Description
SC-614 Block Diagram
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.

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

SC-614
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 Interactive Speech™ 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 Direct™ 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 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. 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 Activation™ 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 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 cancellation,
performs Wordspotting for natural language usage; offers telephone barge-in; and provides continuous digit recognition.
