XC4000XL: some devices have a higher VCC pin to GND pin ratio

Description

Keywords: xc4000xl, pinouts, VCC, GND

Urgency: standard

General Description: In some of the XC4000XL devices, there
are more GND pins than VCC. However, in some of the other
devices (for example, 4085XL), there are more VCC pins than
GND pins.

解决方案

In some of the XC4000XL devices, additional VCC pins have
been included to facilitate future migration to XC4000XV
devices, which require additional VCC pins for IO and/or
core.
