4 / 34 page MCF548x ColdFire® Microprocessor, Rev. 4 Maximum Ratings Freescale Semiconductor 4 1 Maximum Ratings Table 1 lists maximum and minimum ratings for supply and operating voltages and storage temperature. Operating outside of these ranges may cause erratic behavior or damage to the processor. 2 Thermal Characteristics 2.1 Operating Temperatures Table 2 lists junction and ambient operating temperatures. Table 1. Absolute Maximum Ratings Rating Symbol Value Units External (I/O pads) supply voltage (3.3-V power pins) EVDD –0.3 to +4.0 V Internal logic supply voltage IVDD –0.5 to +2.0 V Memory (I/O pads) supply voltage (2.5-V power pins) SD VDD –0.3 to +4.0 SDR Memory –0.3 to +2.8 DDR Memory V PLL supply voltage PLL VDD –0.5 to +2.0 V Internal logic supply voltage, input voltage level Vin –0.5 to +3.6 V Storage temperature range Tstg –55 to +150 oC Table 2. Operating Temperatures Characteristic Symbol Value Units Maximum operating junction temperature Tj 105 oC Maximum operating ambient temperature TAmax <851 1 This published maximum operating ambient temperature should be used only as a system design guideline. All device operating parameters are guaranteed only when the junction temperature lies within the specified range. oC Minimum operating ambient temperature TAmin –40 oC |
