7 / 90 page CS49300 Family DSP DS339F7 7 1. CHARACTERISTICS AND SPECIFICATIONS (All Min/Max characteristics and specifications are guaranteed over the Specified Operating Conditions. Typical performance characteristics and specifications are derived from measurements taken at nominal supply voltages and TA = 25°C.) 1.1. Specified Operating Conditions (AGND, DGND = 0 V; all voltages with respect to 0 V) 1.2. Absolute Maximum Ratings (AGND, DGND = 0 V; all voltages with respect to 0 V) CAUTION: Operation at or beyond these limits may result in permanent damage to the device. Normal operation is not guaranteed at these extremes. 1.3. Thermal Data (VA, VD[3:1] = 2.5 V ±5%; measurements performed under operating conditions) Notes: 1. Two-layer board is specified as a 76 mm X 114 mm, 1.6 mm thick FR-4 material with 1-oz copper covering 20 % of the top & bottom layers. 2. Four-layer board is specified as a 76 mm X 114 mm, 1.6 mm thick FR-4 material with 1-oz copper covering 20 % of the top & bottom layers and 0.5-oz copper covering 90 % of the internal power plane & ground plane layers. 3. To calculate the die temperature for a given power dissipation Tj = Ambient Temperature + [ (Power Dissipation in Watts) * θ ja ] 4. To calculate the case temperature for a given power dissipation Tc = Tj - [ (Power Dissipation in Watts) * ψ jt ] Parameter Symbol Min Typ Max Unit DC power supplies: Positive digital Positive analog ||VA| – |VD|| VD VA 2.37 2.37 - 2.5 2.5 - 2.63 2.63 0.3 V V V Ambient operating temperature TA 0- 70 °C Parameter Symbol Min Max Unit DC power supplies: Positive digital Positive analog ||VA| – |VD|| VD VA –0.3 –0.3 - 2.75 2.75 0.3 V V V Input current, any pin except supplies Iin - ±10 mA Digital input voltage VIND –0.3 3.63 V Storage temperature Tstg –65 150 °C Parameter Symbol Min Typ Max Unit Thermal Resistance (Junction to Ambient) Two-layer Board (Note 1) Four-layer Board (Note 2) θ ja - - - - 44.5 36.3 °C / Watt Thermal Resistance (Junction to Top of Package) Two-layer Board (Note 1) Four-layer Board (Note 2) ψ jt - - - - 2.0 3.8 °C / Watt |
