DATA SHEET
RSC-300/364 ARCHITECTURE
The RSC-300/364 is a highly integrated device that
combines:
The RSC-300/364 has an external memory interface,
with 16-bit addresses and 8-bit data buses, for accessing
external memory. It also has an internal ROM (RSC-364
only) 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-
300/364 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. The RSC-300/364 also supports
programmable wait states to allow the use of slower

external devices.
counters / timers, one derived from each oscillator.
An external microphone passes an audio signal to the
preamplifier and ADC (Analog-to-Digital Converter) to
convert the incoming speech signal into digital data. The
output audio signal of the RSC-300/364 is derived from a
DAC (Digital-to-Analog Converter) or PWM (Pulse
Width Modulator).
USING THE RSC-300/364
Creating applications using the RSC-300/364 requires
the development of electronic circuitry, software code,
and speech/music data files. Software code for the RSC-
300/364 can be developed by Sensory or by external
programmers using the RSC-300/364 Development Kit.
For more information about development tools and
services, please contact Sensory. A typical product will
require about $0.30 - $1.00 (in high volume) of
additional components, in addition to the RSC-300/364.
The following sample circuit provides an example of how
the RSC-300/364 might be used in a consumer electronic
product.
