Pin Information Summary (Cont.)
Lattice Semiconductor
Logic Signal Connections
Package pinout information can be found under “Data Sheets” on the LatticeXP2 product page of the Lattice web-
site a www.latticesemi.com/products/fpga/xp2 and in the Lattice ispLEVER software.
Thermal Management
Thermal management is recommended as part of any sound FPGA design methodology. To assess the thermal
characteristics of a system, Lattice specifies a maximum allowable junction temperature in all device data sheets.
Designers must complete a thermal analysis of their specific design to ensure that the device and package do not
exceed the junction temperature limits. Refer to the Lattice
package specific thermal values.
