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 Support 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 VCC. This

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).
