MAX 3000A Programmable Logic Device Family Data Sheet

Programmable Interconnect Array

Logic is routed between LABs on the PIA. This global bus is a

programmable path that connects any signal source to any destination on

the device. All MAX 3000A dedicated inputs, I/O pins, and macrocell

outputs feed the PIA, which makes the signals available throughout the

entire device. Only the signals required by each LAB are actually routed

from the PIA into the LAB. Figure 5 shows how the PIA signals are routed

into the LAB. An EEPROM cell controls one input to a 2-input AND gate,

which selects a PIA signal to drive into the LAB.

Figure 5. MAX 3000A PIA Routing

While the routing delays of channel-based routing schemes in masked or

field-programmable gate arrays (FPGAs) are cumulative, variable, and

path-dependent, the MAX 3000A PIA has a predictable delay. The PIA

makes a design’s timing performance easy to predict.

I/O Control Blocks

The I/O control block allows each I/O pin to be individually configured

for input, output, or bidirectional operation. All I/O pins have a tri-state

buffer that is individually controlled by one of the global output enable

signals or directly connected to ground or VCC. Figure 6 shows the I/O

control block for MAX 3000A devices. The I/O control block has

six global output enable signals that are driven by the true or complement

of two output enable signals, a subset of the I/O pins, or a subset of the

I/O macrocells.
