SC-6X

SC-6X FAMILY SPEECH AND MUSIC PROCESSORS 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. POWERFUL TECHNOLOGY The SC-6x product family introduces a new world of speech synthesis opportunities. This family is built around 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 features 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. Your product’s quality will speak for itself. If your product needs music, Sensory offers several choices, including simultaneous speech with high quality polyphonic music. A RANGE OF CHOICES Not only can you choose the optimum combination of price and capacity, you can adopt any of these digital storage alternatives: On-chip mask programmable ROM, External memory (SC-614 only). TYPES OF SYNTHESIS Memory Required per Minute of Speech (KB) Data Rate Kbps CX synthesis is your solution for producing long durations of great speech and sound effects at the lowest possible system cost. MX offers data rates as low as 1K bits-persecond, yielding high quality speech with minimal development effort. 3.0~11.2 22.5~84.0 MX synthesis provides optimal speech and sound effects. Its highly sophisticated analysis can reproduce the subtle qualities 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 1.8 7.5~26.2 13.5 LPC is mathematically simpler than MX or CX, requiring less processing power but more editing. 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 Musical 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. Product Brief (80-0213-C) SC-6X FAMILY 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! 16-Bit Microprocessor 10-Bit DAC 1280-Bytes RAM TIMER 1 TIMER 2 PLLM 64/192/288-KBytes ROM COMPARATOR 16/32/64 I/O SC-614 only SC-6X BLOCK DIAGRAM SC-604 ROM (bytes) I/O Pins (packaged) I/O Pins (die) Pin Count (package) Pin Count (die) Built-In DAC Built-In Comparator 64K 16 16 64 36 Yes Yes RAM (bits) 10880 SC-605 288K 10880 32 32 100 53 Yes Yes 37 min SC-601 192K 10880 32 32 100 53 Yes Yes SC-614 64K 10880 64 64 100 85 Yes Yes Max Speech Duration 6.5 min (1.0 Kbps internal ROM) 24 min 6.5 min * Sensory SC-6x family of processors * The SC-614 can be interfaced to external memory for longer SC-691 h 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 microprocessors or microcontrollers and converts it to speech output. Since no SC-6x programming knowledge is needed, this is the simplest SC-6x family member to develop with.
