GENERAL DESCRIPTION

The ADSP-2186 is a single-chip microcomputer optimized for

digital signal processing (DSP) and other high speed numeric

processing applications.

144-Ball Mini-BGA

SYSTEM INTERFACE

16-Bit Internal DMA Port for High Speed Access to

On-Chip Memory (Mode Selectable)

4 MByte Byte Memory Interface for Storage of Data

Tables and Program Overlays

8-Bit DMA to Byte Memory for Transparent Program

and Data Memory Transfers (Mode Selectable)

I/O Memory Interface with 2048 Locations Supports

Parallel Peripherals (Mode Selectable)

Programmable Memory Strobe and Separate I/O Memory

Space Permits “Glueless” System Design

(Mode Selectable)

Programmable Wait State Generation

Two Double-Buffered Serial Ports with Companding

Hardware and Automatic Data Buffering

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.
