Electronic Signature Word

Input and I/O Pull-Ups

There are 64 bits of programmable memory that are al-

ways available to the user, even if the device is secured.

These bits can be used for user-specific data.

All ATF16V8B 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 . This en-

sures 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).

Programming/Erasing

Programming/erasing is performed using standard PLD

programmers. See CMOS PLD Programming Hardware &

Software Support for information on software/program-

ming.

Functional Logic Diagram Description

The Logic Option and Functional Diagrams describe the

ATF16V8B architecture. Eight configurable macrocells

can be configured as a registered output, combinatorial

I/O, combinatorial output, or dedicated input.

architectural subsets can be found in each of the configu-

ration modes described in the following pages. The user

can download the listed subset device JEDEC program-

ming file to the PLD programmer, and the ATF16V8B can

be configured to act like the chosen device. Check with

your programmer manufacturer for this capability.

The ATF16V8B can be configured in one of three different

modes. Each mode makes the ATF16V8B look like a dif-

ferent device. Most PLD compilers can choose the right

mode automatically. The user can also force the selection

by supplying the compiler with a mode selection. The de-

termining factors would be the usage of register versus

combinatorial outputs and dedicated outputs versus out-

puts with output enable control.

Unused product terms are automatically disabled by the

compiler to decrease power consumption. A Security

Fuse, when programmed, protects the content of the

ATF16V8B. Eight bytes (64 fuses) of User Signature are

accessible to the user for purposes such as storing project

name, part number, revision, or date. The User Signature

is accessible regardless of the state of the Security Fuse.

The ATF16V8B universal architecture can be pro-

grammed to emulate many 20-pin PAL devices. These
