T his data sheet represents production grade specifications for
the ADSP-2185 (5 V).
GE NE RAL DE SCRIPT ION
T he ADSP-2185 is a single-chip microcomputer optimized for
digital signal processing (DSP) and other high speed numeric
processing applications.
T he ADSP-2185 combines the ADSP-2100 family base archi-
tecture (three computational units, data address generators and
a program sequencer) with two serial ports, a 16-bit internal
DMA port, a byte DMA port, a programmable timer, Flag I/O,
extensive interrupt capabilities and on-chip program and data
memory.
T he ADSP-2185 integrates 80K bytes of on-chip memory con-
figured as 16K words (24-bit) of program RAM and 16K words
(16-bit) of data RAM. Power-down circuitry is also provided to
meet the low power needs of battery operated portable equip-
ment. T he ADSP-2185 is available in 100-pin T QFP package.
In addition, the ADSP-2185 supports new instructions, which
include bit manipulations—bit set, bit clear, bit toggle, bit test—
new ALU constants, new multiplication instruction (x squared),
biased rounding, result free ALU operations, I/O memory trans-
fers and global interrupt masking, for increased flexibility.
