GENERAL DESCRIPTIONThe ISD2100is a digitalChipCorder®providing single-chip storage and playback of high quality audio. The device features digital de-compression, comprehensive memorymanagement, flash storage,and integrated audio signal path and Class D speaker drivercapable of delivering power of 400mW. This familyutilizes  flash  memory  to  provide  non-volatile  audio  playback  with  duration  up  to 30  seconds (based on 8kHz/4bitADPCMcompression)for a single-chip audio playback solution. The  ISD2100  can  be  controlled  and  programmed  through  an  SPI  serial  interface  or  operated  stand-aloneby triggers applied to the device’s  six GPIO pins.The  ISD2100  requires  no  external  clock  sources  or  components  except  a  speaker  to  deliver  quality audio prompts or sound effects to enhance user interfaces.In  addition  the  part  can  provide  non-volatile  flash  storage  in  1Kbyte  sectors  eliminating  the  need  for additional serial EEPROM/Flash devices.Compared to previousChipCorder series, this device provideshigher sampling frequencies, improved SNR, lower power, fast programming  time and integrated program verification.FEATURESDuration oISD2130–30 seconds based on 8kHz/4bit ADPCM in 1Mbit of flash storageoISD2115A–15seconds based on8kHz/4bit ADPCM in 1Mbit of flash storageAudio Management  oStore pre-recorded audio (Voice Prompts) using high quality digital compressionoUsesimple index based command for playback–no address needed.oExecute pre-programmed macro scripts (Voice Macros) designed to control the configuration of the device and playback Voice Prompts sequences.ControloSerial SPI interface for microprocessor control and programming.oStand-alone control where customized Voice Macro scripts are assigned to GPIO trigger pins.Sample Rateo7sampling frequencies 4, 5.3, 6.4, 8, 12.8, 16 and32kHzare available.oEach Voice Prompt can have optimal sample rate.Compression Algorithmsoμ-Law: 6, 7 or 8 bits per sampleoDifferential μ-Law: 6, 7 or 8 bits per sampleoPCM: 8, 10 or 12 bits per sampleoEnhanced ADPCM: 2, 3, 4 or 5 bits per sampleoVariable-bit-rate optimized compression.This allows best possible compression given a metric of SNR and background noise levels.Oscillator oInternal oscillator with internal reference: factory trimmed to ±1% deviationat room temperature. OutputoPWM: Class D speaker driver to direct drive an 8Ω speaker or buzzer.oDelivers 400mW at 3V supply.I/OsoSPI interface: MISO, MOSI, SCLK, SSB for commands and digital audio datao6 general purpose I/O pins multiplexed withSPI interface.Flash Storageo1Mbit (ISD2130) or 512Kbit (ISD2115A) of storage for combined audio/data.oFast programming time (20...
