DATA SHEET
Sample Application Circuit
RSC-164 INSTRUCTION SET
The instruction set for the RSC-164 has 52 instructions
comprising 8 move, 7 rotate, 11 branch, 11 register
arithmetic, 9 immediate arithmetic, and 6 miscellaneous
instructions. All instructions are 3 bytes or fewer, and no
instruction requires more than 8 clock cycles to execute.
GENERAL PURPOSE I/O
The RSC-164 has 16 general purpose I/O pins (P0.0-
P0.7, P1.0-P1.7). Each pin can be programmed as an
input with weak pull-up (~200k
input with strong pull-up (~10k
input without pull-up, or as an output. This is
accomplished by having 32 bits of configuration registers
for the I/O pins (Port Control Register A and Port
Control Register B for ports 0 and 1).
EXTERNAL MEMORY
The RSC-164 includes an external memory interface that
allows connection with memory devices for speaker-
dependent speech recognition, audio record/playback,
PREAMP GND and AGND to be connected at
the power supply near the RSC-164

Transistor should have low (.1V) Vce(sat), @
a forced beta of 100 @ 100mA Ic. V(br)ebo
should be above 5V.
NEC's 9012H is an acceptable example.

extended durations of speech and music synthesis, and
enhanced product functionality.
Separate data and address buses allow use of standard
EPROMs, ROMs, SRAMs, and flash memory with little
or no additional decoding. Provision of separate read and
write signals for each external memory space further
simplifies interfacing.
lines (D[7:0]) and 16 address lines (A[15:0]), along with
associated control signals for interfacing to external
memory.
Using flash memory and EEPROM will require custom
code development. The RSC-164 can connect serially
through two I/O lines to a serial EEPROM for
applications with low data storage requirements.
OSCILLATORS
Two independent oscillators in the RSC-164 provide a
high-frequency clock and a 32kHz time-keeping clock.
The oscillator characteristics are as follows:
