Figure 2-34. LatticeECP2 Banks
LatticeECP2 devices contain two types of sysIO buffer pairs.
1. Top (Bank 0 and Bank 1) sysIO Buffer Pairs (Single-Ended Outputs Only)
2. Bottom (Bank 4 and Bank 5) sysIO Buffer Pairs (Single-Ended Outputs Only)
The sysIO buffer pairs in the top banks of the device consist of two single-ended output drivers and two sets of
single-ended input buffers (both ratioed and referenced). One of the referenced input buffers can also be con-
figured 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 differential input buffer and the comp (complementary) pad is associated with the negative side of
the differential input buffer.
The sysIO buffer pairs in the bottom banks of the device consist of two single-ended output drivers and two
sets of single-ended input buffers (both ratioed and referenced). One of the referenced input buffers 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 differential input buffer and the comp (complementary) pad is associated with the negative side of
the differential input buffer.
Only the I/Os on bottom banks have programmable PCI clamps.
