  Yes, you can control the TRIM output directly by writing values to the DAC register using the I2C port. To do this you must set the TRIM output in the I2C control mode for profile 0. This can be done with the POWR1220AT8 or the POWR6AT6 device. The ...

  Description: No, the impedance of HVOUT (in the open drain mode) and OUT port is not equal. The design for both the ports is different since HVOUT is designed for higher voltages (10V/12V) and OUT is designed for lower voltages(5.5V). For example ...

  The Input only IO, do not need to be erased and reprogrammed to be bi-di IO. Only output only IO needs it.

  If user's design is using 50 ohm PCB trace and cable impedances, user can set the LatticeXP2 IO output type to LVDS and this will produce 400mv peak signal swing at the receiver's 100 ohm termination with proper common mode output voltage. The ...
