Hot Socketing
LatticeXP2 devices have been carefully designed to ensure predictable behavior during power-up and power-
down. Power supplies can be sequenced in any order. During power-up and power-down sequences, the I/Os
remain in tri-state until the power supply voltage is high enough to ensure reliable operation. In addition, leakage
into I/O pins is controlled to within specified limits. This allows for easy integration with the rest of the system.
These capabilities make the LatticeXP2 ideal for many multiple power supply and hot-swap applications.
IEEE 1149.1-Compliant Boundary Scan Testability
All LatticeXP2 devices have boundary scan cells that are accessed through an IEEE 1149.1 compliant Test Access
Port (TAP). This allows functional testing of the circuit board, on which the device is mounted, through a serial scan
path that can access all critical logic nodes. Internal registers are linked internally, allowing test data to be shifted in

1. Emulated with external resistors.
2. On the left and right edges, LVDS outputs are supported with a dedicated differential output driver on 50% of the I/Os. This
solution does not require external resistors at the driver.
