SC-614 data sheet 2 p/n 80-0210-c ? 2003 sensory inc. the data memory is internal static ram. the ram is configured in 640 17-bit words. both memories are designed to consume minimum power at a given sy stem clock and algorithm acquisition frequency. a flexible clock generation system enables the software to control the clock over a wide frequency range. the implementation uses a phase-locked loop (pll) circuit that drives the processor clock at a selectable frequency between the minimum and maximum achievable. selectable frequencies for the processor clock are spaced apart in 65.536 khz steps. the pll clock-reference is also selectable; either a resi stor-trimmed oscillator or a crystal-referenced oscillator may be used. internal and external clock sources are controlled separately to provide different levels of power management. the periphery consists of five 8-bit wide general-purpose i/o ports, one 8-bit wide dedicated input port, and one 16-bit wide dedicated output port. the bidirectional i/o ca n be configured under software control as either high- impedance inputs or as totem-pole outputs. they are c ontrolled via addressable i/o registers. the input-only port has a programmable pullup option (70k minimum resistance) and a dedicated service interrupt. these features make the input port especia lly useful as a key-scan interface. a simple one-bit comparator is also included in the pe riphery. the comparator is enabled by a control register, and its pin access is shared with two pins in one of the general-purpose i/o ports. rounding out the SC-614 periphery is a built-in pulse-density-modulated dac (dig ital-to-analog converter) wi th direct speaker-drive capability. the functional bl ock diagram gives an overview of the SC-614 functionality. functional block diagram

product line the interactive speech line of ics and software was developed to ?bring life to products? thr ough advanced speech recognition a nd audio technology. the interactive speech product line was desig ned for consumer telephony products and cost -sensitive consumer electronic applica tions such as home electronics, personal se curity, and personal communication. the product line includes award-winning rsc se ries general-purpose microcontrollers and t ools, sc series of speech microcontrol lers, plus a line of easy-to-implement chips that can be pin-configured or controlled by an external host microcontroller. sensory?s softw are technologies run on a variety of microcontrollers and dsps. rsc microcontrollers and tools the rsc product line contains low-cost 8-bit speech- optimized microcontrollers des igned for use in consumer electronics. all members of the rsc fa mily are fully integrated and include a/d, pre-amplifier, d/a, rom, and ram circuitry. the rsc family can perform a full range of speech/audio functions includi ng speech recognition, speaker verification, speech and music synthesis, and voice record/playback. the family is supported by a complete suite of evaluation tools and development kits. sc microcontrollers and tools the sc-6x product line feature the highest qua lity speech synthesis ics at the lowest data rate in the industry. the line inclu des a 12.32 mips processor for high-quality low data-rate speech compression and midi music synthesis, with plenty of power left over for o ther processor and control functions. members of the sc-6x line can store as much as 37 mi nutes of speech on chip and include as muc h as 64 i/o pins for external interfacing. integrating this broad range of features onto a single chip enables developers to create products with high quality, long duration speech at very competitive price points. application specific standard products (assps) voice direct? ii provides inexpensive speaker-depen dent speech recognition and speech synt hesis. this easy-to-use, pin- configurable chip requires no custom programming and can recognize up to 15 words in 4 pin-prog rammable modes. ideal for speake r- dependent command and control of household consumer products, voice direct ? ii is part of a complete product line that includes the ic, module, and voice direct ? ii speech recognition kit. voice extreme? simplifies the creation of fully custom speech- enabled products by offering developers the capability of programming the chip in a high-level c-like language. pr ogram code, speech data, and even record and playback information can be stored on a single off-chip flash memo ry. based on sensory's rsc-364 speech processor, voice extreme includes a highly efficient on-chip code interpreter, and is supported by a comprehensive suite of low-cost development tools. software and technology voice activation? micro footprint software provides advanced speec h technology on a variety of microcontroller and dsp platforms. a flexible design with a broa d range of technologies allows manufacturers to easily integrate speech functionality into consumer electronic products. fluent speech? small footprint software recognizes up to 50,000 words; offers animated speech with the ability to automate enunciation and articulation; performs text-to-speech synthesis in either male or female voices ; provides noise and echo cancel lation, performs wordspotting for natural language usage; offers tel ephone barge-in; and provides c ontinuous digit recognition. important notices reasonable efforts have been made to verify the accuracy of info rmation contained herein, however no guarantee can be made of accuracy or applicability. sensory reserv es the right to change any specification or description contained herein. sensory rese rves the right to make changes to or to discontinue any product or service identified in this publication at any time without notice in order to improve design and supply the best possible product. sensory does not assume responsibilit y for use of any circuitry other than circuitry entirely embodied in a sensory product. info rmation contained herein is provided gratui tously and without liability to any user . reasonable efforts have been made to verify the accuracy of this in formation but no guarantee whatsoev er is given as to the acc uracy or as to its applicability to particular uses. applications de scribed in this data sheet are for illustrative purposes only, an d sensory makes no warranties or representations that the rsc/sc series of pr oducts will be suitable for such applications. in every instance, it must be the responsibility of the user to determine the suitability of the products for each application. sensory products are not auth orized for use as critical components in life support devices or systems. sensory conveys no license or title, either expressed or implied, un der any patent, copyright, or mask work right to the rsc series of products, and sensory makes balanc e between recognition and synthesi s no warranties or representations that the rsc series of products are free from patent, copyright, or mask work right infringement, unless otherwise specified. nothing contained herei n shall be construed as a recommendation to use any product in violation of existin g patents or other rights of third parties. the sale of any sens ory product is subject to all s ensory terms and conditions of sal es and sales policies.
