Table 8-1. Supported sysIO Standards
sysIO Banking Scheme
LatticeECP/EC and LatticeXP devices have eight programmable sysIO banks, two per side. Each sysIO bank has
a V
fer pair consists of two single-ended output drivers and two sets of single-ended input buffers (both ratioed and ref-
erenced). The left and right side sysIO buffer pair along with the two single-ended output and input drivers will also
have a differential driver. The referenced input buffer can also be configured as a differential input. The two pads in
the pair are described as “true” and “comp”, where the true pad is associated with the positive side of the differen-
tial input buffer and the comp (complementary) pad is associated with the negative side of the differential input buf-
fer. Figure 8-1 shows the eight banks and their associated supplies.
