ENDURANCE CHARACTERISTICS
The PALCE20V8 is manufactured using Vantis’ advanced electrically-erasable (EE) CMOS process.
This technology uses an EE cell to replace the fuse link used in bipolar parts. As a result, the
device can be erased and reprogrammed—a feature which allows 100% testing at the factory.
ROBUSTNESS FEATURES
The PALCE20V8X-X/5 have some unique features that make them extremely robust, especially
when operating in high-speed design environments. Pull-up resistors on inputs and I/O pins
cause unconnected pins to default to a known state. Input clamping circuitry limits negative
overshoot, eliminating the possibility of false clocking caused by subsequent ringing. A special
noise filter makes the programming circuitry completely insensitive to any positive overshoot
that has a pulse width of less than about 100 ns for the /5 versions.
