HEX file

A human-readable ASCII file that represents any binary data. Each byte in

 

the binary pattern is represented by two HEX characters (0-9, A-F) so that

 

any of the 256 possible bytes, which include both control and unprintable

 

characters, may be printed. The HEX file may also contain address or

 

checksum information. The pattern represented by the HEX file may be

 

represented by a binary file or any of the HEX file formats – any file format

 

may contain any pattern. The names of the HEX file formats (Intel, Motorola,

 

Tektronix, etc.) indicate who standardized its format and does not indicate

 

anything about the pattern or the device the pattern is intended for.

I/O

Input/ Output.

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
