OUTPUT POLARITY

Each macrocell can be configured to implement Active-High

or Active-Low logic. Programmable polarity eliminates the

need for external inverters.

OUTPUT ENABLE

The output of each I/O macrocell can be enabled or disabled

under the control a programmable output enable product term.

The output signal is propagated to the I/O pin when the logical

conditions programmed on the output enable term are satisfied.

Otherwise, the output buffer is driven to the high-impedance

state.

The output enable term allows the I/O pin to function as a ded-

icated input, dedicated output, or bidirectional I/O. When every

connection is unprogrammed, the output enable product term

permanently enables the output buffer and yields a dedicated

output. If every connection is programmed, the enable term is

logically low and the I/O functions as a dedicated input.

REGISTER FEEDBACK

The feedback signal to the AND array is taken from the Q output

when the I/O macrocell implements a registered function

(C2 = 0, C1 = 0).

BIDIRECTIONAL I/O

The feedback signal is taken from the I/O pin when the macro-

cell implements a combinatorial function (C1 = 1) or a regis-

tered function (C2 = 1, C1 = 0). In this case, the pin can be used

as a dedicated input, a dedicated output, or a bidirectional I/O.

POWER-ON RESET

To ease system initialization, all D flip-flops will power-up to

a reset condition and the Q output will be low. The actual output

of the UT22VP10 will depend on the programmed output po-

larity. The reset delay time is 5µs maximum. See the Power-up

Reset section for a more descriptive list of POR requirements.

ANTI-FUSE SECURITY

The UT22VP10 provides a security bit that prevents unautho-

rized reading or copying of designs programmed into the de-

vice. The security bit is set by the PLD programmer at the con-

clusion of the programming cycle. Once the security bit is set

it is no longer possible to verify (read) or program the

UT22VP10. NOTE: UTMC does not recommend using the

UT22VP10 unless the security fuse has been programmed.

The security bit must be blown to ensure proper function-

ality of the UT22VP10.
