Nuvoton Introduces Industry’s First ChipCorder IC with Integrated Telephone Features New ChipCorder ISD61S00 Optimized for Telephony-based Systems

SAN JOSE, Calif.—10/15/2010—Nuvoton Technology Corp., a leading worldwide provider of semiconductors for consumer and computing applications, today introduced the industry’s first ChipCorder voice/audio device to enable proven telephony functions in commercial and consumer systems. The new ChipCorder® ISD61S00 provides a digital-audio interface, audio storage interface, powerful macro-scripting ability, and streamlined programmability that allow designers to develop telephony-based systems with audio prompting, multi-language options, and fast, address-free recording and playback of up to 64 minutes.

With its extensive array of audio features, the ISD61S00 helps system designers create a wide range of non-PC communication platforms, such as personal emergency response systems (PERS), docking stations, home security systems, point-of-sale (POS) terminals, telephone answering devices (TADs) and vending machines. Featuring an operating voltage as low as 2.7V, the versatile ISD61S00 can perform a range of powerful telephony-based communications functions, such as the detection and generation of both dual-tone multi-frequency (DTMF) signaling and frequency-shift keying (FSK) for Bell 103, Bell 202 or V.23 modem.

Additionally, the chip features a public switched telephone network (PSTN) interface, a customer alert signal (CAS) detector, CPT (call progress tone) detection, and ring detection. A system’s audio quality is enhanced by the ISD61S00’s echo-cancellation feature and pulse-code modulation/inter-IC sound (PCM/I2S) digital audio interface. The chip’s 16 general-purpose I/O (GPIO) pins are accessible through its serial peripheral interface (SPI) ports, easing designers’ task of programming systems. Furthermore, the ISD61S00’s telephony features enable dial-out alerts via residential telephone lines.

“ Given Nuvoton’s broad portfolio of advanced digital-audio devices, it was a natural and logical extension of our success to expand ChipCorder technology into a broader base of applications,” said Saleel Awsare, president, Nuvoton Technology Corp. America. “The ISD61S00 takes advantage of the ChipCorder’s highly integrated non-volatile voice and audio chip technology – known to and used by manufacturers worldwide -- and empowers system designers to blend that technology with distinct characteristics to deliver a new generation of telephony-based PERS, POS, security and other advanced systems.”

In addition to its recording, playback and programmability benefits, the ISD61S00 incorporates an unprecedented array of other features, including:

  • dual CODECs, providing connections to direct access arrangements (DAAs), speakers and microphones
  • audio path with acoustic and line-echo cancellation to implement full- and half-duplex speakerphone functions
  • higher sampling frequencies up to 16kHz
  • improved signal-to-noise ration (90dB (typical)
  • lower power dissipation (0.5W maximum)
  • operating voltage from 2.7V to 3.6V
  • record and playback compression, enabling duration from four to 64 minutes (based on 8kHz/4bit adaptive differential pulse-code modulation, or ADPCM)
  • analog audio input and output
  • message management
  • external flash memory interface ; and digital access to flash memory.

Availability, Pricing

The ISD61S00, available in a 48-pin LQFP package, is sampling now, with production scheduled for Q3 this year, at $3.00 in 10K quantities. For full technical details of the ISD61S00 and the entire Nuvoton ChipCorder family , visit:
