AVXX32E -A SERIES

3, 7, 14 Seconds Complicate Pure Speech

Features

Operating voltage: 2.4V~5.0V

One single-key can implement play-all,

play-next and random function.

Maximum play count is 16.

Each input can implement looping function.

Single-key input can be last-key priority for

stand-alone input or first-key priority.

Each input trigger can select trigger mode: (For

OKY, TG0, TG1, TG3) Edge/Level, Hold/Unhold,

Retrigger/Irretrigger.

Each input trigger can select its own debounce

time:

Fast debounce: < 200us;

Slow debounce: ~16ms (S.R.=6.0kHz)

Support bouncing trigger solution for retrigger

application. (Second trigger force to retrigger

and slow debounce.)

Maximum table entries are 204*4.

Word count is only limited by ROM capacity.

3 output ports for Status or LED application:

OP_A Status:

Busy_high, DC_low, Stop_high,DC_high

LED: +Fast,+Slow, Dyn(7/10), Off

OP_B Status:

Busy_high, DC_low, Stop_high, DC_high

LED: -Fast, -Slow, Dyn(9/10), On

OP_C Status: Busy_high, DC_low,

Busy_low, DC_high

LED: +Fast, +Slow, On, Off

Each output can specify its initial state (High or

Low)

Outputs can be set as constant current

regardless of the supply voltage varied.

Two PWM playing ports. Drive speaker or

buzzer directly.

Body define: 3, 7, 14 seconds. (Total ROM size :

18k,42k,84k)

voice length(3s body:16384*5,7s

body:40960*5,14s body:83968*5)

Voice algorithm: 5-bits LOG_PCM

External resister for system frequency

Sixteen default sampling frequencies are

supported. The default frequencies can be

changed by applying an external resistor.

Support single key play on/off. (For OKY, TG0,

TG1)

Programmable only pull-low input. (For

OKY,TG3)

Programmable pull-high, pull-low or floating

input. (For TG0,TG1)

TG3_OPC pin can option as input or output by

mask option

General Description

The AVXX32E -A are series of single-chip

synthesizing CMOS VLSI IC which synthesizes

voice by LOG_PCM algorithm. Table programming

and shared multiple I/O pins make the applications

flexible.

Powerful functions and pure speech architecture

make the AVXX32E -A series are able to best fit

most speech applications and a best

cost/performance ratio as a result.

The programming of the AVXX32E -A series is

first to define words. Each word contains voice data

(or mute length), output method, assemble the

words into sentences first, and then the programmer

can assign the sentences to the keys corresponding

to the user inputs.

The TG3_OPC pin of the AVXX32E -A series is

multiplexed. This means it can option as input pin or

output pin.
