20 / 46 page  MCF5208 ColdFire® Microprocessor Data Sheet, Rev. 1 Electrical Characteristics Freescale Semiconductor 20 The average chip-junction temperature (TJ) in °C can be obtained from: Eqn. 1 Where: TA = Ambient Temperature, °C QJMA = Package Thermal Resistance, Junction-to-Ambient, ×C/W PD =PINT + PI/O PINT =IDD × IVDD, Watts - Chip Internal Power PI/O = Power Dissipation on Input and Output Pins — User Determined For most applications PI/O < PINT and can be ignored. An approximate relationship between PD and TJ (if PI/O is neglected) is: Eqn. 2 Solving equations 1 and 2 for K gives: Eqn. 3 where K is a constant pertaining to the particular part. K can 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 can be obtained by solving Equation 1 and Equation 2 iteratively for any value of TA. 5.3 ESD Protection 5.4 DC Electrical Specifications Table 6. ESD Protection Characteristics1, 2 NOTES: 1 All ESD testing is in conformity with CDF-AEC-Q100 Stress Test Qualification for Automotive Grade Integrated Circuits. 2 A device is defined as a failure if, after exposure to ESD pulses, the device no longer meets the device specification requirements. Complete DC parametric and functional testing is performed per applicable device specification at room temperature followed by hot temperature, unless specified otherwise in the device specification.
