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

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

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.

Programming Support

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 PLACE 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,

Logic

Devices

and

numerous

others.
