ADSP-2100 CORE
Fabricated in a high speed, submicron, double-layer metal
CMOS process, the highest-performance ADSP-216x proces-
sors operate at 25 MHz with a 40 ns instruction cycle time.
Every instruction can execute in a single cycle. Fabrication in
CMOS results in low power dissipation.
The ADSP-2100 Family鈥檚 flexible architecture and compre-
hensive instruction set support a high degree of parallelism.
In one cycle the ADSP-216x can perform all of the following
operations:
GENERAL DESCRIPTION
The ADSP-216x Family processors are single-chip micro-
computers optimized for digital signal processing (DSP)
and other high speed numeric processing applications. The
ADSP-216x processors are all built upon a common core with
ADSP-2100. Each processor combines the core DSP architec-
ture鈥攃omputation units, data address generators and program
sequencer鈥攚ith features such as on-chip program ROM and
data memory RAM, a programmable timer and two serial ports.
The ADSP-2165/ADSP-2166 also adds program memory and
power-down mode.
This data sheet describes the following ADSP-216x Family
processors:
ADSP-2161/ADSP-2162/
ADSP-2163/ADSP-2164
ADSP-2165/ADSP-2166
Custom ROM-programmed DSPs:
ROM-programmed ADSP-216x
processors with power-down and
larger on-chip memories (12K Pro-
gram Memory ROM, 1K Program
Memory RAM, 4K Data Memory
RAM)

Table I shows the features of each ADSP-216x processor.
The ADSP-216x series are memory-variant versions of the
ADSP-2101 and ADSP-2103 that contain factory-programmed
on-chip ROM program memory. These devices offer different
amounts of on-chip memory for program and data storage.
Table I shows the features available in the ADSP-216x series of
custom ROM-coded processors.
The ADSP-216x products eliminate the need for an external
boot EPROM in your system, and can also eliminate the need
for any external program memory by fitting the entire applica-
tion program in on-chip ROM. These devices thus provide an
excellent option for volume applications where board space and
system cost constraints are of critical concern.
