Design Security

The PEEL™18CV8Z provides a special EEPROM security bit

that prevents unauthorized reading or copying of designs pro-

grammed into the device. The security bit is set by the PLD pro-

grammer, either at the conclusion of the programming cycle or as a

separate step, after the device has been programmed. Once the

security bit is set it is impossible to verify (read) or program the

PEEL™ until the entire device has first been erased with the

bulk-erase function.

Signature Word

The signature word feature allows a 64-bit code to be pro-

grammed into the PEEL™18CV8Z if the software option is used.

The code can be read back even after the security bit has been set.

The signature word can be used to identify the pattern pro-

grammed into the device or to record the design revision, etc.

Programming Support

Anachip’s JEDEC file translator allows easy conversion of exist-

ing 20 pin PLD designs to the PEEL™18CV8Z, without the need

for redesign. Anachip also offers (for free) its proprietary Win-

PLACE software, an easy-to-use entry level PC-based software

development system.

Programming support includes all the popular third party pro-

grammers such as BP Microsystems, System General, Logical

Devices, and numerous others.
