The signature word feature allows a 64-bit code to be
programmed into the PEEL18LV8Z 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 programmed into the device or to
record the design revision, etc.

Design Security
The PEEL18LV8Z provides a special EEPROM security bit
that prevents unauthorized reading or copying of designs
programmed into the device. The PLD programmer sets
the security bit, either at the conclusion of the programming
cycle or as a separate step, after the device has been
Anachip's JEDEC file translator allows easy conversion of
existing 20 pin PLD designs to the PEEL18LV8Z, without
the need for redesign. Anachip also offers (for free) its
proprietary WinPLACE software, an easy-to-use entry level
PC-based software development system.
Programming support includes all the popular third party
programmers such as BP Microsystems, System General,
