Description
Features
Sensory’s RSC-4x Rapid Prototyping Module
(RSC-4x RPM) simplifies prototyping of products
featuring speech technologies by integrating key
components into a convenient 40-pin DIP footprint
module. With the RSC-4x RPM’s 32Mbit Flash
FluentChip™ Capabilities
Noise-robust Speaker Independent (SI) and
Speaker Dependent (SD) recognition
Many language models now available for
international use
High quality, 2.4-7.8 kbps speech synthesis &
sound effects with Sensory "SX" synthesis
technology
Speech with “SXL” compression
Speaker Verification Word Spot (SVWS) Noise robust voice biometric security
8 voice MIDI-compatible music synthesis
Audio Wakeup from sleep
Touch Tone (DTMF) output
Record and Playback (RP)
memory, Sensory’s entire FluentChip™ library can
be utilized including Record and Playback, along
with lots of extended speech. The RPM is a
prototyping tool designed for developers who will be
creating product system designs that feature RSC-4x
processor chips.
Using the Module Programming Board (MPB),
developers can download application programs into
the RSC-4x RPM. The module can then be removed
from the MPB and plugged directly into the prototype
for real world testing. In-circuit reprogramming is
also supported.

Major Components
U3 RSC-4128 IC
An RSC-4128 Integrated Circuit is the central speech processor.
Y1 Crystal
A 3.57 MHz crystal drives a 14.3MHz phase lock loop (PLL) in the RSC-4128 to create the system clock. Timer
1 is used for all speech recognition functions, and should only be used by the application programmer who is not
using speech recognition. Timer 3 is reserved for the application programmer.
Y2 Crystal
A 32.768 KHz crystal establishes the frequency of Timer 2 on the RSC-4128 IC. Timer 2 is useful for
timekeeping applications since it is not interrupted, unlike Timer 1.
R4 Microphone Source (gain) Resistor
A 1.8K on-board through-hole microphone source resistor is calibrated for use with a microphone with -44dB
sensitivity with 2.2K. This satisfies the -46dB system gain.
U2 4M Bit Flash Memory
This 4Mb Flash memory stores the application binary code.
U4 32M Bit Serial Flash Memory
This 32M bit Serial Flash is designed to store speech templates, Record and Playback data, and application
data.

Data Sheet
RSC-4x RPM
General Purpose I/O
Bidirectional: The RSC-4x RPM has 24 general purpose I/O pins. Each line can be programmed as an input with
a weak pull-up resistor, input with a strong pull-up resistor, input without pull-ups, or as an output. For more
details, refer to the RSC-4128 Datasheet (80-0206).
Microphone Ports
Input: The RSC-4x RPM is designed so that you can use the on-board 1.2K microphone source resistor or
external custom microphone source resistor. Use the on-board microphone resistor if the microphone sensitivity
provides -49dB system gain with 1.2K. Use the external microphone source resistor otherwise. For more
information on microphones, refer to Design Note - Selecting a Microphone (80-0259).
NOTE: Sleep Current is 100uA (typ.) with a microphone.
Speaker Output (PWM0, PWM1)
Output: PWM ports can be directly connected to the speaker.
DAC Output
Output: An optional DAC output for the speaker is provided. To use DAC output, you need to provide the
external audio amplifier.
RSC-4x RPM Schematic
Refer to: RSC-4x RPM Schematic (70-0068).
Developing RSC-4x RPM Applications
What you can develop with the RSC-4x RPM:
Speaker Independent Recognition
Speaker Dependent Recognition
Speaker Verification
Record and Playback
Speech with SXL compression
Sample Programs
Sample programs in the FluentChip™ Technology Library are a great place to start. Please refer to the Module
Programmer Board Manual (80-0294) for the complete list of supported samples.

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 technologies. It is designed for cost-sensitive consumer-electronic applications such as home
electronics, home automation, toys, and personal communication. The product line includes the award-winning RSC-4x
general-purpose microcontrollers and tools, the VR Stamp™ 40 pin DIP module and tools, the SC series of speech and
music synthesis microcontrollers. Our suite of software development kits are designed to run on non-Sensory processors
and DSP’s, and support most popular operating systems.
RSC Microcontrollers and Tools
The RSC product family 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 recording/playback. The family is supported by a complete suite of evaluation and development
toolkits.
Speech Recognition Modules and Tools
The VR Stamp™ is a complete speech recognition module based on the RSC-4x and is ideal for fast design and easy
production. A low-noise audio channel and standardized 40-pin DIP footprint allow rapid prototyping, less debugging, and
shorter time to market. The VR Stamp Toolkit includes everything needed to get started today, including VR Stamps, Module
Programming Board, sample applications, and a complete set of development tools featuring the Phyton IDE and limited-life
C compiler, QuickSynthesis™ 4 and Quick T2SI-Lite™ speech tools.
SC Microcontrollers and Tools
The SC-6x product family features 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 processing and control functions. Members of the SC-6x line can store as much as 37 minutes of
speech on-chip and include as many as 64 I/O pins for external interfacing. Integrating this broad range of features into a
single chip enables developers to create products with high quality, long duration speech at very competitive price points.
FluentSoft™ Technology
FluentSoft™ Recognizer is the engine powering the FluentSoft™ SDK. It provides a noise-robust, large-vocabulary, speakerindependent solution with continuous digit recognition and word-spotting capabilities. This small-footprint software
recognizes up to 5,000 words; runs on non-Sensory processors including Intel XScale, TI OMAP, and ARM9 platforms; and
supports operating systems such as MS Windows, Linux, and Symbian.
3Dmsg™ Technology
3Dmsg’s (www.3Dmsg.com) Animated Speech technology offers animated avatars with advanced speech recognition and
synthesis capabilities for use in smartphones, language trainers, and kiosk applications. Facial expressions can be
configured to show emotions and lip synchronization can be automatically driven from voice or text data.
