PEEL22LV10AZ-25

CMOS Programmable Electrically Erasable Logic Device

Anachip Corporation 

Schmitt Trigger Inputs

The PEEL™22LV10AZ has Schmitt trigger input buffers on all

inputs, including the clock. Schmitt trigger inputs allow direct

input of slow signals such as biomedical and sine waves or

clocks. They are also useful in cleaning up noisy signals. This

makes the PEEL™22LV10AZ especially desirable in portable

applications where the environment is less predictable.

Design Security

The PEEL™22LV10AZ 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.

Programming Support

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

ing 24 pin PLD designs to the PEEL™22LV10AZ, without the

need for redesign. Anachip also offers (for free) its proprietary

WinPLACE software, an easy-to-use entry level PC-based soft-

ware development system.

Programming support includes all the popular third party pro-

grammers such as BP Microsystems, System General, Logical

Devices, and numerous others.

Signature Word

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

grammed into the PEEL™22LV10AZ if the PEEL™22LV10AZ+

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 iden-

tify the pattern programmed into the device or to record the

design revision, etc.
