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 feature including 4-bit ALU, 1K15 bits ROM, 644 bits
RAM, I/O port, timer, clock generator, LCD driver, etc. The instruction set with 78 instructions.
With the half function can minimize power dissipation.

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: 102415 bits
Internal RAM: 644 bits
8. Two 4-bit input ports (
AU1564, AU1564A has no S4 pad)
9. Two 4-bit I/O ports
10. One 4-bit output port
11. One control output pins
12. 78 instructions
13. 4-level subroutine nesting (also used for interrupt)
14. Two external factors (INT, S & M port) for interrupt
15. Two internal factors (Timer , Divider) for interrupt
16. Three current output level 1.5mA, 3mA, 4.5mA is mask option (full scale).
(
AU1564, AU1564A has no COUT output function)

Voice Trigger:
The voice circuitry will be Triggered in the rising edge of TRG signal. The Voice section address must be placed on I/OA
and I/OB port.
I/OB2 I/OB1 I/OA4 I/OA3 I/OA2 I/OA1
(MSB) (LSB)
a) In power on state, TRG signal is reset to "LOW" level. TRG will stay at low level until the program set it to "HIGH" level.
b) Before triggering the voice circuitry, used the OIOA and OIOB instruction to place the voice section address on I/OA and
I/OB port. The voice section address couldn't be changed until the rising edge of TRG signal.
c) After triggering voice, I/OA and I/OB ports must output 3F data or set to input mode. If not, there will be a standby
current problem.
d) Example of playing voice subroutine:
Triggering the 26th(1Ah) section
LDS 3,1
LDS 4,A
OIOB 3 ; place voice section address to i/o port
OIOA 4
RF 4 ; trigger voice
SF 4
LDS 3,3
LDS 4,F
OIOA 4 ; output 3F data to I/O port
OIOB 3
