Voltage of bank 3 on MityARM 1810F

Added by Emmett Bradford over 9 years ago

I started my FPGA code using fpga/vhdl/MityDSP_L138.ucf
I want to add to the design io_gp8(15 downto 8).
These lines are commented out in MityDSP_L138.ucf but the IO is 1.8V.
NET "io_gp8<15>" LOC = "T1" | IOSTANDARD = LVCMOS18;

1.8V conflicts with:
NET "o_int<0>" LOC = "K6" | IOSTANDARD = LVCMOS33;
NET "o_int<1>" LOC = "F2" | IOSTANDARD = LVCMOS33;

What is the IO voltage of bank 3?
If I could have a schematic, I could look it up there!

Are these lines truly connect to the AM1808 as implied in the UCF?

No that is a typo in the UCF file. The voltage is really 1.8V.

Those lines in the UCF should be as shown below. I thought we had corrected that in the BSP packages, looks like the errors are still there. Sorry Emmett.

NET "o_int<0>" LOC = "K6" |IOSTANDARD = LVCMOS18;
NET "o_int<1>" LOC = "F2" |IOSTANDARD = LVCMOS18;

For modules with an FPGA included, the FPGA bank voltages are:

VCCO_0 = externally set
VCCO_1 = externally set
VCCO_2 = 3.3 V
VCCO_3 = 1.8 V
VCCINT = 1.2 V
VCCAUX = 3.3 V

For modules with an FPGA included, the OMAP-L138 / AM1808:

Power Group A = 3.3 V
Power Group B = 3.3 V
Power Group C = 1.8 V

Thanks for the quick reply!
