PALLV22V10 and PALLV22V10Z Families

BLOCK DIAGRAM

FUNCTIONAL DESCRIPTION

The PALLV22V10 is the low-voltage version of the PALCE22V10. It has all the architectural features

of the PALCE22V10.

The PALLV2210Z is the low-voltage, zero-power version of the PALCE22V10. It has all the

architectural features of the PALCE22V10. In addition, the PALLV22V10Z has zero standby power

and an unused product term disable feature.

The PALLV22V10 allows the systems engineer to implement a design on-chip by programming EE

cells to configure AND and OR gates within the device, according to the desired logic function.

Complex interconnections between gates, which previously required time-consuming layout, are

lifted from the PC board and placed on silicon, where they can be easily modified during

prototyping or production.

Product terms with all connections opened assume the logical HIGH state; product terms

connected to both true and complement of any single input assume the logical LOW state.

The PALLV22V10 has 12 inputs and 10 I/O macrocells. The macrocell (Figure 1) 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

to ground (0) through a programmable bit, selecting the “0” path through the multiplexer. Erasing

The device is produced with a EE cell link at each input to the AND gate array, and connections

may be selectively removed by applying appropriate voltages to the circuit. Utilizing an easily-

implemented programming algorithm, these products can be rapidly programmed to any

customized pattern.
