I/O Timeout The amount of time that the programmer will wait for a data transfer to
begin.
I/O Translation Format See Translation Formats.
Illegal Bit An illegal bit occurs 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 provide common
standards for programmable issues. Examples 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.
JEDEC I/O translate DIP/
LCC Vectors
A feature on the programmer that translates test vectors for a device from
its DIP package to its PLCC/LCC package, allowing for the different
pinouts of the two package types.
JLCC An acronym for J-style Leadless Chip (or Ceramic) Carrier, a type of
device package. A device with hooked leads that are “open” at one end
(leads are usually on all four sides).
Job File A sequence of keystrokes that have been stored in a disk file and that can
be played back at a later time.
Keep Current Subscription
Service
A one-year renewable subscription to keep your product and
documentation up-to-date with the latest features and device support. A
Keep Current algorithm is an algorithm that has been downloaded from
the Keep Current area of the Data I/O Web site.
LCA An acronym for Logic Cell Array.
LCC An acronym for Leadless Chip Carrier, a type of device package. A 4-
sided ceramic package with pads on the underside for surface mount
applications.
LED An acronym for Light Emitting Diode. The programmer has five LEDs:
four on the top cover and one on the disk drive.
Load Data A device operation that moves device data into the programmer. You can
load the programmer with data from a device, from the programmer’s
internal disk drive, or from a serial port (for example, from the Remote
port).
Load Device A device operation that copies data from a master device into User
memory.
