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.
