Mixed Voltage Support in a Bank
The LatticeECP/EC and LatticeXP sysIO buffer is connected to three parallel ratioed input buffers. These three par-
allel buffers are connected to V
as fixed thresholds for 3.3V (V
assigned on a pin-by-pin basis, rather than tracking it with V
ratioed inputs and is independent of the bank V
have 1.2V and 3.3V ratioed input buffers with fixed thresholds, as well as 2.5V ratioed inputs with tracking thresh-
olds.
Prior to device configuration, the ratioed input thresholds always track the bank V
after configuration. Output standards within a bank are always set by V
that the user can mix in the same bank.
