DIP
A type of device package. An acronym for Dual In-line Package.
Download Data
A file operation that moves a data file from a host computer to the
programmer’s RAM or disk.
Download Echoing
Displays the data being downloaded.
Download Host Command
A command that is sent from the programmer to the host during a
download. The command tells the host to begin sending data to the
programmer.
E-MICRO
An acronym for Programmable Microcontroller. A type of device
technology.
EPROM
An acronym for Erasable Programmable Read-Only Memory. (Usually
refers to UV erasable memories.)
EEPROM
An acronym for Electronically Erasable Programmable Read-Only
Memory. The device can be either completely or partially erased
electrically in circuit or on the programmer.
Electronic ID
The combination of bytes that identify the device number and
manufacturer of a programmable device.
Enhanced Security Fuse
Capability
Found on EMICROs, the Enhanced Security Fuse Capability allows
security fuse data to be stored in a data file. For more information, or to
see if a device supports this capability, see the device manufacturer’s data
book.
ESD
An acronym for Electrostatic Discharge.
False Positive
In programming, a misprogrammed fuse that retains minimal
operational characteristics so that it passes the fuse test. These may be
inadequately programmed, or over-programmed so that they will fail
later in circuit.
File Transfer Operations
An operation involving the transfer of data between the programmer and
a host. Upload and download are file transfer operations.
Filename
The name of the disk file to use during file operations. The filename must
follow standard DOS conventions: up to eight alphanumeric characters,
followed by an optional three-character file extension, with the two fields
separated by a period. Examples of valid filenames would be
27256.dat
and
filename.c
.
Fuse Verification
A type of post-programming device check that checks the fuse pattern
programmed into a logic device with the pattern in user memory.
Fusemap
The fuse-level description portion of a programmable integrated circuit.
Fusemaps are typically files in JEDEC Standard #3A and are downloaded
to PLD programmers for device implementation.

Handshaking
The required sequence of signals for communication between two units.
The I/O bus protocol for a unit defines its handshaking requirements.
This is especially true for asynchronous I/O systems in which each signal
requires a response to complete an I/O operation.
High-speed Logic Drivers
A device test that increases the speed of the logic transitions between 0 to
1 and 1 to 0 of the test vector input states. This test is a diagnostic tool
designed to help debug and classify test vector failures. Specifically, this
test is designed to help identify vector transitions that are speed
dependent.
Host
A micro-mini, or mainframe computer used to control AutoSite in
Remote mode. You must use a software driver, such as Data I/O’s
TaskLink, to allow the computer to communicate with AutoSite.
Host Command
(download & upload)
The command that is sent from AutoSite to the host system during
uploading/downloading. See Download Host Command and Upload
Host Command.
I/O Address Offset
This value influences the beginning address where data is stored during a
file transfer operation. For uploads, the I/O Offset represents the address
to start loading a formatted data file. For downloads, the I/O Offset is
subtracted from the beginning address in the formatted data file. The
result is then added to the memory begin address to determine where the
block of data is loaded.
I/O Timeout
The amount of time that AutoSite will wait for a data transfer to begin.
I/O Translation Format
See Data Translation Format.
Illegal Bit
An illegal bit is when a device contains a programmed location and the
data file specifies that the location should be unprogrammed.
Illegal Bit Check
A test that determines whether or not a socketed device contains any
illegal bits.
Instrument Control Code
A 1-digit number that signals or controls data transfers. It also
implements a form of remote control that provides peripherals with flow
control beyond that provided by software handshaking.
JEDEC
Joint Electron Design Engineering Committee: a committee of
programmer and semiconductor manufacturers that provides common
standards for programmable issues. Examples of these standards include
acceptable test characters for PLDs and standard data transfer/
programming formats for PLDs. JEDEC Standard #3 is the industry
standard for PLD formats.
JEDEC Standard #3A
The standard PLD data translation format, as defined by JEDEC for PLD
design software to communicate with PLD programmers. It defines the
states of all fuses in the device (the fusemap) and may include test vectors
for device testing.

LCA
An acronym for Logic Cell Array.
LCC
An acronym for Leadless Chip Carrier—a type of device package. A 4-
sided device package with pads on the underside. Typically, the LCC is
used in surface mount applications.
LED
An acronym for Light Emitting diode. AutoSite has five LEDs: four on the
front panel and one on the disk drive.
Load Data
A device operation that moves device data into AutoSite. You can load
AutoSite with data from a device, from AutoSite’s internal disk drive, or
from a serial port (for example, from the Handler port).
Logic Verification
After programming a device, you can select test vector verification, fuse
verification, or both types of verification.
Master Device
A device that contains data you wish to program into another device. For
example, you would load data from a master device and then program
that data into a blank device.
MatchBook
A new type of socketing technology that makes handling surface-mount
devices easier. MatchBook device carriers are used with AutoSite’s stand
alone kit for single device programming.
Memory Begin Address
The first address, in hex, of the first byte of data to be used in device
operations. If the data source/destination is RAM, the memory begin
address is a RAM address. If the data source/destination is disk, the
memory begin address is the offset for a disk file.
Next Device
Used during serial set programming, this value specifies the next device
in the set. For example, if you are using 8-bit devices and have specified a
word width of 16 bits, it will require two devices to store each 16-bit
word. Depending on the value entered, the data programmed into the
next device will come from either even addresses or odd addresses.
Odd/even Byte Swap
Used during device operations for 16-bit devices, this option swaps the
Most Significant Bytes (MSB) and the Least Significant Bytes (LSB) of
16-bit words. AutoSite stores RAM data and disk file data with the
convention that the LSB of a 16-bit word resides in the even byte of
memory.
Output Record Size
The number of data bytes contained in each data record during upload.
Overblow
A condition in which fuses are blown that should not have been.
Overblown Fuse
A fuse that has been over-programmed such that the surrounding area
may have been damaged or such that fuse material splatter was created.
Splatter (or rattlers) can cause intermittent shorting.
PAL
An acronym for Programmable Array Logic. PALs are devices with
programmable AND and fixed OR arrays. This is a slightly different
architecture from a PROM or an FPLA. Other examples of PAL-type
architectures from other manufacturers include PEEL and GAL.
