This is a document about Altera Cyclone III device family pin connection guidelines
This document provides preliminary pin connection recommendations for the Cyclone III device family. It details specific voltage requirements and grounding strategies for various supply pins, including VCCINT, VCCIO, and analog supplies like VCCAII.
The guide also covers dedicated configuration and JTAG pins such as DCLK, DATA[0], MSEL, nCE, and CONFIG. It outlines connection rules based on different configuration modes (PS, FPP, AS, AP) and provides instructions for handling unused or no-connect pins.
| VCCINT Voltage Requirement | 1.2V supply |
|---|---|
| VCCAII Voltage Requirement | 1.2V |
| RDN Pin Connection | Designated RDN pin or GND |
All VCCINT pins must be connected to a 1.2V supply.
If not required, the RUP pin is a regular I/O pin, while the RDN pin should be connected to GND.
Unused CONFIG pins must be connected directly or through a 10-kOhm resistor to VCCIO.
