ECOPACK
In order to meet environmental requirements, ST offers these devices in different grades of
ECOPACK packages, depending on their level of environmental compliance. ECOPACK
specifications, grade definitions and product status are available at: www.st.com.

Thermal characteristics
The average chip-junction temperature, TJ must never exceed 125 °C.
The average chip-junction temperature, TJ, in degrees Celsius, may be calculated using the
following equation:
TJ = TA + (PD x ΘJA)(1)
Where:
TA is the ambient temperature in ° C,
ΘJA is the package junction-to-ambient thermal resistance, in ° C/W,
PD is the sum of PINT and PI/O (PD = PINT + PI/O),
PINT is the product of IDD and VDD, expressed in Watts. This is the Chip Internal Power.
PI/O represents the power dissipation on input and output pins;
Most of the time for the applications PI/O< PINT and may be neglected. On the other hand,
PI/O may be significant if the device is configured to drive continuously external modules
and/or memories. The worst case PINT of the STR91xFA is 500 mW (IDD x VDD, or 250 mA x
2.0 V).
An approximate relationship between PD and TJ (if PI/O is neglected) is given by:
PD = K / (TJ + 273 °C)
(2)
Therefore (solving equations 1 and 2):
K = PD x (TA + 273 °C) + ΘJA x PD
2
(3)
Where:
K is a constant for the particular part, which may be determined from equation (3) by
measuring PD (at equilibrium) for a known TA. Using this value of K, the values of PD
and TJ may be obtained by solving equations (1) and (2) iteratively for any value of TA.
