RSC-164
RSC-164 ARCHITECTURE
The RSC-164 is a highly integrated device that
combines:
The RSC-164 has an external memory interface, with 16-
bit addresses and a 8-bit data buses, for accessing
external memory. It also has an internal ROM that can be
enabled or disabled (partially or fully) by pin inputs
(signals -XMH, -XML).
Two bi-directional ports provide 16 general purpose I/O
pins to communicate with external devices. The RSC-164
has a high frequency (14.32 MHz) oscillator as well as a
low frequency (32,768 Hz) oscillator suitable for
timekeeping applications. The processor clock can be
selected from either source, with a selectable divider
value. The device performs speech recognition when
running at 14.32 MHz.
programmable wait states to allow the use of slower
external devices.
counters / timers, one derived from each oscillator.

From the Interactive Speech™ Line of Products
A microphone with an external preamp converts sound
into an audio signal that is fed to the RSC-164. The gain
of the external preamp may be controlled by the RSC-164
by using two of the I/O lines. The RSC-164 uses an ADC
(Analog-to-Digital Converter) to convert incoming
analog speech signal into digital data. The output audio
signal of the RSC-164 is derived from a DAC (Digital-to-
Analog Converter) or PWM (Pulse Width Modulator).
USING THE RSC-164
Creating applications using the RSC-164 requires the
development of electronic circuitry, software code, and
speech/music data files. Software code for the RSC-164
can be developed by Sensory or by external programmers
using the RSC Development Kit. For more information
about development tools and services, please contact
Sensory. A typical product will require about $0.80 -
$1.50 (in high volume) of additional components, in
addition to the RSC-164.
The following sample circuit provides an example of how
the RSC-164 might be used.
