A.2.1.2. Power Sequence
The Intel® Stratix® 10 DX FPGA device requires proper power up and power down sequences.
Group 1 | Group 2 | Group 3 |
---|---|---|
VCCL/VCC (0.89) VCCERAM (0.9) VCCPLLDIG_SDM (0.9) VCCRT_GXP (0.9) VCCRT_GXE (0.9) VCCRTPLL_GXE (0.9) VCCFUSE_GXP (0.9) |
VCCH_GXE (1.1) VCCH_GXP (1.8) VCCADC (1.8) VCCPLL_SDM (1.8) VCCAPLL (1.8) VCCIO (2.5) VCCIO (1.8) |
VCCIO (1.2, 1.25, 1.35, 1.5, 1.8) VCCFUSEWR_SDM (2.4) VCCN_SDM (1.8) VCCIO3 (1.5, 1.8, 2.5, 3.0) |
- Required power up sequence: Group 1 > Group 2 > Group 3
- Required power down sequence: Group 3 > Group 2 > Group 1
- I/O pins are tri-stated during power-up or down sequence when the proper power sequence is followed. I/O pins should not be driven externally during this time or excess I/O pin current can result.
- Power supplies in each group can be ramped up in any order.
- The total power supply ramp-down time must not exceed 100 ms.
- Ramp-up the last power supply of Group 1 to 90% (0.72) before ramping up the Group 2 supplies. Ramp up the last power supply of Group 2 to 90% (1.62V) before ramping up the Group 3 supplies.
- VCCBAT_SDM can be powered up anytime.
- To use CvP/autonomous hard IP, the total time must be within 10 ms, from the first power supply ramp-up to the last power supply ramp-up.
Note: The POR delay time in Intel® Stratix® 10 DX FPGA is always within 2ms.
- VCCL and VCC should be tied together at customer board.
- VCCPLL_HPS and VCCPLL_SDM should be tied together at customer board.
- VCCPLLDIG_SDM and VCCERAM should be tied together at customer board with a filter.
- VCCADC and VCCA should be tied together at customer board with or without a filter.
- VCCERT, VCCERT_PLL and VCCERAM should be tied together at customer board with or without a filter and should ramp up together for better current control.
- Noise mask specifications must be met.
- Use of an LC Filter is proposed to enable sourcing VCCERT, VCCERT_PLL from VCCERAM.
- VCCN_SDM has to stay in Group 3. It cannot be moved to Group 2 or merged with any Group 2 regulator.
- VCCFUSE_GXP is always connected to VCCERAM on customer board. For only internal testing purposes, VCCFUSE_GXP is connected to VCCR.
- All power rails must ramp up monotonically.
- All power rails must ramp up to full rail in Tramp specified in the Intel® Stratix® 10 Device Datasheet.
- Ensure (VCCIO - VCCPT) is less than 1.92 to avoid damage to the device
- Hot socket is not supported in Intel® Stratix® 10 DX FPGA.
