ISD-T360SA
VoiceDSPTM Digital Speech Processor with CID, CID on Call Waiting (CIDCW), Full-Duplex Speakerphone, Master/Slave CODEC Interface and Multiple Flash Support --Advance Information--
The VoiceDSPTM 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: highquality speech record and playback, electrical and acoustic echo cancellation for full-duplex hands-free speakerphone operation. The VoiceDSP Caller ID Type I feature complies with the Bellcore (US), French, Spanish, Dutch and Japanese standards. For the Bellcore (US) standard, the VoiceDSP implements CID Type II. The VoiceDSP implements the receiver side for data transmitted from the central office to the subscriber. The T360SA VoiceDSP can be used in various applications: * Digital telephony with add-on speech processing: Digital Telephone Answering Machines (DTADs), hands-free 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 full-duplex, 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 handsfree, 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-T360SA 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 microcontroller, as well as a memory handler for Flash 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-T360SA 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.

For optimal noise immunity, the power and ground pins should be connected to VCC and the ground planes, respectively, on the printed circuit board. If VCC and the ground planes are not used, single conductors should be run directly from each VCC pin to a power point, and from each GND pin to a ground point. Avoid daisy-chained connections. The VoiceDSP does not perform its usual functions in power-down mode but it still preserves stored messages, maintains the time of day. When you build a prototype, using wire-wrap or other methods, solder the capacitors directly to the power pins of the VoiceDSP processor socket, or as close as possible, with very short leads.

MEMORY INTERFACE
Flash Support
The ISD-T360SA VoiceDSP supports Flash devices for storing recorded data, thus, power can be disconnected to the ISD-T360SA without losing data. The ISD-T360SA supports NAND Flash device interfaces, such as TC58V16BFT, TC5816BFT, TC58A040F, KM29N040T, KM29W8000T, and KM29W16000AT. The ISD-T360SA may be connected to up to four Flash devices, resulting with maximum recording storage of 16-Mbits x 4 = 64 Mbits (up to 4 hours of recording time). The following flash devices are supported:

Internal Memory Organization
The Flash devices detailed in Table 1-4 divide internally into basic 4-Kbyte block units. The ISD-T360SA uses one block on each device for memory management, leaving the rest of the blocks available for recording. Using at least one block for a single recorded message yields a maximum of NUM_OF_BLOCKS_IN_MEM - 1 (see Table 2-10 for parameter definition) messages per device.

Table 2-7: TUNABLE PARAMETERS: Tone Detection
Index 20 Parameter Name Busy and Dial Tone: TONE_DET_OFF_ENERGY_ THRESHOLD Description
2--SOFTWARE
Default
Maximum energy level at which busy and dial tones are detected 110 as OFF (after 700Hz filtering). If you divide (multiply) the value by 2 you get about 3 dB decrease (increase) in the threshold. The mapping between energy level and the parameter value is the same as for TONE_DET_ON_ENERGY_THRESHOLD Legal values: 0 to 65535. Minimum time period for busy detection, in 10 ms units. The accuracy of the constant is 10 ms. Legal values: 0 to 65535. Minimum period considered as On period for busy tone detection. Note that for weak signals: (-30 dB and below) the maximum value is 12 (i.e., 120 ms minimum detection time). Unit: 10 ms. Accuracy is 20 ms. Legal values: 10 to 1000. Maximum period considered as On for busy-tone detection. Unit: 10 ms. Accuracy is 20 ms. Legal values: 10 to 1000. Minimum period considered as Off for busy-tone detection. Unit: 10 ms. Accuracy is 20 ms. Legal values: 5 to 1000. Maximum period considered as On for busy-tone detection. Unit: 10 ms. Accuracy is 20 ms. Legal values: 5 to 1000. Number of On/Off cadences that must be detected prior to reporting busy-tone presence. Legal values: 9 to 127. Specifies the type of busy tone to detect: 1 --Two cadences 2 --Three cadences 3 --Both two and three cadences The maximum allowed difference between two compared On or Off periods. Unit: 10 ms. Legal values: 0 to 255. 600
