AVXX32E-B SERIES

21, 32, 43, 65 and 87 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 32.

4-column inputs and 3-row outputs can

implement 4x4-matrix function.

Each input can implement looping function.

Single-key and 4-column inputs can be last-key

priority for stand-alone input or first-key priority.

Each input trigger can select trigger mode: (For

OKY, TG0, TG1, TG2, 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 460*8.

Word count is only limited by ROM capacity.

4 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

OP_D Status0: Busy_high, DC_low

Status1: Busy_low, DC_high

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 (For tone only).

One DAC playing port, together with external

bipolar to drive speaker. Ramp up/down is

automatic.

For DAC,

AVXX32E-B series supports 8

levels of current control to offer flexible choises

of corresponding BJT.

Four-level volume control is provided for DAC or

PWM output.

Eight-pitch control is provided.

Voice length: 21, 32, 43, 65 and 87 seconds.

(ROM capacity : 131072*5, 196608*5, 262144*5,

393216*5 and 524288*5 bits)

Voice algorithm: 5-bits LOG_PCM

External resister or built-in resister for system

frequency by bonding option on the same pad.

Sixteen default sampling frequencies are

supported. The default frequencies can be

changed by an external applying resistor.

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

TG1)

Programmable pull-high, pull-low or floating

input. (For OKY, TG0, TG1)

General Description

The

AVXX32E-B is a series of single-chip

synthesizing CMOS VLSI 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-B series able to best fit most

speech applications and a best cost/performance ratio

as a result.

The programming of the

AVXX32E-B

series is first to define words. Each word contains

voice data (or mute length), output method, pitch (if

pitch control enabled), and volume (if volume control

enabled). Assemble the words into sentences first,

and then the programmer can assign the sentences

to the keys corresponding to the user inputs.

The I/O pins of the

AVXX32E-B series are

multiplexed. This means the users have flexible I/O

options for their applications in a minimum number of

pin counts, that is, lower cost. The users can use

maximum 4*4 matrix plus one single-key inputs, but

less outputs; or 4 maximum outputs, but less inputs.

The

AVXX32E-B series support DAC or

PWM audio output, the users can select both if

necessary.

The frequency stability in the

AVXX32E-B

series is outstanding. The frequency variation by

voltage change is relatively small compared to the

competitor. Furthermore, volume option offers users

flexible selection for their applications. In addition, the

AVXX32E-B series support current control for

DAC output. Thus users can choose suitable current

output for their BJT component.

The programming and the approval can be done in

the EV chip of the

AVXX32E-B series. It

makes the programming and verification easy.
