AVXX32E -A SERIES
3, 7, 14 Seconds Complicate Pure Speech
Features
y Operating voltage: 2.4V~5.0V
y One single-key can implement play-all,
play-next and random function.
y Maximum play count is 16.
y Each input can implement looping function.
y Single-key input can be last-key priority for
stand-alone input or first-key priority.
y Each input trigger can select trigger mode: (For
OKY, TG0, TG1, TG3) Edge/Level, Hold/Unhold,
Retrigger/Irretrigger.
y Each input trigger can select its own debounce
time:
Fast debounce: < 200us;
Slow debounce: ~16ms (S.R.=6.0kHz)
y Support bouncing trigger solution for retrigger
application. (Second trigger force to retrigger
and slow debounce.)
y Maximum table entries are 204*4.
y Word count is only limited by ROM capacity.
y 3 output ports for Status or LED application:
Ϋʳ OP_A Status:
Busy_high, DC_low, Stop_high,DC_high
LED: +Fast,+Slow, Dyn(7/10), Off
Ϋʳ OP_B Status:
Busy_high, DC_low, Stop_high, DC_high
LED: -Fast, -Slow, Dyn(9/10), On
Ϋʳ OP_C Status: Busy_high, DC_low,
Busy_low, DC_high
LED: +Fast, +Slow, On, Off
y Each output can specify its initial state (High or
Low)
y Outputs can be set as constant current
regardless of the supply voltage varied.
y Two PWM playing ports. Drive speaker or
buzzer directly.
y Body define: 3, 7, 14 seconds. (Total ROM size :
18k,42k,84k)
y voice length(3s body:16384*5,7s
body:40960*5,14s body:83968*5)
y Voice algorithm: 5-bits LOG_PCM
y External resister for system frequency
y Sixteen default sampling frequencies are
supported. The default frequencies can be
changed by applying an external resistor.
y Support single key play on/off. (For OKY, TG0,
TG1)
y Programmable only pull-low input. (For
OKY,TG3)
y Programmable pull-high, pull-low or floating
input. (For TG0,TG1)
y 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.
