Introduction
Traditionally, programmable logic devices have been programmed on external device
programmers that provide the necessary programming signals and algorithms to program the devices. With the advent of In-System Programming (ISP), ISP devices can
now be programmed on your own circuit board. This manual describes the design methods and requirements for implementing in-system Programming on Atmel ISP Complex
Programmable Logic Devices (CPLDs). All devices in the ATF15xx family are ISP capable CPLDs (except ATF1500/A/AL/ABV), and ISP is implemented on these devices
through the Joint Test Action Group (JTAG) interface. The following devices are supported by the Atmel-ISP software.
• ATF1502AS/ASL/ASV/ASVL
• ATF1504AS/ASL/ASV/ASVL
• ATF1508AS/ASL/ASV/ASVL
The three essential components for in-system programming are the Atmel-ISP software,
ISP hardware board and ISP download cable. These components and their usage will
be discussed in detail in this user guide.
In addition to these three components, a JEDEC file is also necessary to program any
Atmel ISP devices. This JEDEC file can be created by compiling a design file using a
compiler software that supports the Atmel ISP devices. Atmel also provides translator
software (POF2JED.EXE) to convert output files from the competitor’s programming format to a JEDEC file compatible with the Atmel ISP family of devices. This conversion
utility is available on Atmel’s web site and BBS. For further information on POF2JED,
please refer to the application note, “ATF15xx Product Family Conversion”, available on
Atmel’s web site, BBS and Fax-on-Demand. After you have created the JEDEC files for
all Atmel ISP devices, you are ready to program them on your circuit/Atmel-ISP board.
Using the Atmel-ISP software, download cable and ISP hardware board, you can program, verify, blank check, erase, secure and read from any Atmel ISP device directly
from your personal computer while the devices are still on the circuit boards.

Introduction
1.1 Benefits In-system programming allows you to program and reprogram devices after they are
soldered onto your circuit board. ISP eliminates the extra handling step required in the
manufacturing process to program the devices on an external programmer before placing them on your circuit board. Eliminating this step reduces the possibility of damaging
the delicate leads of high pin count surface mount devices or damaging the device
through electrostatic discharge (ESD). ISP also allows you to make design changes and
field upgrades without removing the Atmel ISP devices from the circuit board. In addition, ISP allows you to use your Automatic Test Equipment (ATE) to perform ISP
operations on your ISP devices and integrate these ISP operations with the normal production test flow.
1.2 Atmel JTAG ISP Interface
1.2.1 Single-device Programming
The Atmel JTAG ISP interface is a 4-pin, 3- or 5-volt interface compatible with the Joint
Test Action Group (JTAG) IEEE 1149.1a-1993 Standard. All Atmel ISP devices can be
programmed, verified and erased through this interface. The JTAG interface is a serial
interface consisting of the TCK, TMS, TDI and TDO signals, and a JTAG Test Access
Port (TAP) Controller. The TCK pin is the serial data clock. Programming data is clocked
by this pin. The TDI pin is the serial data input. It is used to shift programming data into
the Atmel device. The TDO pin is the serial data output. It is used to shift out data from
the Atmel device. The TMS pin is a mode select pin. It controls the state of the JTAG
TAP controller.
Atmel ISP devices are fully JTAG-compatible and support the required Boundary Scan
Test (BST) operations specified in the JTAG standard. Atmel ISP devices can be configured to be a part of a JTAG BST chain with other JTAG devices for in-circuit testing of
your system board. With this feature, you can test Atmel CPLDs along with other
devices without resorting to bed-of-nails testing.
For more information about Atmel ISP, BST or the POF-to-JEDEC translator, please
contact Atmel PLD Applications at:
Hotline: 1-408-436-4333
E-mail: pld@atmel.com
URL: www.atmel.com
The Atmel JTAG ISP interface can be configured to program a single Atmel ISP device.
The JTAG configuration for a single device is shown in Figure 1-1. When the Atmel ISP
device is configured in this way, a register appears between the TDI and TDO pins of
the device. The size of the register depends on the JTAG instruction width and the data
being shifted in for that instruction. The JTAG interface pins for the Atmel ISP device
must be connected to a 10-pin header on your circuit board. This header mates with the
ISP download cable and allows the Atmel-ISP software to transfer programming data
from your personal computer to the Atmel ISP device. The pinout for the JTAG pins for
different Atmel ISP devices is listed in Table 1-1.

Note: You will need to reserve space on your circuit board to accommodate a 10-pin
male header for the JTAG interface. The pinout for this header must match the
Atmel-ISP cable connector pinout. The JTAG interface pins for each Atmel
device must also be connected to this header.
Atmel ISP devices can be configured as part of a JTAG daisy chain. Once the daisy
chain is configured, multiple Atmel ISP devices can be programmed at the same time
(Parallel ISP). Figure 1-2 shows the configuration for multiple-device programming.

TDI, TMS, TCK and TDO comprise the JTAG interface. The ISP software allows you to
create a JTAG daisy chain for multiple devices, including non-Atmel devices, and implement parallel ISP for Atmel devices.
To create a JTAG daisy chain to implement parallel ISP, perform the following steps:
1. Connect the TMS and TCK pin for each device in the JTAG chain to the appropriate pins on the 10-pin header on your circuit board.
2. Connect the TDI pin from the first device to the TDI pin on the 10-pin header.
3. Connect the TDO pin from first device to the TDI pin of the next device. Continue
this process until all except the last one are connected.
4. Connect the TDO pin from the last device to the TDO pin on the 10-pin header.

Introduction
A device residing in any location in the JTAG chain can be programmed exclusive of all
others. You can use the Atmel-ISP software to place all other devices except the one to
be programmed in the JTAG Bypass mode. When the other devices are placed in this
mode, a 1-bit flow-through register appears between the TDI and TDO pins for these
devices. During a programming operation, JTAG programming data passes through
devices in the JTAG Bypass mode but is loaded into the device that is to be programmed. This allows only the device you want to program to be loaded with JEDEC
fuse data.
1.3 Design Considerations
Performing ISP on Atmel ISP devices requires that you reserve design resources for the
JTAG interface. You will need to reserve four I/O pins for the TMS, TDI, TDO and TCK
pins. The pin numbers for these pins depend on which Atmel ISP device you are using
and its package type. Refer to Table 1-1 for pinout information. The JTAG standard also
requires that the TMS and TDI pins be pulled up for each device in the JTAG chain. The
Atmel ISP devices have an internal pull-up feature for these pins which, when enabled,
saves the need for external pull-up resistors. Once you have reserved logic resources
for the JTAG interface, you can program, verify and erase any Atmel ISP device using
the Atmel-ISP software.
Note: Even though you must reserve certain I/O pins in your design for the JTAG
interface, you can still implement buried logic functions in the macrocells associated with these pins.

To use ISP to program Atmel devices, you must enable the JTAG interface. An optional
but recommended practice is to also enable the TMS and TDI internal pull-ups. Enabling
the JTAG interface requires choosing specific Atmel device types before compiling your
™
design. This procedure is outlined below for Atmel-Synario
and Atmel-WinCUPL™. If
you need to enable Atmel fitter properties for other software platforms, please contact
Atmel PLD Applications.
1.3.1 JTAG Interface with Atmel-Synario
To enable the JTAG interface with Atmel-Synario and multi-vendor Synario, you’ll need
to select an Atmel ISP device type first. You can change fitter property settings to enable
the TDI and TMS internal pull-ups or the pin-keeper circuits.
Note: If you use an Atmel ISP device type for a design that uses the JTAG interface
pins as logic I/O pins, Atmel-Synario will generate an error.

into the device, will keep the JTAG interface enabled and (optionally) enable the
internal TMS and TDI pull-ups and pin-keeper circuits.
Note: Selecting an Atmel ISP device type will automatically enable the JTAG interface
by default when Atmel-Synario runs the Atmel device fitter.
™
To enable the JTAG interface with Atmel-WinCUPL and CUPL Total Designer
software
from Logical Devices, you’ll need to select an Atmel ISP device type first. You can then
change the fitter property settings to enable the TDI and TMS internal pull-ups, or other
options. For example, pin-keeper circuits.
Note: If you use an Atmel ISP device type for a design that uses the JTAG interface
pins as logic I/O pins, Atmel-WinCUPL will generate an error.
1. For Atmel-WinCUPL V4.8, click once on Options from the main menu, then click
once on Select Device. This will open the Select Device dialog box.
For Atmel-WinCUPL V5.1, click once on Options from the main menu, then click

Introduction
8. Atmel-WinCUPL will compile the design and spawn the Atmel device fitter. If the
design fits, a JEDEC file is automatically created. When the JEDEC file is programmed into the device, the JTAG interface, (optionally) internal TMS and TDI
pull-ups and (optionally) pin-keeper circuits will be enabled.
Note: Selecting an Atmel ISP device type will automatically enable the JTAG interface
by default when Atmel-WinCUPL runs the Atmel device fitter.
If you have designs that prevent you from reserving resources for the JTAG interface or
you do not wish to use ISP, you must select an Atmel non-ISP device type. See
Table 1-2 below for a listing. You can then reprogram the device using an external
device programmer.
Table 1-2 shows a list of Atmel ISP and Atmel non-ISP device types for Atmel-Synario
and Atmel-WinCUPL.

Section 3
Atmel-ISP Software
The Atmel-ISP software, ATMISP, is the primary means for implementing ISP on Atmel
ISP devices. It can be used from your personal computer to implement ISP or to generate an output file (Serial Vector Format, SVF file) suitable for use on ATE systems. The
Atmel-ISP software is a Windows-based program that runs on Windows 3.x, Windows
95, Windows 98, and Windows NT platforms (Windows NT requires a different software
package, ATMISPNT). If you want to use the Atmel-ISP software to implement ISP from
your personal computer, you will need the Atmel-ISP cable. Otherwise, it is not required.
To get a copy of the software, you can order it from your local Atmel sales representative or download it from our web site. After you receive the software, you must install it
before using. When it is successfully installed, the Atmel-ISP Program and Help icons
are automatically created. Figure 3-1 shows the ATMISP main menu.
Figure 3-1. ATMISP Main Menu
With the Atmel-ISP software you can:
Program, verify, erase, blank check, read and secure Atmel ISP devices on your
circuit board or the Atmel-ISP board
Implement parallel ISP (program multiple Atmel ISP devices at once) on your circuit
board
Program Atmel ISP devices before using them in your circuit board (requires
Atmel-ISP board)
Program Atmel ISP devices exclusive of other devices
Generate SVF files for ATE systems (might require translator software utility)
The Atmel-ISP software requires you to create a JTAG chain file, which describes the
characteristics of all Atmel and non-Atmel ISP devices configured on your circuit board.
You can use the software to add, edit or delete items in the JTAG chain file. Any Atmel
ISP device in the JTAG chain can be programmed with this software. You can also
Atmel ATF15xx Family: ISP Devices User Guide 3-1
Rev. 1936A-07/01
Atmel-ISP Software
configure an Atmel device in the JTAG Bypass mode to prevent certain Atmel ISP
devices from being programmed. Non-Atmel ISP devices must be configured in the
JTAG Bypass mode.
Once you have configured the JTAG chain, the software will prompt you to link JEDEC
files to the appropriate Atmel ISP devices you want to program. The Atmel-ISP software
will automatically implement parallel ISP on your circuit board if more than one Atmel
device is linked.
The Atmel-ISP software cannot execute different ISP operations for Atmel devices in
your JTAG chain. You can only perform the same ISP operation on several devices at
the same time. For example, you can erase all devices in the chain at the same time, but
you cannot erase one device while programming another in the same JTAG chain. The
only exception is the Bypass instruction where it can be used in combination with any
other JTAG instruction. For example, you can program the first device and bypass all
remaining devices in your JTAG chain.
The Atmel-ISP software, if used with an Atmel-ISP board, can perform programming
operations on only one device at a time. Attempting to use the software with the
Atmel-ISP board to program multiple devices will generate an error. A customer’s circuit
board is required to program multiple devices via ISP.
Before running ATMISP, make sure to apply power to your circuit board or the
Atmel-ISP board before attaching the 25-pin connector on the ISP cable to your PC. If
you get the message “Check board, chips and power supplies,” that means the ATMISP
software is not able to communicate with the ISP hardware properly.
For more informa-
tion, please refer to Section 7, “Troubleshooting”.
The ATMISP software allows you to use either the Atmel-ISP cable or the Byte-
Blaster/ByteBlasterMV cable to program the Atmel ISP devices. Refer to the “ATMISP
Commands” section for more information on how to select the appropriate download
cable type.
The ATMISP software also allows you to generate Serial Vector Format files. ATE vendors that support the SVF file format can execute ISP on Atmel ISP devices only. If you
need to program devices from different vendors with a single SVF file, you’ll need to use
third-party software that supports these features. Translator software utilities such as
the Atmel SVF2PCF translator and SVF2JAM
™
are available to convert the SVF files
into the appropriate format files to be used by different ATE systems. Contact Atmel
PLD Applications for more information.

3.1 ATMISP Commands
3.1.1 Device Properties Dialog Box
The Device Properties dialog box will appear when you are creating a new chain file or
editing an existing chain file. This dialog box allows you to specify the ISP operation you
want to perform for each Atmel ISP device in your JTAG hardware chain. Some of the
ISP commands and operations available on the Atmel-ISP software are discussed
below. There is also an online help available for all the commands discussed below.
Just click on Help...Contents from the Atmel-ISP software main menu.
The five sections of the Device Properties dialog box are outlined below.
Device Type – Click to choose a specific Atmel ISP device. If there are non-Atmel
ISP devices in your chain, you must select Unknown.
JTAG Instruction Width – This dialog item defaults to 10 bits, and all Atmel ISP
devices have 10-bit JTAG instruction width. Some non-Atmel ISP devices may have
JTAG instruction widths different from the default value. Make sure to specify the
correct instruction width for those devices.
IDCODE Register Option – Make sure this option is always selected before
executing any ISP operation on Atmel devices. Some non-Atmel ISP devices do not
power-up with the IDCODE register available. Deselect this option for these devices.
JTAG Instruction – This dialog box specifies the ISP operation to be performed. All
JTAG operations are listed below:
1. Bypass – This instruction bypasses the selected device from responding to
ISP operations. It is required for all non-Atmel ISP devices in your JTAG
hardware chain.
2. Program/Verify – This instruction will erase, program and verify the Atmel
ISP device.
3. Erase – Erases the appropriate Atmel ISP device. This is the recommended
state for all Atmel ISP devices prior to programming.
4. Blank Check – This operation checks to see if a device is blank. If it isn’t, an
error will be generated. Devices previously secured may pass Blank Check.
However, this does not mean that they are blank. To unsecure a device, simply erase it.
5. Verify – This operation performs a fuse verify on the device. The JEDEC
data programmed into the device is compared with the JEDEC file. If the
fuses do not verify, an error message is generated.
6. Load – Loads the fuse data programmed in the Atmel ISP device into RAM.
If you specify a JEDEC file with this command, the fuse data is saved to that
file.
7. Secure – Secures the Atmel ISP devices to prevent unauthorized loading of
their fuse data.
8. Program/Verify/Secure – This ISP operation will program, fuse verify, secure
and then verify that the device is secured.
9. Verify S e c u r e – This operation will verify that an Atmel ISP device is
secured. Verify Secure can be performed on only one device at a time. All
other ISP devices in a multi-device chain system should be set to the Bypass
mode.
JEDEC File Name – This dialog box specifies the JEDEC file and its directory that is
linked to the ISP device. For the Program, Program/Verify, Program/Verify/Secure,
Verify and Load commands, you must specify a JEDEC file. To select a JEDEC file,
click on the Browse button. The ISP software will prompt you to browse the
Atmel ATF15xx Family: ISP Devices User Guide 3-3

3.1.2 Description of ATMISP File Menu Commands
New This command allows you to create a new chain file. The chain file is
needed so that you can execute ISP operations for the Atmel ISP
device(s) in the JTAG chain on your circuit board or ISP board. After
you execute this command, the ISP software will prompt you to specify the number of devices in your JTAG chain.
Note: If you are using the Atmel-ISP software with the Atmel-ISP
board, you must enter 1 at this prompt.
Open This command opens an existing chain file. The software will prompt
you to either enter the name of the chain file or to browse to the
appropriate directory where it is located. The software defaults to
defining the chain file with a *.chn suffix. Once the chain file is open, it
is ready to be executed by the ISP software to perform ISP operations on your JTAG device chain.
Close This command allows you to close an already-open chain file. Only
one chain file can be opened at a time. To open a new chain file you
must use this command to close the existing one so that a new chain
file can be used. If you attempt to close an open chain file without
saving it, the ISP software will prompt you to save it first. If you click
No, the chain file is lost and you will have to enter new information.
Save This command allows you to save an open chain file for use at a later
time. It is recommended that you always save your chain file after you
have entered the ISP operations you want to perform for all devices in
your JTAG chain.
Save As This command allows you to save a chain file with a different file
name than the default name chosen by the ISP software.
Port Setup This command allows you to specify a parallel port address that is dif-
ferent from the default port setting (LPT1 - 378H) specified by the
software. The software will prompt you to select LPT2 (278H). If your
port address isn’t one of these addresses, click No and enter the new
port address you want the software to use. The port setting will
remain in effect until you change it or until the software is closed.
If your computer’s BIOS is set to AUTO, you may have some problems getting the ISP software to communicate with your target
system. Change your BIOS setting to either the ECP or EPP mode.
Another option is to use Windows 95/98 to configure the correct ECP
or EPP driver. Windows NT 3.x and above requires a separate installation of the ISP software (ATMISPNT) to communicate with the
parallel port.
Note: To quickly determine what the parallel port address setting is,
execute the View Chain File command to see your chain file.
The port address will be shown in the top left-hand corner.

Atmel-ISP Software
Self-Calibrate This option is intended to help you if you are having problems getting
the Atmel-ISP software to communicate between your PC’s parallel
port and either your circuit board or the Atmel-ISP board. When this
option runs, the software dynamically adjusts the communication
speed between the parallel port on your PC and the Atmel ISP
devices in your JTAG chain.
If the self-calibration process is successful, the software was able to
find a reliable transfer speed to communicate with your hardware. It
will save this transfer speed as long as the main menu remains open.
If you save your chain file after running the Self-Calibrate option, the
transfer speed will also be saved. Therefore, the next time you run
the software with this chain file, it will communicate at the specified
transfer speed in the chain file.
If the self-calibration process fails, the software automatically selects
the slowest transfer rate. It will use this rate for all further ISP operations unless the self-calibration process is repeated and the software
selects a faster transfer rate. If you do not use this option, the software defaults to using the fastest transfer speed to communicate with
your hardware.
With V3.00 or later ATMISP software versions, this self-calibration
process will be automatically run when a chain file is executed for the
first time.

Exit This command exits the ISP software. If your chain file was not saved
This option is available in V3.00 or later software versions. It allows
you to directly control the transfer speed of the data between the parallel port on your PC and the JTAG device on your board. This feature
is useful when you are trying to communicate with your board with a
long (greater than 3 feet) parallel port cable.
Long cables can reduce signal rise and fall times and possibly create
crosstalk between JTAG interface signals. The combination or individual contribution of these effects may cause programming or verify
errors. Using the Manual Calibration setting allows you to adjust the
transfer rate to minimize these effects from interfering with programming. There are 4095 settings to choose from: 1 is the fastest setting
and 4095 is the slowest.
To use this feature, select this command and enter a number
between 1 and 4095. The default value is 1. The value selected will
be displayed as the calibration constant in the Chain File window. If
you are using a previously saved chain file, the Atmel-ISP software
will retain your calibration setting. Otherwise, it will default to using
the fastest speed.
before exiting, the ISP software will prompt you to save it. If you click
No, the chain file contents will be lost.
