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.

Additional Macrocell Configurations
Besides the standard four-configuration macrocells, each
PEEL™22CV10A provides an additional eight configura-
tions (twelve total) that can be used to increase design flex-
ibility
(see Figure 6 and Table 2). For logic assembly of all twelve
configurations, specify PEEL™22CV10A+. Also, select the
PEEL™22CV10A+ for programming.
