General Description
The PEEL™22CV10A is a Programmable Electrically Eras-
able Logic (PEEL™) device providing an attractive alterna-
tive to ordinary PLDs. The PEEL™22CV10A offers the
performance, flexibility, ease of design and production
practicality needed by logic designers today. The
PEEL™22CV10A is available in 24-pin DIP, SOIC, TSSOP
and 28-pin PLCC packages (see Figure 1), with speeds
ranging from 7ns to 25ns and with power consumption as
low as 30mA. EE-reprogrammability provides the conve-
nience of instant reprogramming for development and a
reusable production inventory, minimizing the impact of
programming changes or errors. EE-reprogrammability
s Architectural Flexibility
- 132 product term X 44 input AND array
- Up to 22 inputs and 10 outputs
- Up to 12 configurations per macrocell
- Synchronous preset, asynchronous clear
- Independent output enables
- 24-pin DIP/SOIC/TSSOP and 28-pin PLCC
s Application Versatility
- Replaces random logic
- Pin and JEDEC compatible with 22V10
- Enhanced Architecture fits more logic
than ordinary PLDs
also improves factory testability, thus ensuring the highest
quality possible. The PEEL™22CV10A is JEDEC file com-
patible with standard 22V10 PLDs. Eight additional configu-
rations per macrocell (a total of 12) are also available by
using the “+” software/programming option (i.e.,
22CV10A+). The additional macrocell configurations allow
more logic to be put into every design. Programming and
development support for the PEEL™22CV10A are pro-
vided by popular third-party programmers and develop-
ment software. ICT also offers free PLACE development
software.

PEELTM 22CV10A
enable term will permanently enable the output buffer and
yield a dedicated output. Conversely, if every connection is
intact, the enable term will always be logically false and the
I/O will function as a dedicated input.
Input/Feedback Select
When configuring an I/O macrocell to implement a regis-
tered function (configurations 1 and 2 in Figure 5), the Q
output of the flip-flop drives the feedback term. When con-
figuring an I/O macrocell to implement a combinatorial
function (configurations 3 and 4 in Figure 5), the feedback
signal is taken from the I/O pin. In this case, the pin can be
used as a dedicated input or a bi-directional I/O. (Refer
also to Table 1.)
Additional Macro Cell Configurations
Besides the standard four-configuration macrocell shown in
Figure 5, each PEEL™22CV10A provides an additional
eight configurations that can be used to increase design
flexibility. The configurations are the same as provided by
the PEEL™18CV8 and PEEL™22CV10AZ. However, to
maintain JEDEC file compatibility with standard 22V10
PLDs the additional configurations can only be utilized by
specifying the PEEL™22CV10A+ for logic assembly and
programming. To reference these additional configurations
please refer to the PEEL™22CV10A+ specifications at the
end of this data sheet.
Design Security
The PEEL™22CV10A provides a special EEPROM secu-
rity bit that prevents unauthorized reading or copying of
designs programmed into the device. The security bit is set
by the PLD programmer, either at the conclusion of the pro-
gramming cycle or as a separate step after the device has
been programmed. Once the security bit is set, it is impos-
sible 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 24-bit code to be pro-
grammed into the PEEL™22CV10A if the
PEEL™22CV10A+ 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.
