ISD-T360SB General Description
The VoiceDSP™ product family combines multiple digital signal processing functions on a single chip for cost-effective solutions in telephony, automotive and consumer applications.
The VoiceDSP processor offers necessary features to modern telephony products, such as: high-quality, speech record and playback, electrical and acoustic echo cancellation for full-duplex hands-free speakerphone operation.
The ISD-T360SB VoiceDSP can be used in various applications:
` Digital telephony with add-on speech processing: Digital Telephone Answering Machines(DTADs); and full-duplex, handsfree speakerphone operation for ISDN, DECT, Digital Spread Spectrum, and analog cordless applications; CT0/1 Base stations.
` An add-on chip for corded telephones featuring DTAD functions and/or fullduplex, hands-free speakerphone operation.
` Stand-alone digital answering machines with full-duplex, hands-free speakerphone operation.
` Voice memo recording
` Automotive applications employing fullduplex speakerphone operations for hands-free, in-car communications, and for car status and information announcements.
Based on ISD's unique concept which combines 16-bit DSP (Digital Speech Processor) and 16-bit RISC core technology, the ISD-T360SB is a highperforming chip solution for various applications. To facilitate incorporating the VoiceDSP processor,it features system support functions such as an interrupt control unit, codec interface (master,slave), Microwire interface to the system micro controller,as well as a memory handler for Flash and DRAM memory devices. Design of high-end, price optimized systems are possible with ISD's VoiceDSP flexible system interfaces (codec, microcontroller, and memory management support).
The ISD-T360SB processor operates as a peripheral controlled by the system microcontroller via an enhanced, serial Microwire interface. The system microcontroller typically controls the analog circuits, buttons and display, as well as activates functions through commands. The VoiceDSP executes these commands and returns status information to the Microcontroller.
The VoiceDSP software resides in the on-chip ROM. It includes DSP-based algorithms, system support functions, and a software interface to hardware peripherals.
ISD-T360SB Maximum Ratings
| Storage temperature | 65 to +150 |
| Temperature under bias | 0 to +70 |
| All input and output voltages with respect to GND | 0.5 V to +6.5 V |
NOTE Absolute maximum ratings indicate limits beyond which permanent damage may occur. Continuous operation at these limits is not intended; operation should be limited to the conditions specified below.
