whether you need your product to say a few words or talk for several minutes, sensory?s SC-6X speech and music processors can deliver a few seconds to several hours of speech. every sensory speech product is made with your design in mind. efficient technology allows you to cut costs and size by using smaller and fewer devices. a complete range of development tools and software helps you get your products to market faster. p owerful t echnology the SC-6X product family introduces a new world of speech synthesis opportunities. this family is built aro und a 12.32 million instructions per second (mips) digital signal processor (dsp) to enable advanced speech algorithms, yielding speech quality never before obtained at such low data rates. these dsps provide three low-power modes, two timer interrupts, one dac interrupt and five general-purpose interrupts. these feat ures increase battery life and speed of response to button and keyboard presses. sensory SC-6X employs three processing methods - cx, mx, lpc - that produce natural sounding speech while using a relatively small amount of memory. y our product?s quality will speak for itself. if your product needs music, sensory offers several choi ces, including simultaneous speech with high quality polyphonic music. a r ange of c hoices not only can you choose the optimum combination of pr ice and capacity, you can adopt any of these digital storage alternatives: on-chip mask progra mmable rom, external memory (sc-614 only). t ypes of s ynthesis memory required per minute of speech (kb) data rate kbps cx synthesis is your solution for producing lo ng durations of great speech and sound effects at the lowest possible system cost. mx offers data rates as low as 1k bits-per- second, yielding high quality speech with minimal development effort. 3.0~11.2 22.5~84.0 mx synthesis provides optimal speech and soun d effects. its highly sophisticated analysis can reproduce the subtle qualitie s of a broad range of character voices. cx offers up to six choices of data rates to help you optimize speech quality and memory cost. 1.0~3.5 7.5~26.2 lpc is mathematically simpler than mx or cx, requiring less processing power but more editing. 1.8 13.5 music synthesis sensory also provides a way to enhance your products with high quality music synthesis. sensory?s music synthesizer provides polyphonic music using standard musica l instrument digital interface (midi) files that have been converted into compact bitstreams. this gives the ability to play up to 14 channels of music. music + speech the music synthesizer can also play polyphonic music simultaneously with speech (mx or cx), adding even more excitement to your products. sc-6 x f amily s peech and m usic p rocessors product brief (80-0213-c)
sc-6 x f amily sc-601 the sc-601 has a 1.5 mb rom to support up to 24 minutes of internally-stored mx speech or up to 8 minutes of cx speech. sc-604 the sc-604 contains the same powerful core, rom and ram as the other SC-6X devices, but has a reduced i/o set and pin count which makes it the most economical of the SC-6X family members. sc-605 the sc-605 has a 2.36mb (288kb) rom to support up to 37 minutes of internally-stored mx speech or up to 12 minutes of cx speech. this device is a perfect one-chip system solution, functioning as master controller, speech processor, and data memory. sc-614 the sc-614 expands the capability of the SC-6X family by incorporating 64 i/o pins for interfacing with the outside world. it can also address up to 64mb of external memory, providing over 18 hours of speech duration! sc-691 the sc-691 is a pre-programmed slave synthesizer implemented on the SC-6X family line that accepts commands and compressed speech data from other microp rocessors or microcontrollers and converts it to speech output. since no SC-6X programming knowledge is ne eded, this is the simplest SC-6X family member to develop with. s peech s ynthesis d uration f or sc-6 x d evices 1 single-chip speech duration (8 khz sampling rate) speech algorithm mx cx compression rate (bps ) 1000 2400 3000 3700 4500 6200 7700 11200 sc-605 37min 15min 12min 9min 50sec 8min 5sec 5min 50sec 4min 45sec 3min 15sec sc-601 24min 10min 7min 45sec 6min 20sec 5min 10sec 3min 45sec 3min 2min 5sec sc-604/614 6min 30sec 2,40 min 2 min 1,35min 1min 20sec 55sec 45sec 30sec additional duration available by adding external memory (8 khz sampling rate) 4 mb rom or flash 1hr 9min 29min 23min 18min 15min 11min 9min 6min 10sec 8 mb rom or flash 2hr 19min 58min 46min 37min 31min 22min 18min 12min 16 mb rom or flash 4hr 39min 1hr 56min 1hr 33min 1hr 15min 1hr 2min 45min 36min 24min 64 mb rom or flash 9hr 19min 3hr 53min 3hr 6min 2hr 31min 2hr 4min 1hr 30min 1hr 12min 49min 1 these times are examples which assume a small (2kw ) control code, the exact speech duration depends on the size of the control code. 1991 russell avenue santa clara, ca 95054 tel 408.327.9000 fax 408.727.4748 www.sensoryinc.com sales@sensoryinc.com 16-bit microprocessor 1280-bytes ram 64/192/288-kbytes rom timer 1 timer 2 pllm 10-bit dac 16/32/64 i/o comparator sc-614 only sc-6 x block diagram sc-604 sc-605 sc-601 sc-614 rom (bytes) 64k 288k 192k 64k ram (bits) 10880 10880 10880 10880 i/o pins (packaged) 16 32 32 64 i/o pins (die) 16 32 32 64 pin count (package) 64 100 100 100 pin count (die) 36 53 53 85 built-in dac yes yes yes yes built-in comparator yes yes yes yes max speech duration (1.0 kbps internal rom) 6.5 min 37 min 24 min 6.5 min * sensory SC-6X family of processors * the sc-614 can be interfaced to external memory for longer h
