

and extend battery life

– Low-power CMOS technology for 1.8V operation

– Up to 9 Low-power modes

– 32 kHz on-chip sub-clock oscillator

– Peripheral-independent standby mode

• Advanced analog interfaces such as 14-bit

Delta-Sigma converter

• Shorter oscillation stabilization time lets applications

wake up faster from standby mode, conserving power

• LCD controller with built-in voltage booster circuit

eliminates need for external DC/DC converter

• High current port for driving LEDs directly

• 16-bit asynchronous counter (AEC) operates even

when device is in standby mode

• Low cost development tools using on-chip debug
