(ADSP-2111 only)
The ADSP-2101, ADSP-2105, and ADSP-2115 comprise the
basic set of processors of the family. Each of these three devices
contains program and data memory RAM, an interval timer,
and one or two serial ports. The ADSP-2103 is a 3.3 volt
power supply version of the ADSP-2101; it is identical to the
ADSP-2101 in all other characteristics. Table I shows the
features of each ADSP-21xx processor.
The ADSP-2111 adds a 16-bit host interface port (HIP) to the
basic set of ADSP-21xx integrated features. The host port
provides a simple interface to host microprocessors or
microcontrollers such as the 8031, 68000, or ISA bus.

ADSP-21xx
The ADSP-216x series are memory-variant versions of the
ADSP-2101 and ADSP-2103 that contain factory-programmed
on-chip ROM program memory. These devices offer different
amounts of on-chip memory for program and data storage.
Table II shows the features available in the ADSP-216x series of
custom ROM-coded processors.
The ADSP-216x products eliminate the need for an external
boot EPROM in your system, and can also eliminate the need
for any external program memory by fitting the entire application program in on-chip ROM. These devices thus provide an
excellent option for volume applications where board space and
system cost constraints are of critical concern.
Development Tools
The ADSP-21xx processors are supported by a complete set of
tools for system development. The ADSP-2100 Family Development Software includes C and assembly language tools that
allow programmers to write code for any of the ADSP-21xx
processors. The ANSI C compiler generates ADSP-21xx
assembly source code, while the runtime C library provides
ANSI-standard and custom DSP library routines. The ADSP21xx assembler produces object code modules which the linker
combines into an executable file. The processor simulators
provide an interactive instruction-level simulation with a
reconfigurable, windowed user interface. A PROM splitter
utility generates PROM programmer compatible files.
EZ-ICE® in-circuit emulators allow debugging of ADSP-21xx
systems by providing a full range of emulation functions such as
modification of memory and register values and execution
breakpoints. EZ-LAB® demonstration boards are complete DSP
systems that execute EPROM-based programs.
The EZ-Kit Lite is a very low-cost evaluation/development
platform that contains both the hardware and software needed
to evaluate the ADSP-21xx architecture.
Additional details and ordering information is available in the
ADSP-2100 Family Software & Hardware Development Tools data
sheet (ADDS-21xx-TOOLS). This data sheet can be requested
from any Analog Devices sales office or distributor.
Additional Information
This data sheet provides a general overview of ADSP-21xx
processor functionality. For detailed design information on the
architecture and instruction set, refer to the ADSP-2100 Family
User’s Manual, available from Analog Devices.
ARCHITECTURE OVERVIEW
Figure 1 shows a block diagram of the ADSP-21xx architecture.
The processors contain three independent computational units:
the ALU, the multiplier/accumulator (MAC), and the shifter.
The computational units process 16-bit data directly and have
provisions to support multiprecision computations. The ALU
performs a standard set of arithmetic and logic operations;
division primitives are also supported. The MAC performs
single-cycle multiply, multiply/add, and multiply/subtract
operations. The shifter performs logical and arithmetic shifts,
normalization, denormalization, and derive exponent operations.
The shifter can be used to efficiently implement numeric format
control including multiword floating-point representations.
The internal result (R) bus directly connects the computational
units so that the output of any unit may be used as the input of
any unit on the next cycle.
A powerful program sequencer and two dedicated data address
generators ensure efficient use of these computational units.
The sequencer supports conditional jumps, subroutine calls,
and returns in a single cycle. With internal loop counters and
loop stacks, the ADSP-21xx executes looped code with zero
overhead—no explicit jump instructions are required to
maintain the loop.
Two data address generators (DAGs) provide addresses for
simultaneous dual operand fetches (from data memory and
program memory). Each DAG maintains and updates four
address pointers. Whenever the pointer is used to access data
(indirect addressing), it is post-modified by the value of one of
four modify registers. A length value may be associated with
each pointer to implement automatic modulo addressing for
circular buffers. The circular buffering feature is also used by
the serial ports for automatic data transfers to (and from) onchip memory.
Efficient data transfer is achieved with the use of five internal
buses:
•
•
•
•
•
Program Memory Address (PMA) Bus
Program Memory Data (PMD) Bus
Data Memory Address (DMA) Bus
Data Memory Data (DMD) Bus
Result (R) Bus
The two address buses (PMA, DMA) share a single external
address bus, allowing memory to be expanded off-chip, and the
two data buses (PMD, DMD) share a single external data bus.
The BMS, DMS, and PMS signals indicate which memory
space is using the external buses.
Program memory can store both instructions and data, permitting the ADSP-21xx to fetch two operands in a single cycle, one
from program memory and one from data memory. The
processor can fetch an operand from on-chip program memory
and the next instruction in the same cycle.
The memory interface supports slow memories and memorymapped peripherals with programmable wait state generation.
External devices can gain control of the processor’s buses with
the use of the bus request/grant signals (BR, BG).

Figure 1. ADSP-21xx Block Diagram
One bus grant execution mode (GO Mode) allows the ADSP21xx to continue running from internal memory. A second
execution mode requires the processor to halt while buses are
granted.
Each ADSP-21xx processor can respond to several different
interrupts. There can be up to three external interrupts,
configured as edge- or level-sensitive. Internal interrupts can be
generated by the timer, serial ports, and, on the ADSP-2111,
the host interface port. There is also a master RESET signal.
Booting circuitry provides for loading on-chip program memory
automatically from byte-wide external memory. After reset,
three wait states are automatically generated. This allows, for
example, a 60 ns ADSP-2101 to use a 200 ns EPROM as
external boot memory. Multiple programs can be selected and
loaded from the EPROM with no additional hardware.
The data receive and transmit pins on SPORT1 (Serial Port 1)
can be alternatively configured as a general-purpose input flag
and output flag. You can use these pins for event signalling to
and from an external device. The ADSP-2111 has three
additional flag outputs whose states are controlled through
software.
A programmable interval timer can generate periodic interrupts.
A 16-bit count register (TCOUNT) is decremented every n
cycles, where n–1 is a scaling value stored in an 8-bit register
(TSCALE). When the value of the count register reaches zero,
an interrupt is generated and the count register is reloaded from
a 16-bit period register (TPERIOD).
REV. B
Serial Ports
The ADSP-21xx processors include two synchronous serial
ports (“SPORTs”) for serial communications and multiprocessor communication. All of the ADSP-21xx processors have two
serial ports (SPORT0, SPORT1) except for the ADSP-2105,
which has only SPORT1.
The serial ports provide a complete synchronous serial interface
with optional companding in hardware. A wide variety of
framed or frameless data transmit and receive modes of operation are available. Each SPORT can generate an internal
programmable serial clock or accept an external serial clock.
Each serial port has a 5-pin interface consisting of the following
signals:
Signal Name
Function
SCLK
RFS
TFS
DR
DT
Serial Clock (I/O)
Receive Frame Synchronization (I/O)
Transmit Frame Synchronization (I/O)
Serial Data Receive
Serial Data Transmit
The ADSP-21xx serial ports offer the following capabilities:
Bidirectional—Each SPORT has a separate, double-buffered
transmit and receive function.
Flexible Clocking—Each SPORT can use an external serial
clock or generate its own clock internally.
–5–
ADSP-21xx
Flexible Framing—The SPORTs have independent framing
for the transmit and receive functions; each function can run in
a frameless mode or with frame synchronization signals internally generated or externally generated; frame sync signals may
be active high or inverted, with either of two pulse widths and
timings.
Different Word Lengths—Each SPORT supports serial data
word lengths from 3 to 16 bits.
Companding in Hardware—Each SPORT provides optional
A-law and µ-law companding according to CCITT recommendation G.711.
Flexible Interrupt Scheme—Receive and transmit functions
can generate a unique interrupt upon completion of a data word
transfer.
Autobuffering with Single-Cycle Overhead—Each SPORT
can automatically receive or transmit the contents of an entire
circular data buffer with only one overhead cycle per data word;
an interrupt is generated after the transfer of the entire buffer is
completed.
Multichannel Capability (SPORT0 Only)—SPORT0
provides a multichannel interface to selectively receive or
transmit a 24-word or 32-word, time-division multiplexed serial
bit stream; this feature is especially useful for T1 or CEPT
interfaces, or as a network communication scheme for multiple
processors. (Note that the ADSP-2105 includes only SPORT1,
not SPORT0, and thus does not offer multichannel operation.)
Alternate Configuration—SPORT1 can be alternatively
configured as two external interrupt inputs (IRQ0, IRQ1) and
the Flag In and Flag Out signals (FI, FO).
Host Interface Port (ADSP-2111)
The ADSP-2111 includes a Host Interface Port (HIP), a
parallel I/O port that allows easy connection to a host processor.
Through the HIP, the ADSP-2111 can be accessed by the host
processor as a memory-mapped peripheral. The host interface
port can be thought of as an area of dual-ported memory, or
mailbox registers, that allows communication between the
computational core of the ADSP-2111 and the host computer.
The host interface port is completely asynchronous. The host
processor can write data into the HIP while the ADSP-2111 is
operating at full speed.
Three pins configure the HIP for operation with different types
of host processors. The HSIZE pin configures HIP for 8- or 16bit communication with the host processor. HMD0 configures
the bus strobes, selecting either separate read and write strobes
or a single read/write select and a host data strobe. HMD1
selects either separate address (3-bit) and data (16-bit) buses or
a multiplexed 16-bit address/data bus with address latch enable.
Tying these pins to appropriate values configures the ADSP2111 for straight-wire interface to a variety of industry-standard
microprocessors and microcomputers.
The HIP contains six data registers (HDR5-0) and two status
registers (HSR7-6) with an associated HMASK register for
masking interrupts from individual HIP data registers. The HIP
data registers are memory-mapped in the internal data memory
of the ADSP-2111. The two status registers provide status
information to both the ADSP-2111 and the host processor.
HSR7 contains a software reset bit which can be set by both the
ADSP-2111 and the host.
HIP transfers can be managed using either interrupts or polling.
The HIP generates an interrupt whenever an HDR register
receives data from a host processor write. It also generates an
interrupt when the host processor has performed a successful
read of any HDR. The read/write status of the HDRs is also
stored in the HSR registers.
The HMASK register bits can be used to mask the generation of
read or write interrupts from individual HDR registers. Bits in
the IMASK register enable and disable all HIP read interrupts
or all HIP write interrupts. So, for example, a write to HDR4
will cause an interrupt only if both the HDR4 Write bit in
HMASK and the HIP Write interrupt enable bit in IMASK are
set.
The HIP provides a second method of booting the ADSP-2111
in which the host processor loads instructions into the HIP. The
ADSP-2111 automatically transfers the data, in this case
opcodes, to internal program memory. The BMODE pin
determines whether the ADSP-2111 boots from the host
processor through the HIP or from external EPROM over the
data bus.
Interrupts
The ADSP-21xx’s interrupt controller lets the processor
respond to interrupts with a minimum of overhead. Up to three
external interrupt input pins, IRQ0, IRQ1, and IRQ2, are
provided. IRQ2 is always available as a dedicated pin; IRQ1 and
IRQ0 may be alternately configured as part of Serial Port 1. The
ADSP-21xx also supports internal interrupts from the timer, the
serial ports, and the host interface port (on the ADSP-2111).
The interrupts are internally prioritized and individually
maskable (except for RESET which is non-maskable). The
IRQx input pins can be programmed for either level- or edgesensitivity. The interrupt priorities for each ADSP-21xx
processor are shown in Table III.
The ADSP-21xx uses a vectored interrupt scheme: when an
interrupt is acknowledged, the processor shifts program control
to the interrupt vector address corresponding to the interrupt
received. Interrupts can be optionally nested so that a higher
priority interrupt can preempt the currently executing interrupt
service routine. Each interrupt vector location is four instructions in length so that simple service routines can be coded
entirely in this space. Longer service routines require an
additional JUMP or CALL instruction.
Individual interrupt requests are logically ANDed with the bits
in the IMASK register; the highest-priority unmasked interrupt
is then selected.
The interrupt control register, ICNTL, allows the external
interrupts to be set as either edge- or level-sensitive. Depending
on bit 4 in ICNTL, interrupt service routines can either be
nested (with higher priority interrupts taking precedence) or be
processed sequentially (with only one interrupt service active at
a time).
–6–
REV. B
ADSP-21xx
The interrupt force and clear register, IFC, is a write-only
register that contains a force bit and a clear bit for each interrupt (except for level-sensitive interrupts and the ADSP-2111
HIP interrupts—these cannot be forced or cleared in software).
When responding to an interrupt, the ASTAT, MSTAT, and
IMASK status registers are pushed onto the status stack and
the PC counter is loaded with the appropriate vector address.
The status stack is seven levels deep (nine levels deep on the
ADSP-2111) to allow interrupt nesting. The stack is automatically popped when a return from the interrupt instruction is
executed.

SYSTEM INTERFACE
Figure 3 shows a typical system for the ADSP-2101, ADSP2115, or ADSP-2103, with two serial I/O devices, a boot
EPROM, and optional external program and data memory. A
total of 15K words of data memory and 16K words of program
memory is addressable for the ADSP-2101 and ADSP-2103. A
total of 14.5K words of data memory and 15K words of
program memory is addressable for the ADSP-2115.
Figure 4 shows a system diagram for the ADSP-2105, with one
serial I/O device, a boot EPROM, and optional external
program and data memory. A total of 14.5K words of data
memory and 15K words of program memory is addressable for
the ADSP-2105.
Figure 5 shows a system diagram for the ADSP-2111, with two
serial I/O devices, a host processor, a boot EPROM, and
optional external program and data memory. A total of 15K
words of data memory and 16K words of program memory is
addressable.
Programmable wait-state generation allows the processors to
easily interface to slow external memories.
The ADSP-2101, ADSP-2103, ADSP-2115, and ADSP-2111
processors also provide either: one external interrupt (IRQ2)
and two serial ports (SPORT0, SPORT1), or three external
interrupts (IRQ2, IRQ1, IRQ0) and one serial port (SPORT0).
The ADSP-2105 provides either: one external interrupt (IRQ2)
and one serial port (SPORT1), or three external interrupts
(IRQ2, IRQ1, IRQ0) with no serial port.
Clock Signals
The ADSP-21xx processors’ CLKIN input may be driven by a
crystal or by a TTL-compatible external clock signal. The
CLKIN input may not be halted or changed in frequency during
operation, nor operated below the specified low frequency limit.
If an external clock is used, it should be a TTL-compatible
signal running at the instruction rate. The signal should be
connected to the processor’s CLKIN input; in this case, the
XTAL input must be left unconnected.
Because the ADSP-21xx processors include an on-chip oscillator circuit, an external crystal may also be used. The crystal
should be connected across the CLKIN and XTAL pins, with
two capacitors connected as shown in Figure 2. A parallelresonant, fundamental frequency, microprocessor-grade crystal
should be used.

ADSP-21xx
A clock output signal (CLKOUT) is generated by the processor,
synchronized to the processor’s internal cycles.
Reset
The RESET signal initiates a complete reset of the ADSP-21xx.
The RESET signal must be asserted when the chip is powered
up to assure proper initialization. If the RESET signal is applied
during initial power-up, it must be held long enough to allow
the processor’s internal clock to stabilize. If RESET is activated
at any time after power-up and the input clock frequency does
not change, the processor’s internal clock continues and does
not require this stabilization time.
The power-up sequence is defined as the total time required for
the crystal oscillator circuit to stabilize after a valid VDD is
applied to the processor and for the internal phase-locked loop
(PLL) to lock onto the specific crystal frequency. A minimum of
2000 tCK cycles will ensure that the PLL has locked (this does
not, however, include the crystal oscillator start-up time).
During this power-up sequence the RESET signal should be
held low. On any subsequent resets, the RESET signal must
meet the minimum pulse width specification, tRSP.
To generate the RESET signal, use either an RC circuit with an
external Schmidt trigger or a commercially available reset IC.
(Do not use only an RC circuit.)

Figure 5. ADSP-2111 System
The data lines are bidirectional. The program memory select
(PMS) signal indicates accesses to program memory and can be
used as a chip select signal. The write (WR) signal indicates a
write operation and is used as a write strobe. The read (RD)
signal indicates a read operation and is used as a read strobe or
output enable signal.
The RESET input resets all internal stack pointers to the empty
stack condition, masks all interrupts, and clears the MSTAT
register. When RESET is released, the boot loading sequence is
performed (provided there is no pending bus request and the
chip is configured for booting, with MMAP = 0). The first
instruction is then fetched from internal program memory
location 0x0000.
Program Memory Interface
The on-chip program memory address bus (PMA) and on-chip
program memory data bus (PMD) are multiplexed with the onchip data memory buses (DMA, DMD), creating a single
external data bus and a single external address bus. The external
data bus is bidirectional and is 24 bits wide to allow instruction
fetches from external program memory. Program memory may
contain code and data.
The external address bus is 14 bits wide. For the ADSP-2101,
ADSP-2103, and ADSP-2111, these lines can directly address
up to 16K words, of which 2K are on-chip. For the ADSP-2105
and ADSP-2115, the address lines can directly address up to
15K words, of which 1K is on-chip.
The ADSP-21xx processors write data from their 16-bit
registers to 24-bit program memory using the PX register to
provide the lower eight bits. When the processor reads 16-bit
data from 24-bit program memory to a 16-bit data register, the
lower eight bits are placed in the PX register.
The program memory interface can generate 0 to 7 wait states
for external memory devices; default is to 7 wait states after
RESET.
Program Memory Maps
Program memory can be mapped in two ways, depending on the
state of the MMAP pin. Figure 6 shows the two program
memory maps for the ADSP-2101, ADSP-2103, and
ADSP-2111. Figure 8 shows the program memory maps for the
ADSP-2105 and ADSP-2115. Figures 7 and 9 show the
program memory maps for the ADSP-2161/62 and ADSP-2163/
64, respectively.

Data Memory Interface
All Processors
The data memory address bus (DMA) is 14 bits wide. The
bidirectional external data bus is 24 bits wide, with the upper 16
bits used for data memory data (DMD) transfers.
The remaining 14K of data memory is located off-chip. This
external data memory is divided into five zones, each associated
with its own wait-state generator. This allows slower peripherals
to be memory-mapped into data memory for which wait states
are specified. By mapping peripherals into different zones, you
can accommodate peripherals with different wait-state requirements. All zones default to seven wait states after RESET.
The data memory select (DMS) signal indicates access to data
memory and can be used as a chip select signal. The write (WR)
signal indicates a write operation and can be used as a write
strobe. The read (RD) signal indicates a read operation and can
be used as a read strobe or output enable signal.
The ADSP-21xx processors support memory-mapped I/O, with
the peripherals memory-mapped into the data memory address
space and accessed by the processor in the same manner as data
memory.
Data Memory Map
ADSP-2101/ADSP-2103/ADSP-2111
For the ADSP-2101, ADSP-2103, and ADSP-2111, on-chip
data memory RAM resides in the 1K words beginning at
address 0x3800, as shown in Figure 10. Data memory locations
from 0x3C00 to the end of data memory at 0x3FFF are
reserved. Control and status registers for the system, timer,
wait-state configuration, and serial port operations are located in
this region of memory.
ADSP-2105/ADSP-2115
For the ADSP-2105 and ADSP-2115, on-chip data memory
RAM resides in the 512 words beginning at address 0x3800,
also shown in Figure 10. Data memory locations from 0x3A00
to the end of data memory at 0x3FFF are reserved. Control and
status registers for the system, timer, wait-state configuration,
and serial port operations are located in this region of memory.

Three bits in the processors’ System Control Register select
which page is loaded by the boot memory interface. Another bit
in the System Control Register allows the forcing of a boot
loading sequence under software control. Boot loading from
Page 0 after RESET is initiated automatically if MMAP = 0.
The boot memory interface can generate zero to seven wait
states; it defaults to three wait states after RESET. This allows
the ADSP-21xx to boot from a single low cost EPROM such as
a 27C256. Program memory is booted one byte at a time and
converted to 24-bit program memory words.
The BMS and RD signals are used to select and to strobe the
boot memory interface. Only 8-bit data is read over the data
bus, on pins D8-D15. To accommodate up to eight pages of
boot memory, the two MSBs of the data bus are used in the
boot memory interface as the two MSBs of the boot memory
address: D23, D22, and A13 supply the boot page number.
The BR signal is recognized during the booting sequence. The
bus is granted after loading the current byte is completed. BR
during booting may be used to implement booting under control
of a host processor.
Bus Interface
The ADSP-21xx processors can relinquish control of their data
and address buses to an external device. When the external
device requires control of the buses, it asserts the bus request
signal (BR). If the ADSP-21xx is not performing an external
memory access, it responds to the active BR input in the next
cycle by:

On the ADSP-2101, ADSP-2103, and ADSP-2111, boot
memory is an external 64K by 8 space, divided into eight
separate 8K by 8 pages. On the ADSP-2105 and ADSP-2115,
boot memory is a 32K by 8 space, divided into eight separate

ADSP-21xx
If the ADSP-21xx is performing an external memory access
when the external device asserts the BR signal, it will not threestate the memory interfaces or assert the BG signal until the
cycle after the access completes (up to eight cycles later depending on the number of wait states). The instruction does not need
to be completed when the bus is granted; the ADSP-21xx will
grant the bus in between two memory accesses if an instruction
requires more than one external memory access.
When the BR signal is released, the processor releases the BG
signal, re-enables the output drivers and continues program
execution from the point where it stopped.
The bus request feature operates at all times, including when
the processor is booting and when RESET is active. If this
feature is not used, the BR input should be tied high (to VDD).
Devices for conversion into a ADSP-216x ROM product.
The ADSP-2101 EZ-ICE emulator can be used for development of ADSP-216x systems. For the 3.3 V ADSP-2162 and
ADSP-2164, a voltage converter interface board provides 3.3 V
emulation.
Additional overlay memory is used for emulation of ADSP2161/62 systems. It should be noted that due to the use of offchip overlay memory to emulate the ADSP-2161/62, a performance loss may be experienced when both executing instructions and fetching program memory data from the off-chip
overlay memory in the same cycle. This can be overcome by
locating program memory data in on-chip memory.
Ordering Procedure for ADSP-216x ROM Processors
To place an order for a custom ROM-coded ADSP-2161,
ADSP-2162, ADSP-2163, or ADSP-2164 processor, you must:
Low Power IDLE Instruction
The IDLE instruction places the ADSP-21xx processor in low
power state in which it waits for an interrupt. When an interrupt
occurs, it is serviced and execution continues with instruction
following IDLE. Typically this next instruction will be a JUMP
back to the IDLE instruction. This implements a low-power
standby loop.
The IDLE n instruction is a special version of IDLE that slows
the processor’s internal clock signal to further reduce power
consumption. The reduced clock frequency, a programmable
fraction of the normal clock rate, is specified by a selectable
divisor, n, given in the IDLE instruction. The syntax of the
instruction is:
1. Complete the following forms contained in the ADSP ROM
Ordering Package, available from your Analog Devices sales
representative:
ADSP-216x ROM Specification Form
ROM Release Agreement
ROM NRE Agreement & Minimum Quantity Order (MQO)
Acceptance Agreement for Pre-Production ROM Products
2. Return the forms to Analog Devices along with two copies of
the Memory Image File (.EXE file) of your ROM code. The
files must be supplied on two 3.5" or 5.25" floppy disks for
the IBM PC (DOS 2.01 or higher).
3. Place a purchase order with Analog Devices for non-recurring
engineering changes (NRE) associated with ROM product
development.
IDLE n;
where n = 16, 32, 64, or 128.
The instruction leaves the chip in an idle state, operating at the
slower rate. While it is in this state, the processor’s other
internal clock signals, such as SCLK, CLKOUT, and the timer
clock, are reduced by the same ratio. Upon receipt of an
enabled interrupt, the processor will stay in the IDLE state for
up to a maximum of n CLKIN cycles, where n is the divisor
specified in the instruction, before resuming normal operation.
After this information is received, it is entered into Analog
Devices’ ROM Manager System which assigns a custom ROM
model number to the product. This model number will be
branded on all prototype and production units manufactured to
these specifications.
When the IDLE n instruction is used, it slows the processor’s
internal clock and thus its response time to incoming interrupts–
the 1-cycle response time of the standard IDLE state is increased by n, the clock divisor. When an enabled interrupt is
received, the ADSP-21xx will remain in the IDLE state for up
to a maximum of n CLKIN cycles (where n = 16, 32, 64, or
128) before resuming normal operation.
To minimize the risk of code being altered during this process,
Analog Devices verifies that the .EXE files on both floppy disks
are identical, and recalculates the checksums for the .EXE file
entered into the ROM Manager System. The checksum data, in
the form of a ROM Memory Map, a hard copy of the .EXE file,
and a ROM Data Verification form are returned to you for
inspection.
When the IDLE n instruction is used in systems that have an
externally generated serial clock (SCLK), the serial clock rate
may be faster than the processor’s reduced internal clock rate.
Under these conditions, interrupts must not be generated at a
faster rate than can be serviced, due to the additional time the
processor takes to come out of the IDLE state (a maximum of n
CLKIN cycles).
ADSP-216x Prototyping
You can prototype your ADSP-216x system with either the
ADSP-2101 or ADSP-2103 RAM-based processors. When code
is fully developed and debugged, it can be submitted to Analog

ADSP-21xx
Functional Differences for Older Revision Devices
A signed ROM Verification Form and a purchase order for
production units are required prior to any product being
manufactured. Prototype units may be applied toward the
minimum order quantity.
Older revisions of the ADSP-21xx processors have slight
differences in functionality. The two differences are as follows:
•
Bus Grant (BG) is asserted in the same cycle that Bus
Request (BR) is recognized (i.e. when setup and hold time
requirements are met for the BR input). Bus Request input is
a synchronous input rather than asynchronous. (In newer
revision devices, BG is asserted in the cycle after BR is
recognized.)
•
Only the standard IDLE instruction is available, not the
clock-reducing IDLE n instruction.
Upon completion of prototype manufacture, Analog Devices
will ship prototype units and a delivery schedule update for
production units. An invoice against your purchase order for the
NRE charges is issued at this time.
There is a charge for each ROM mask generated and a minimum order quantity. Consult your sales representative for
details. A separate order must be placed for parts of a specific
package type, temperature range, and speed grade.
To determine the revision of a particular ADSP-21xx device,
inspect the marking on the device. For example, an ADSP-2101
of revision 6.0 will have the following marking:

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADSP-21xx processors feature proprietary ESD protection circuitry to dissipate high energy
electrostatic discharges (Human Body Model), permanent damage may occur to devices subjected
to such discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality. Unused devices must be stored in conductive foam or shunts,
and the foam should be discharged to the destination socket before the devices are removed. Per
method 3015 of MIL-STD-883, the ADSP-21xx processors have been classified as Class 1 devices.

Output Enable Time
Output pins are considered to be enabled when they have made
a transition from a high-impedance state to when they start
driving. The output enable time (t E NA) is the interval from
when a reference signal reaches a high or low voltage level to
when the output has reached a specified high or low trip point,
as shown in Figure 15. If multiple pins (such as the data bus)
are enabled, the measurement value is that of the first pin to
start driving.
Output Disable Time
Output pins are considered to be disabled when they have
stopped driving and started a transition from the measured
output high or low voltage to a high impedance state. The
output disable time (tDIS) is the difference of tMEASURED and
tDECAY, as shown in Figure 15. The time tMEASURED is the
interval from when a reference signal reaches a high or low
voltage level to when the output voltages have changed by 0.5 V
from the measured output high or low voltage.

CAPACITIVE LOADING
To determine total power dissipation in a specific application,
the following equation should be applied for each output:

RISE TIME (0.8V - 2.0V) – ns
Example:
In an ADSP-2111 application where external data memory is
used and no other outputs are active, power dissipation is
calculated as follows:
Assumptions:
•
External data memory is accessed every cycle with 50% of the
address pins switching.
•
External data memory writes occur every other cycle with
50% of the data pins switching.
•
•
Each address and data pin has a 10 pF total load at the pin.

Output Enable Time
Output pins are considered to be enabled when they have made
a transition from a high-impedance state to when they start
driving. The output enable time (t E NA) is the interval from
when a reference signal reaches a high or low voltage level to
when the output has reached a specified high or low trip point,
as shown in Figure 21. If multiple pins (such as the data bus)
are enabled, the measurement value is that of the first pin to
start driving.
Output Disable Time
Output pins are considered to be disabled when they have
stopped driving and started a transition from the measured
output high or low voltage to a high impedance state. The
output disable time (tDIS) is the difference of tMEASURED and
tDECAY, as shown in Figure 21. The time tMEASURED is the
interval from when a reference signal reaches a high or low
voltage level to when the output voltages have changed by 0.5 V
from the measured output high or low voltage.

If IRQx and FI inputs meet t IFS and tIFH setup/hold requirements, they will be recognized during the current clock cycle; otherwise they will be recognized
during the following cycle. (Refer to the “Interrupt Controller” section in Chapter 3, Program Control, of the ADSP-2100 Family User’s Manual for further
information on interrupt servicing.)

Edge-sensitive interrupts require pulse widths greater than 10 ns. Level-sensitive interrupts must be held low until serviced.

NOTES
1
If BR meets the t BS and tBH setup/hold requirements, it will be recognized in the current processor cycle; otherwise it is recognized in the following cycle. BR requires
a pulse width greater than 10 ns.
2
For 25 MHz only the minimum frequency dependency formula for t SEC = (0.25tCK – 8.5).
Section 10.2.4, “Bus Request/Grant,” on page 212 of the ADSP-2100 Family User’s Manual (1st Edition, 1993) states that “When BR is recognized, the processor
responds immediately by asserting BG during the same cycle.” This is incorrect for the current versions of all ADSP-21xx processors: BG is asserted in the cycle after
BR is recognized. No external synchronization circuit is needed when BR is generated as an asynchronous signal.

TIMING PARAMETERS (ADSP-2103/2162/2164)
GENERAL NOTES
Use the exact timing information given. Do not attempt to
derive parameters from the addition or subtraction of others.
While addition or subtraction would yield meaningful results for
an individual device, the values given in this data sheet reflect
statistical variations and worst cases. Consequently, you cannot
meaningfully add parameters to derive longer times.
Timing requirements apply to signals that are controlled by
circuitry external to the processor, such as the data input for a
read operation. Timing requirements guarantee that the
processor operates correctly with other devices.
MEMORY REQUIREMENTS
The table below shows common memory device specifications
and the corresponding ADSP-21xx timing parameters, for your
convenience.
TIMING NOTES
Switching characteristics specify how the processor changes its
signals. You have no control over this timing—circuitry external
to the processor must be designed for compatibility with these
signal characteristics. Switching characteristics tell you what the
processor will do in a given circumstance. You can also use
switching characteristics to ensure that any timing requirement
of a device connected to the processor (such as memory) is
satisfied.

If IRQx and FI inputs meet t IFS and tIFH setup/hold requirements, they will be recognized during the current clock cycle; otherwise they will be recognized during the
following cycle. (Refer to the “Interrupt Controller” section in Chapter 3, Program Control, of the ADSP-2100 Family User’s Manual for further information on
interrupt servicing.)

Edge-sensitive interrupts require pulse widths greater than 10 ns. Level-sensitive interrupts must be held low until serviced.

NOTES
1
If BR meets the t BS and tBH setup/hold requirements, it will be recognized in the current processor cycle; otherwise it is recognized in the following cycle. BR
requires a pulse width greater than 10 ns.
Section 10.2.4, “Bus Request/Grant,” of the ADSP-2100 Family User’s Manual (1st Edition, ©1993) states that “When BR is recognized, the processor
responds immediately by asserting BG during the same cycle.” This is incorrect for the current versions of all ADSP-21xx processors: BG is asserted in the
cycle after BR is recognized. No external synchronization circuit is needed when BR is generated as an asynchronous signal.
