| Preliminary W58100 ADPCM VOICE SYNTHESIZER ROM-LESS ENHANCED PowerSpeechTM GENERAL DESCRIPTION The W58100 is a CMOS IC that is used solely for the purpose of demonstrating the W581xx series enhanced PowerSpeechTM products. The W58100 employs the same JUMP-GO architecture as Winbond's other PowerSpeechTM products. Unlike standard products, however, the W58100 does not include built-in memory, because the chip is designed to serve only as a demonstration chip for the W581xx series ICs. Hence the W58100 must be operated with an external memory device (e.g., a flash EPROM memory IC). The W58100's LOAD and JUMP commands and 8 programmable registers provide powerful user-programmable functions that make this chip suitable for a wide range of speech IC applications. FEATURES * * * * * * * * Wide operating voltage range: 2.4 to 5.5 volts Serves as a demo chip for W581xx series products (no built-in ROM) Programmable speech synthesizer 4-bit ADPCM synthesis method and 8-bit D/A converter Maximum 4 trigger inputs Fading effect (patent pending) control for each voice segment Maximum two LEDs, and five STOP outputs Flexible functions programmable through the following: - LD (load), JP (jump) commands - 8 general registers: R0-R7 - Three special registers: EN, STOP, and MODE - Conditional instructions - Speech equation Programmable power-on initialization (POI), which can be interrupted by trigger inputs Interrupt or non-interrupt for rising or falling edge of each trigger pin (this feature determines retriggerable, non-retriggerable, overwrite, and non-overwrite features of each trigger pin) LED On/Off control can be set independently in each GO instruction of speech equations Independent control of LED 1 and LED 2 Total of 256 voice group entries available for programming (Including eight hardware and 248 software group entry points) CPU interface The following mask options are available: * * * * * * * -1- Publication Release Date: December 1996 Revision A1 Preliminary W58100 - LED flash type: synchronous/alternate - LED1 section-controlled: Yes/No - LED2 section-controlled/STPC-controlled - LED volume controlled: No/Yes - Normal/CPU mode - STPE or BUSY selection * The following register controls are available: - Trigger input debounce time: Long/Short - Pin option for LED2/STPC - LED turn-on mode: Flash/DC PIN CONFIGURATION TG1 TG2 TG3 TG4 LED1 STPB STPA NC SPK V SS 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 WRP DATA RDP STPE/BUSY STPD LED2/STPC RESET DISOTP OSC V DD -2- Preliminary W58100 PIN DESCRIPTION NO. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 NAME TG1 TG2 TG3 TG4 LED1 STPB STPA NC SPK VSS VDD OSC DISOTP RESET LED2/STPC STPD STPE/BUSY RDP DATA WRP I/O I I I I O O O O I I I O O O O I/O O Trigger Input 1 Trigger Input 2 Trigger Input 3 Trigger Input 4 LED 1 Stop signal B Stop signal A Not connected Current output for driving an external speaker Negative power supply Positive power supply Oscillation frequency control, connect Rosc to VDD Disable all of the serial interface pins (low active) Reset pin (low active) LED2 signal output or Stop C output Stop D output Stop E or Busy signal output Read pulse clock output for serial interface Bidirectional Data Pin for the serial interface Write pulse clock output for serial interface FUNCTION ABSOLUTE MAXIMUM RATINGS PARAMETER Power Supply Input Voltage Storage Temp.

In principle, the playing speed determined by ROSC should correspond to the sampling rate during the coding phase. However, the playing speed may be adjusted by varying ROSC. 2. RS is an optional current-dividing resistor. If RS is added, the resistance should be between 470 and 750. 3. R is used to limit the current on the LED. 4. CS is optional. 5. The DC current gain of transistor 8050 ranges from 120 to 200. 6. All unused trigger pins can be left open because of their internal pull-high resistance. 7. No warranty for production. -5- Publication Release Date: December 1996 Revision A1 Preliminary W58100 BONDING PAD DIAGRAM PAD NO. 17 18 11 19 1 2 3 4 5 6 7 Y PAD NAME TG1 TG2 TG3 TG4 LED1 STPB STPA SPK VSS VDD OSC DISOTP RESET 16 15 14 13 12 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 Note: Substrate is tied to VSS. 10 X (0, 0) 9 8 LED2/STPC STPD STPE/BUSY RDP DATA WRP Headquarters No. 4, Creation Rd.
