GENERAL DESCRIPTION
The ADSP-2186 is a single-chip microcomputer optimized for
digital signal processing (DSP) and other high speed numeric
processing applications.
The ADSP-2186 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.
The ADSP-2186 integrates 40K bytes of on-chip memory con-
figured as 8K words (24-bit) of program RAM and 8K words
(16-bit) of data RAM. Power-down circuitry is also provided to
meet the low power needs of battery operated portable equip-
ment. The ADSP-2186 is available in 100-lead LQFP and
144-Ball Mini-BGA packages.
In addition, the ADSP-2186 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.
