ATF22V10B-10JC ATMEL [ATMEL Corporation], ATF22V10B-10JC Datasheet - Page 6

• Manufacturer Part Number: ATF22V10B-10JC
• Description: High- Performance EE PLD
• Manufacturer: ATMEL [ATMEL Corporation]

Electronic Signature Word
There are 64 bits of programmable memory that are always
available to the user, even if the device is secured. These
bits can be used for user-specific data.
Programming/Erasing
Programming/erasing is performed using standard PLD
programmers. See CMOS PLD Programming Hardware
and Software Suppor t for information on software/program-
ming.

Input and I/O Pull-Ups
All ATF22V10B family members have internal input and I/O
pull-up resistors. Therefore, whenever inputs or I/Os are
not being driven externally, they will float to V
ensures that all logic array inputs are at known states.
These are relatively weak active pull-ups that can easily be
overdriven by TTL-compatible drivers (see input and I/O
diagrams below).
