XC4000XL: some devices have a higher VCC pin to GND pin ratio
説明
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.
ソリューション
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.
