options for drive strength, bus maintenance (weak pull-up, weak pull-down, or a bus-keeper latch) and open drain.
Other single-ended standards supported include SSTL and HSTL. Differential standards supported include LVDS,
BLVDS, LVPECL, RSDS, differential SSTL and differential HSTL. Tables 2-13 and 2-14 show the I/O standards
(together with their supply and reference voltages) supported by the LatticeECP/EC devices. For further informa-
tion on utilizing the sysIO buffer to support a variety of standards please see the details of additional technical infor-
mation at the end of this data sheet.
