Figure 2-38. LatticeECP3 Banks
LatticeECP3 devices contain two types of sysI/O buffer pairs.
1. Top (Bank 0 and Bank 1) and Bottom sysIO Buffer Pairs (Single-Ended Outputs Only)
The sysI/O 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. Only the top edge buffers have a programmable PCI clamp.

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 top and bottom sides are ideal for ADDR/CMD signals of DDR3, general purpose I/O, PCI, TR-LVDS (tran-
sition reduced LVDS) or LVDS inputs. 

The I/O pins located on the top and bottom sides of the device are fully hot socketable.
