ADSP-21262
ENVIRONMENTAL CONDITIONS
The ADSP-21262 processor is rated for performance over the
commercial temperature range, T
AMB
= 0°C to 70°C.
THERMAL CHARACTERISTICS
Table 32
and
Table 33
airflow measurements comply with
JEDEC standards JESD51-2 and JESD51-6 and the junction-to-
board measurement complies with JESD51-8. The junction-to-
case measurement complies with MIL-STD-883. All measure-
ments use a 2S2P JEDEC test board.
To determine the Junction Temperature of the device while on
the application PCB, use:
where:
T
J
= Junction temperature
°
C
T
CASE
= Case temperature (
°
C) measured at the top center of the
package
Ψ
JT
= Junction-to-Top (of package) characterization parameter
is the Typical value from
Table 32
and
Table 33
.
P
D
= Power dissipation (see EE Note #216)
Values of
θ
JA
are provided for package comparison and PCB
design considerations.
θ
JA
can be used for a first order approxi-
mation of T
J
by the equation:
where:
T
A
= Ambient Temperature

Values of
θ
JC
are provided for package comparison and PCB
design considerations when an external heat sink is required.
Values of
θ
JB
are provided for package comparison and PCB
design considerations.
