Description
The SC-614 is a low-cost, mixed-signal processor that combines a speech synthesizer, general-purpose I/O, onboard ROM, and direct speaker-drive in a single package. The computational unit utilizes a powerful new DSP which gives the SC-614 unprecedented speed and computational flexibility compared with previous devices of its type. The SC-614 supports a variety of speech and audio coding algorithms, providing a range of options with respect to speech duration and sound quality.

64 I/O
The device consists of a micro-DSP core, embedded program, and data memory, and a self-contained clock generation system. General-purpose periphery is comprised of 64 bits of partially configurable I/O. The core processor is a general-purpose 16-bit microcontroller with DSP capability. The basic core block includes computational unit (CU), data address unit, program address unit, two timers, eight level interrupt processor, and several system and control registers. The core processor gives the SC-614 break-point capability in emulation. The processor is Harvard type for efficient DSP algorithm execution. It requires separate program and data memory blocks to permit simultaneous access. It is configured in 32K 17-bit words. The total ROM space is divided into two areas: 1. The lower 2K words are reserved by Sensory for the purposes of a built-in self-test 2. The upper 30K is for user program/data (c) 2003 Sensory Inc. P/N 80-0210-C 1

Data sheet
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 system 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 resistor-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 can be configured under software control as either highimpedance inputs or as totem-pole outputs. They are controlled 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 especially useful as a key-scan interface. A simple one-bit comparator is also included in the periphery. 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 (digital-to-analog converter) with direct speaker-drive capability. The functional block diagram gives an overview of the SC-614 functionality.

The VSS and VDD connections service the DAC circuitry. Their pins tend to sustain a higher current draw. A dedicated decoupling capacitor across these pins is therefore required.

The Interactive SpeechTM Product Line
The Interactive Speech line of ICs and software was developed to "bring life to products" through advanced speech recognition and audio technology. The Interactive Speech Product Line was designed for consumer telephony products and cost-sensitive consumer electronic applications such as home electronics, personal security, and personal communication. The product line includes award-winning RSC series general-purpose microcontrollers and tools, SC series of speech microcontrollers, plus a line of easy-to-implement chips that can be pin-configured or controlled by an external host microcontroller. Sensory's software 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 designed for use in consumer electronics. All members of the RSC family 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 including 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 quality speech synthesis ICs at the lowest data rate in the industry. The line includes a 12.32 MIPS processor for high-quality low data-rate speech compression and MIDI music synthesis, with plenty of power left over for other processor and control functions. Members of the SC-6x line can store as much as 37 minutes of speech on chip and include as much 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 DirectTM II provides inexpensive speaker-dependent speech recognition and speech synthesis. This easy-to-use, pinconfigurable chip requires no custom programming and can recognize up to 15 words in 4 pin-programmable modes. Ideal for speakerdependent command and control of household consumer products, Voice DirectTM II is part of a complete product line that includes the IC, module, and Voice DirectTM II Speech Recognition Kit. Voice ExtremeTM 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. Program code, speech data, and even record and playback information can be stored on a single off-chip Flash memory. 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 ActivationTM micro footprint software provides advanced speech technology on a variety of microcontroller and DSP platforms. A flexible design with a broad range of technologies allows manufacturers to easily integrate speech functionality into consumer electronic products. Fluent SpeechTM 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 cancellation, performs Wordspotting for natural language usage; offers telephone barge-in; and provides continuous digit recognition.
