Description



Features:

• Programmable speech synthesizer
• Wide operating voltage range: 2.4 to 5.5 volts
• 4-bit ADPCM synthesis method
• Provides 4 direct trigger inputs that can easily be extended to 8 or 12 matrix trigger inputs
• Two trigger input debounce times (20 to 40 mS or 160 to 320 S) can be set
• Provides up to 2 LEDs and 3 STOP outputs
• Every LED pin can drive 3 LEDs simultaneously
• LED flash frequency: 3 Hz
• AUD output current: 5 mA
• Flexible functions programmable through the following:
− LD (load), JP (jump) commands
− Four registers: R0, EN, STOP, and MODE
− Conditional instructions
− Speech equation
− END instruction
− Global repeat (GR) setting
− Output frequency and LED flash type setting
• Programmable power-on initialization (POI) (can be interrupted by trigger inputs)
• POI delay time of 160 mS ensures stable voltage when chip is powered on
• Can be programmed for the following functions:
− 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)
− Four playing modes:
One Shot (OS)
Level Hold (LH)
Single-cycle level hold (S_LH)
Complete-cycle level hold (C_LH)
− Stop output signal setting
− Serial, direct, or random trigger mode setting
• Four frequency options (4/4.8/6/8 KHz) and LED On/Off control can be set independently in each GO instruction of speech equation
• Independent control of LED1 and LED2
• Total of 256 voice group entries available for programming
• Provides the following mask options:
− LED flash type: synchronous/alternate
− LED1 section-controlled: Yes/No
− LED2: section-controlled/STPC-controlled
− LED volume-controlled: No/Yes
