W58300
Voice Synthesizer
(ROM-LESS High Fidelity
PowerSpeech
TM
)
Publication Release Date: March 1999
- 1 - Revision A2
GENERAL DESCRIPTION
The High Fidelity
PowerSpeech
TM
family is a new member of the
PowerSpeech
TM
synthesizer series,
with voice quality which is even better than before. The W58300 is a ROMless chip that can support
up to maximal 16M bits memory size; the voice length can reach 8.5 minutes. Combined with flash
memory W55Fxx, this chip can be used to demonstrate real chip function before mass-production.
This family has adopted the same architecture as the
PowerSpeech
TM
synthesizers while replacing
the 4-bit ADPCM algorithm with Winbond
′
s high fidelity synthesis algorithm to produce better quality
voice. W58300 provides hardware Infrared(IR) circuit, CPU interface and voice output in D/A
converter (DAC) or PWM type.
