This document is a technical document released by Altera Corporation about Cyclone® III Device Family Pin Connection Guidelines
This document serves as a preliminary guide for determining pin connections for Altera Cyclone III programmable logic devices. It is not a specification and should be verified against the official datasheet before use in any design. The guidelines cover power supply requirements, input reference voltages, and ground connections.
| VCCINT Supply Voltage | 1.2 V |
|---|---|
| VCCIO Supported Voltages | 1.2 V, 1.5V, 1.8V, 2.5 V, 3.0V, 3.3V |
| VCCBAT Operating Range | 1.2 to 3.3 V |
No, the guidelines are considered preliminary and should only be used as a recommendation, not as a specification.
No, VCCINT pins must be connected to a 1.2 V supply.
