Power Supply Sharing Guidelines

Table 6.  Power Supply Sharing Guidelines for Intel® Cyclone® 10 LP DevicesExample Requiring 2 Power Regulators
Power Pin Name Regulator Count Voltage Level (V) Supply Tolerance Power Source Regulator Switching Notes
VCCINT 1 1.0/1.2 ± 30 mV/± 50 mV Switcher (*) Share You have the option to share VCCD_PLL with VCCINT using a proper isolation filter. With proper isolation filter, limit the VCCD_PLL power supply to ±3% maximum ripple voltage. Depending on the regulator capabilities, this supply may be shared with multiple Intel® Cyclone® 10 LP devices. Use the Early Power Estimation (EPE) tool within the Intel® Quartus® Prime software to assist in determining the power required for your specific design.
VCCD_PLL Isolate
VCCIO 2 Varies ± 5 % Linear or Switcher (*) Share if 2.5 V If VCCIO requires 2.5 V, you have the option to share VCCA with VCCIO using a proper isolation filter. However, for any other VCCIO voltage, you will require a 2.5 V regulator for VCCA. Use the Early Power Estimation (EPE) tool within the Intel® Quartus® Prime software to assist in determining the power required for your specific design.
VCCA 2.5 Isolate You have the option to share VCCA with VCCIO using a proper isolation filter. With proper isolation filter, limit the VCCA power supply to ±3% maximum ripple voltage. Depending on the regulator capabilities, this supply may be shared with multiple Intel® Cyclone® 10 LP devices. Use the Early Power Estimation (EPE) tool within the Intel® Quartus® Prime software 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.

Figure 1. Example Power Supply Sharing Guidelines for Intel® Cyclone® 10 LP Devices
Note:
  1. When using a switcher power supply for VCCA, limit this supply to ±3% maximum ripple voltage. When using a switcher power supply for VCCD_PLL, limit this supply to ±3% maximum ripple voltage.
  2. Connect VCCIO pins on banks 4, 5, 6, 7, and 8 to 1.2 V/ 1.5 V/ 1.8 V/ 2.5 V/ 3.0 V/ 3.3 V supplies, depending on the I/O standard connected to the specified bank.
  3. There are two variants of Intel® Cyclone® 10 LP devices; one powered with core voltage VCCINT 1.0 V, and another powered with core voltage VCCINT 1.2 V. Each variant has different ordering codes.
