QFP An acronym for Quad Flat Pack, a type of device package. A square or
rectangular device with leads on all four edges (leads can be either
straight or gull-wing). BQFP (Bumper Quad Flat Pack) is a QFP with
“bumpers” on the corners to prevent damage to leads. CQFP is a Ceramic
QFP or a QFP with carrier. Long Lead Carrier QFP is an ACTEL product
with long leads attached to a carrier grid for handling ease. PQFP (Plastic
carrier QFP) is a QFP with a plastic protective carrier for handling ease.
QFPCAR
is a QFP in a carrier. TQFP is a thin QFP.
QUIP An acronym for Quad Inline Package, a type of device package. Similar to
DIP, but with staggered long & short leads (leads on long sides).
Reboot The process of re-initializing the programmer. After rebooting, the
programmer is in the same state as if it had just been turned on.
Registered Devices Devices that contain registers, rather than being combinatorial only.
Registered devices are typically used for sequencers and state machine
designs. Typical examples are 16R8, 82S159, and 22V10.
Reject Option A post-programming device check that pulses the programmed device
with voltage to see if the device has programmed per specification. The
number of times a device is pulsed varies by manufacturer and by the
reject option you select.
Reminder Bar The bottom line of the screen. The reminder bar tells you what function
keys are available and what they will do if pressed.
Remote Mode Operating mode in which the programmer is controlled from a host
running a driver program. Device data files can be stored on the
programmer’s disk and on the host.
Security Fuse A location in a programmable device that, when programmed, secures
the device from readback: the data in the device is unreadable.
Security Fuse Data The actual data to program into the device’s security fuse.
Select Device A procedure that tells the programmer what device you will be using.
You can select a device by selecting the manufacturer and the device part
number.
Self-test A built-in self-diagnosis command that allows you to test various circuits
and subsystems in the programmer, verifying proper operation or
isolating possible problem areas.
Serial Set A method of set programming in which the devices of the set are
programmed one at a time instead of all at once.
Serial Test Vector
Application
The process of applying test vectors in a serial fashion, one input at a
time.
Serial Vector Test A device test that applies test vector input states serially, starting with pin
one and stepping through the remaining pins. This test is a diagnostic
tool designed to help debug and classify test vector failures. Specifically,
this test is designed to isolate test vectors that are sequence dependent.
Set Programming A type of programming where a large data file is partitioned and
programmed into multiple memory devices.
SIMM An Acronym for Single Inline Memory Module, a type of device package.
A rectangular device with leads on one long edge.
