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.
7.
Programming/Erasing
Programming/erasing is performed using standard PLD programmers. See CMOS PLD Pro-
gramming Hardware and Software Support for information on software/programming.

Input and I/O Pull-ups
All ATF16V8B family members have internal input and I/O pull-up resistors. Therefore, when-
ever inputs or I/Os are not being driven externally, they will float to V
CC. 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).

Functional Logic Diagram Description
The Logic Option and Functional Diagrams describe the ATF16V8B architecture. Eight config-
urable macrocells can be configured as a registered output, combinatorial I/O, combinatorial
output, or dedicated input.
The ATF16V8B can be configured in one of three different modes. Each mode makes the
ATF16V8B look like a different device. Most PLD compilers can choose the right mode automat-
ically. The user can also force the selection by supplying the compiler with a mode selection.
The determining factors would be the usage of register versus combinatorial outputs and dedi-
cated outputs versus outputs with output enable control.
The ATF16V8B universal architecture can be programmed to emulate many 20-pin PAL
devices. These architectural subsets can be found in each of the configuration modes described
