W58300

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 Proprietary synthesis algorithm Direct drive speaker by PWM output or by 8-bit DAC with external transistor Wide operating voltage range: 2.4−5.5 Volts Addressing capability up to 16M bits IR interface for command Transmission and Receiving 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/lab...
