The W523Sxx’ s LOAD, JUMP, MOVE and INC commands and ten programmable registers provide powerful user-programmable functions that make this chip suitable for an extremely wide range of speech IC applications. The W523Sxx family includes 14 kinds of bodies which are the same except for the voice duration shown below: PART NO.

W523S70 70 sec. W523S80 80 sec. W523S99 W523M02 100 sec. 120 sec. Note: The voice duration is estimated by 6.4 KHz sampling rate. FEATURES • Operating voltage range: 2.4 – 5.5 volts for both DAC and PWM output • New high fidelity synthesis algorithm • Either PWM mode or D/A converter mode can be selected for AUD output • Provides 4 direct trigger inputs that can easily be extended to 24 matrix trigger inputs • Two trigger input debounce times (50 mS or 400 uS) can be set • Provides up to 2 LEDs and 5 STOP outputs • Flexible functions programmable through the following: − LD (Load), JP (Jump), MV (Move) and INC (Increase) commands − Four general purpose registers: R0, R1, R2 and R3 − Six special purpose registers: EN0, EN1, MODE0, MODE1, STOP and PAGE − Conditional instructions: @LAST, @TGn_HIGH or LOW, where, n = 1,2,5 or 6 − Speech equations − END instruction • Supports CPU interface operation • Symbolic compiler supported • Instruction cycle ≤ 400 µS typically • Section control for − Variable frequency: 4.8/6/8/12 KHz Publication Release Date:Oct. 2000 - 1 - Revision A5 W523SXX (PRELIMINARY) − LED: ON/OFF • Up to 256 voice groups can be used in single page mode; or extended to 2,048 voice groups in multi page mode, such as 8-page, 16-page and 32-page.

All of these I/O pins’ status can be easily defined by PowerSpeech™ program. Powerful programmable features: The W523Sxx family provides JUMP (JP), LOAD (LD), MOVE (MV), INC, and END commands and 10 programmable registers, such as R0 ~ R3, EN0, EN1, MODE0, MODE1, STOP and PAGE, can be easily used to program the desired playing mode, stop output signal form, LED flash type, and trigger pin interrupt modes. The chip’ s programmable features can also be used to develop new, customized functions for a wide variety of innovative applications. Programmable Power-on Initialization: Whenever the W523Sxx is powered on or pressed the RESET pin, the program contained in the 32nd voice group will be executed after the power-on delay (about 160 mS), so the user can write a program into this group to set the power-on initial state. If user does not wish to execute a program at Publication Release Date: Oct 2000 - 3 - Revision A5 W523SXX (PRELIMINARY) power-on, an “ END” instruction should be entered in the group 32. The interruption priority is shown as below while other trigger pins as well as JUMP (JP) command are executing simultaneously during POI executing period: POI > TG1F > TG1R > TG2F > TG2R > TG5F > TG5R > TG6F > TG6R > "JP" instruction. Register Definition and Control The register file in the W523Sxx family is composed of 10 registers, including 4 general-purpose registers and 6 special purpose registers. They are defined to facilitate the operations for various purposes. The default setting values of the registers are given in the following table. REGISTER NAME DEFAULT SETTING General Register R0-R3 00100000B Special Register EN0 XX11XX11B EN1 XX11XX11B MODE0, MODE1 11111111B STOP XXX11111B PAGE.
