ATF16V8B

ATF16V8B Complex Mode

PAL Device Emulation/PAL Replacement

Combinatorial applications with an OE requirement will

make the compiler select this mode. The following devices

can be emulated using this mode:

In the Complex Mode, combinatorial output and I/O func-

tions are possible. Pins 1 and 11 are regular inputs to the

array. Pins 13 through 18 have pin feedback paths back to

the AND-array, which makes full I/O capability possible.

Pins 12 and 19 (outermost macrocells) are outputs only.

They do not have input capability. In this mode, each

macrocell has seven product terms going to the sum term

and one product term enabling the output.

ATF16V8B Simple Mode

PAL Device Emulation / PAL Replacement

The compiler selects this mode when all outputs are com-

binatorial without OE control. The following simple PALs

can be emulated using this mode:

In the Simple Mode, 8 product terms are allocated to the

sum term. Pins 15 and 16 (center macrocells) are perma-

nently configured as combinatorial outputs. Other macro-

cells can be either inputs or combinatorial outputs with pin

feedback to the AND-array. Pins 1 and 11 are regular in-

puts.
