GENERAL D ESCRIP TIO N

T he ADSP-2185 is a single-chip microcomputer optimized for

digital signal processing (DSP) and other high speed numeric

processing applications.

SYSTEM INTERFACE

16-Bit Internal DMA Port for High Speed Access to

On-Chip Mem ory (Mode Selectable)

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.

4 MByte Byte Mem ory Interface for Storage of Data

Tables & Program Overlays

8-Bit DMA to Byte Mem ory for Transparent Program

and Data Mem ory Transfers (Mode Selectable)

I/ O Mem ory Interface w ith 2048 Locations Supports

Parallel Peripherals (Mode Selectable)

Program m able Mem ory Strobe & Separate I/ O Mem ory

Space Perm its “Glueless” System Design

(Mode Selectable)

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.

Program m able Wait State Generation

Tw o Double-Buffered Serial Ports w ith Com panding

Hardw are and Autom atic Data Buffering

Autom atic Booting of On-Chip Program Mem ory from

Byte-Wide External Mem ory, e.g., EPROM, or

Through Internal DMA Port

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.
