4.1.2
Note 1: If you use a microcontroller device outside the 0 to 85 C range for long periods of time, contact
Note 2: For the •ja value, contact your nearest Toshiba office or authorized Toshiba dealer.
For microcontroller devices, the following junction temperature range is used for reliability
predictions:
An estimation of the chip junction temperature, Tj, can be obtained from the equation:
Tj = 0 C
Tj = Ta + Q •ja
where:
your nearest Toshiba office or authorized Toshiba dealer.
Reliability predictions for microcontroller devices
Ta = ambient temperature ( C)
Q =
•ja = package thermal resistance ( C/W)
85 C
The assumption is that the ambient temperature is not affected by any heat
transfers from the device.
