W58300
Voice Synthesizer
(ROM-LESS High Fidelity PowerSpeech )TM
GENERAL DESCRIPTION
The High Fidelity PowerSpeechTM family is a new member of the PowerSpeechTM 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 PowerSpeechTM 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.
FEATURES
• Programmable voice synthesizer

• TX, INC and MV instruction provided
• 8 trigger inputs - with separate control of falling/rising edge trigger
• 8 STOP outputs
• Supports CPU interface operation
• Pad option for Ring or Crystal oscillator
• Symbolic compiler supported
• Instruction cycle ≤ 400 µS typically
• Section control
− Variable frequency: 4.8/6/8/12 KHz
− LED: ON/OFF
• Eight general-purpose registers R0−R7
• Number of interrupt vector/label up to 2,048

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.

0: IR Output Without Carrier
MODE1.5 is for LED flash type control. MODE1.4 is for LED1 section control ON/OFF. MODE1.3 is
for LED2 Section/STPC control. MODE1.2 is for LED1 volume control. MODE1.0 is for IR output with
or without carrier and this bit is useful only MODE0.5 is "1". For STPC control IR output (MODE0.5 is
0), the IR output always has 38 KHz carrier signal no matter what the setting of MODE1.0 is.
