Reliability of Microcontrollers
For microcontroller products, reliability can be estimated within the following
temperature range.
Tj = 0
°
C to 85
°
C
Tj (junction temperature) can be calculated using the following formula:
Tj = Ta + Q
×
θ
ja
Ta: Operating environment temperature for the product
C
]
The operating environment temperature is the temperature of the
surrounding environment. The thermal effects of the operation of the
product are not taken into account.
Q: Average power consumption of the product
[
W
]
θ
ja: Thermal resistance of the package
C / W
]
Note 1: When operating the device outside the range Tj = 0
°
C to 85
°
C for
extended periods, please contact your nearest Toshiba office or
authorized Toshiba dealer.
Note 2: For details of the value of
θ
ja, please contact your nearest Toshiba office
or authorized Toshiba dealer.
