HEX file | A |
| the binary pattern is represented by two HEX characters |
| 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 |
| 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 |
| 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 |
