  The user can power up the Lattice MachXO2 part using only the VCC core and one VCCIO bank. There are, however, a few constraints: As per the "Typical I/O Behavior During Power-up" section of the MachXO2 Family Data Sheet, the user needs to pick ...

  Solution: In order to assign a 3.3V inputs to a 1.5 V bank on the top side of a LatticeECP3 device (Bank 0 and Bank1), turn off the PCICLAMP in Spreadsheet view for the respective bank. By default, the PCICLAMP is ON for all the banks and hence, ...

  Whether an I/O pad is hot-socketable or not is determined by the location of the pad instead of the bank where the pad is included. All general purpose I/O pads located on the top and bottom sides of LatticeECP3 devices are hot-socketable.These are ...

  For iCEcube2 compatible devices (LP/HX/LM/Ultra/UltraLite/UltraPlus), the user needs to use the SB_IO primitive and override the IO_STANDARD parameter to SB_LVDS_INPUT as shown in the rudimentary example below: SB_IO SB_IO_inst ( ...

  Description: Two 5V support options, “PCI_5V” and “LVTTL_5V” were added to the supporting I/O type constraint list for the ispMACH™ 4000 device families. Since the LVTTL I/O type's maximum VIH is 3.6V, you must use the LVTTL_5V I/O type to support 5V ...
