24C04 256x8(2k) Serial CMOS EEPROM
 
Description
 
 aP89021 high performance Voice OTP is fabricated with Standard CMOS process with embedded 512K bits EPROM. It can store up to 21sec voice message with 4-bit ADPCM compression at 6KHz sampling rate.8-bit PCM is also available as user selectable option.Two trigger modes,simple Key trigger mode and Parallel CPU trigger mode facilitate different user interface. User selectable triggering and output signal options provide maximum flexibility to various applications. Built-in resistor controlled oscillator, 8-bit current mode D/A output and PWM direct speaker driving output minimize the number of external components. PC controlled programmer and developing software are available.
 
Features
  • 16 PIN DIP
  • Standard CMOS process
  • Embedded 512KB EPROM
  • 21 sec voice length at 6KHz sampling rate and 4-bit ADPCM compression
  • Maximim 12 vocie groups
  • Combination of voice building blocks to extend playback duration
  • 960 table entries are available for voice block combinations
  • User selectable PCM or ADPCM data compress
  • Two trigger modes are available by whole chip option during voice compilation. Key Trigger Mode - combinations of S1 ~ S4 to trigger up to 12 voice groups, SBT for sequential trigger. CPU parallel trigger mode - combinatios of S1 ~ S4 with SBT goes HIGH to strobe start the voice playback
