Product Details

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 (50 mS or 400 mS) 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
