HT81012, HT81R03 Datasheet - Holtek Semiconductor

HT81012 EasyVoice Speech

The EasyVoiceTM is a single-chip voice synthesizer LSI . The chip when triggered drives a speaker directly or through an external transistor with a PWM output. Negligible current is consumed in the standby state. The HT81xxx provides direct key or Matrix key input and 2 programmable FLAG outputs. Wi.

HT81012 Features

* Operating voltage: 2.4V~5V

* Directly drives an external transistor

* PWM function directly driver speaker

* Low standby current (1mA typ. for VDD=3V)

* Minimal external components

* 240 notes table ROM for key functions

* Programmable silence length and end-pulse width
