General Description

: The AU1564, AU1564A, AU2064, AU2064A is a single chip voice synthesizer with 4-bit microprocessor.

That can synthesize voice up to 15, 20 seconds by ALPHA qualified coding algorithm (LOGPCM).

The 4-bit microprocessor has various

Key Features

  • 1. Single power supply can operate from 2.4V through 6V 2. The total voice duration is about 15, 20 seconds could be partitioned up to 64 sections (AU1564, AU1564A -->15 seconds, AU2064, AU2064A -->20 seconds) 3. The voice can be triggered by microprocessor instructions 4. Current output could drive 8 ohm speaker with a transistor, VOUT could drive buzzer or 64 ohm directly. 5. LCD driver provided, up to 3× 24=72 segments. Build-in HALVER circuitry. 6. Build-in clock generator 7. Internal ROM:.
