FUNCTIONAL DESCRIPTION
The ABT22V10A allows the systems engineer to implement the
design on-chip, by opening fuse links to configure AND and OR
gates within the device, according to the desired logic function.
Product terms with all fuses opened assume the logical HIGH state;
product terms connected to both True and Complement of any
single input assume the logical LOW state.
The ABT22V10A has 12 inputs and 10 I/O Macro Cells (Figure 1).
The Macro Cell allows one of four potential output configurations,
registered output or combinatorial I/O, Active-HIGH or Active-LOW
(see Figure 2). The configuration choice is made according to the
user’s design specification and corresponding programming of the
configuration bits S0 –S1. Multiplexer controls are connected to
ground (0) through a programmable fuse link, selecting the “0” path
through the multiplexer. Programming the fuse disconnects the
control line from GND and it floats to VCC (1), selecting the “1” path.
