Example 5— MAX® 10 (Single Supply) FPGA
Note: Altera recommends that you create a Quartus® Prime design, enter your device I/O assignments, and compile the design. The Quartus® Prime software checks your pin connections according to I/O assignment and placement rules. The rules differ from one device to another based on device density, package, I/O assignments, voltage assignments, and other factors that are not fully described in this document or the device user guides.
Power Pin Name | Regulator Count | Voltage Level (V) | Supply Tolerance | Power Source | Regulator Sharing | Notes |
---|---|---|---|---|---|---|
VCC_ONE | 1 | 3.0/3.3 | ±5% | Switcher 5 | Share | Both VCCA and VCC_ONE must share a single power source using proper isolation filter. |
VCCA | Isolate | |||||
VCCIO1B | 2 | 3.0/3.3 | ±5% | Switcher5 | Share | You have the option to share VCCIO1B and VCCIO[2..8] when these pins are powered up at 3.0V/3.3V. |
VCCIO[2..8] | ||||||
VCCIO1A | Isolate | You have the option to share VCCIO1A with VCCIO1B and VCCIO[2..8] using proper isolation filter. |
Note:
- Use the EPE (Early Power Estimation) tool to assist in determining the power required for your specific design.
- Each board design requires its own power analysis to determine the required power regulators needed to satisfy the specific board design requirements. An example block diagram using the MAX® 10 FPGA device is provided in the following figure.
- Refer to the MAX® 10 FPGA Configuration User Guide for maximum ramp rate requirement.

5 When using a switcher to supply these voltages, the switcher must be a low noise switcher as defined in Note 9 of the Notes to the MAX® 10 FPGA Pin Connection Guidelines.
