JEDEC Joint Electron Device Engineering Council (pronounced JED‟eck). A group
organized by the IEEE (Institute of Electrical and Electronics Engineers) that
has defined a standard file format for PLDs.
JEDEC file A file conforming to a standard format that specifies the configuration and
testing procedure for a PLD. The file is in a human-readable ASCII format
and consists of fields that start with a letter and end with an asterisk. Fields
specify the pattern to program into the part, whether to secure the device, a
set of test vectors to perform a functional test, and checksums to verify the
integrity of the file.
LCC Leadless Chip Carrier. A square ceramic package that has no leads; Instead it
has metal areas that are surface-mount soldered to the target circuit. This
package is usually used only for military and aerospace applications.
Available up to 84 pins.
Memory device A Device that contains an array of storage locations. The device has a set of
inputs, called address, which specify which location in the array is being
accessed. A set of input/output pins produce the stored number (pattern)
when the device is read, and accept a new value when the device is written or
programmed. Additionally, there are one or more input pins that select the
operating move (read, write, standby, etc.). Memory devices may be
classified by whether they are volatile or nonvolatile, and whether they may
be erased. The memory‟s organization refers to its word width and the
number of words in the device.
Microcontroller A device that contains a central processing unit (CPU), memory, and I/O
ports on a single IC. Microcontrollers that contain any form of nonvolatile
memory may be programmed on a device programmer. When connected to a
power supply and external crystal, many of these devices form a complete
microcomputer.
Non-Volatile The Characteristic of a memory that does not lose its contents when its
power is removed. Non-volatile memory is useful in microcomputer circuits
because it can provide instructions for a CPU as soon as the power is applied,
