Preliminary W583XXX HIGH FIDELITY Power Speech TM
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. PART NO. Duration PART NO. Duration W583S10 10 sec W583S50 50 sec W583S15 15 sec W583S60 60 sec W583S20 20 sec W583S80 80 sec W583S25 25 sec W583S99 99 sec W583S30 30 sec W583M02 120 sec W583S40 40 sec
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 s.
