Revision A1
GENERAL DESCRIPTION
W583xxx are fabricated using the Winbond CMOS process. The W583xxx family is a new member of
the PowerSpeech
synthesizer series, with voice quality which is even better than before. The
W583xxx family has adopted the same architecture as the PowerSpeech
synthesizers while
replacing the 4-bit ADPCM algorithm with Winbond
s new high fidelity voice synthesis algorithm to
produce better quality voice. W583xxx provides IR function, CPU interface, pad option for Ring or
Crystal oscillator and voice output in DAC current or PWM type.
According different voice duration, there are 11 bodies in W583xxx family, list them below.

Notes:
1. The voice duration is estimated by 6.4 KHz sampling rate.
2. W583S10 provides less I/O pins, and do not provide crystal oscillator.

FUNCTIONAL DESCRIPTION
The W583xxx is a derivative of Winbond's PowerSpeech
synthesizers, which are becoming
dominant in the consumer market, especially for toy applications.
There are up to 8 trigger inputs and 8 STOP outputs in W583xxx. The maximal number of software
key pad by scanning matrix is up to 8
9 = 72 keys. There are 8 general purpose registers, R0-R7.
R0-R7 can apply not only for "LD" and "JP" instructions but also for "MV" instruction. Only R0 can
apply for "INC" instruction. CPU interface is the same as the W581xx series.
IR interface is a new feature of PowerSpeech
. User can use IR interface to transmit and receive a
command. For example, when X chip executes the "TX R1" instruction, the Pulse Position Modulation
waveform (with 38 KHz carrier) outputs from IROUT pin to drive a photo diode. Y chips within a
certain distance will receive the IR signal through an IR receiver module to TG3/IRIN pin and execute
a "JP" instruction to the interrupt vector/label pointed by R1 of X chip.
There are two kinds of events that can cause the W583xxx to enter the POI (Power On Initialization)
process: one is power on, and the other is direct trigger from RESET pin. The interrupt vector "32" is
allocated for this special event, and its priority is above all, i.e., no triggers can override the POI
process if they all happen simultaneously. So the user can write a program into this interrupt vector to
set the power on initial state. If the user does not wish to execute a program on power on, he should
write an "END" instruction in interrupt vector "32". During the POI process, triggers can then override
it successfully; if the EN0, EN1 and MODE0, MODE1 registers are set properly.
If more than two events happen simultaneously, the priority that is set by the internal H/W is: POI >
TG1F > TG1R > TG2F > TG2R > TG3F > TG3R > TG4F > TG4R > TG5F > TG5R > TG6F > TG6R
> TG7F > TG7R > TG8F > TG8R > "JP" instruction.

Register Definition And Control
The register file of the W583xxx family is composed of 14 registers, including 8 general purpose
registers and 6 special purpose registers.
They are defined to facilitate the operations for various purposes. The default setting values of the
registers are given in the following table.

MODE0.7 controls the output type of LED1 (and LED2) pin. MODE0.6 controls the configuration of
LED2/STPC pin. MODE0.5 controls the output source of IR. If hardware control IR output is selected,
IR output can have signal with carrier or without carrier which is selected by MODE1.0. MODE0.4
controls the trigger pin debounce time. MODE0.2 controls the behavior of the STPA/BUSY pin which
is usually used as Busy signal in CPU mode.
