ADSP-218xN Series
GENERAL DESCRIPTION
This takes place while the processor continues to:
鈥?Receive and transmit data through the two serial ports
鈥?Receive and/or transmit data through the
internal DMA port
鈥?Receive and/or transmit data through the byte DMA port
鈥?Decrement timer
DEVELOPMENT SYSTEM
The ADSP-218xN series consists of six single chip micro-
computers optimized for digital signal processing applica-
tions. The high-level block diagram for the ADSP-218xN
series members appears on the previous page. All series
members are pin-compatible and are differentiated solely by
the amount of on-chip SRAM. This feature, combined with
ADSP-21xx code compatibility, provides a great deal of
flexibility in the design decision. Specific family members
are shown in
Table 1.

Analog Devices鈥?wide range of software and hardware
development tools supports the ADSP-218xN series. The
DSP tools include an integrated development environment,
an evaluation kit, and a serial port emulator.
VisualDSP++鈩?is an integrated development environment,
allowing for fast and easy development, debug, and deploy-
ment. The VisualDSP++ project management environment
lets programmers develop and debug an application. This
environment includes an easy-to-use assembler that is based
on an algebraic syntax; an archiver (librarian/library build-
er); a linker; a PROM-splitter utility; a cycle-accurate,
instruction-level simulator; a C compiler; and a C run-time
library that
includes DSP and mathematical functions.
Debugging both C and assembly programs with the
VisualDSP++ debugger, programmers can:
鈥?View mixed C and assembly code (interleaved source and
object information)
鈥?Insert break points
鈥?Set conditional breakpoints on registers, memory, and
stacks
鈥?Trace instruction execution
鈥?Fill and dump memory
鈥?Source level debugging
The VisualDSP++ IDE lets programmers define and
manage DSP software development. The dialog boxes and
property pages let programmers configure and manage all
of the ADSP-218xN development tools, including the
syntax highlighting in the VisualDSP++ editor. This capa-
bility controls how the development tools process inputs and
generate outputs.
The ADSP-2189M EZ-KIT Lite鈩?provides developers
with a cost-effective method for initial evaluation of the
powerful ADSP-218xN DSP family architecture. The
ADSP-2189M EZ-KIT Lite includes a stand-alone ADSP-
2189M DSP board supported by an evaluation suite of
VisualDSP++. With this EZ-KIT Lite, users can learn
about DSP hardware and software development and evalu-
ate potential applications of the ADSP-218xN series. The
ADSP-2189M EZ-KIT Lite provides an evaluation suite of
the VisualDSP++ development environment with the
C compiler, assembler, and linker. The size of the DSP
erxecutable that can be built using the EZ-KIT Lite tools is
limited to 8K words.

ADSP-218xN series members combine the ADSP-2100
family base architecture (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 capa-
bilities, and on-chip program and data memory.
ADSP-218xN series members integrate up to 256K bytes
of on-chip memory configured as up to 48K words (24-bit)
of program RAM, and up to 56K words (16-bit) of data
RAM. Power-down circuitry is also provided to meet the
low power needs of battery-operated portable equipment.
The ADSP-218xN is available in a 100-lead LQFP package
and 144-Ball Mini-BGA.
Fabricated in a high-speed, low-power, 0.18 碌m CMOS
process, ADSP-218xN series members operate with a
12.5 ns instruction cycle time. Every instruction can
execute in a single processor cycle.
The ADSP-218xN鈥檚 flexible architecture and comprehen-
sive instruction set allow the processor to perform multiple
operations in parallel. In one processor cycle, ADSP-218xN
series members can:
鈥?Generate the next program address
鈥?Fetch the next instruction
鈥?Perform one or two data moves
鈥?Update one or two data address pointers
鈥?Perform a computational operation
