Cyclone III
Devices
Thermal resistance values for Cyclone III devices are provided for a board
meeting JEDEC specifications and for a typical board. The JEDEC board
specifications require two signals and two power/ground planes and are
available at www.jedec.org. The values are described in Tables 1
through 4.
Table 1. Thermal Resistance Values for Cyclone III Devices
Value
Description
θJA (C/W) Still Air
Junction-to-ambient thermal resistance (θJA) with no airflow when a heat sink
is not being used.
θJA (C/W) 100 ft./minute
Junction-to-ambient thermal resistance with 100 ft./minute airflow when a
heat sink is not being used.
θJA (C/W) 200 ft./minute
Junction-to-ambient thermal resistance with 200 ft./minute airflow when a
heat sink is not being used.
θJA (C/W) 400 ft./minute
Junction-to-ambient thermal resistance with 400 ft./minute airflow when a
heat sink is not being used.
θJC (C/W)
Junction-to-case thermal resistance (θJC) for device.
θJB (C/W)
Junction-to-board thermal resistance (θJB) for specific board being used.
Table 2 provides θ JA (junction-to-ambient thermal resistance) values and
θJC (junction-to-case thermal resistance) values for Cyclone III devices on
a board meeting JEDEC specifications for thermal resistance calculation.
