5772 - Where can I find the Package Thermal Resistance value of a legacy device or a device that is not specified on the Thermal Management Technical Note (FPGA-TN-02044)?
If not specified on the "Device/Package Thermal Resistance" section you can refer to the generic table, Table 3.1. Package Thermal Resistance. This section specifies the generic thermal resistance for legacy Generic Array Logic (GAL), CPLD, FPGA and Expanded Programmable Logic Device (XPLD) devices.
