Voice-audio IC Integrates Telephony Features

Mon, 07/12/2010 - 10:39am
voice-audio ICNuvoton Technology introduced its ChipCorder voice/audio device to enable telephony functions in commercial and consumer systems. The ISD61S00 provides a digital-audio interface, audio storage interface, macro-scripting ability, and streamlined programmability that allows designers to develop telephony-based systems with audio prompting, multi-language options, and fast, address-free recording and playback of up to 64 minutes. The IC 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 2.7 V, the ISD61S00 can perform 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.
