Many systems have mixture devices designed 3.3V power supplies. such systems, carry both 3.3V 5V-compatible voltage levels standard 3.3V designed receive maximum voltage 3.3V during normal operation without causing damage). This 5V-tolerant capability therefore offers power savings 3.3V levels while being able receive levels without being damaged. Absolute maximum ratings given Table stress ratings only, functional operation maximum guaranteed. Stress beyond these ratings affect device reliability cause permanent damage device. 56F803 DC/AC electrical specifications preliminary from design simulations.

This model most useful ceramic packages with heat sinks; some heat flow dissipated through case heat sink ambient environment. ceramic packages, situations where heat flow split between path case alternate path through PCB, analysis device thermal performance need additional modeling capability system level thermal simulation tool. thermal performance plastic packages more dependent temperature which package mounted. Again, estimations obtained from satisfactorily answer whether thermal performance adequate, system level model appropriate. Definitions: complicating factor existence three common definitions determining junction-to-case thermal resistance plastic packages: Measure thermal resistance from junction outside surface package (case) closest chip mounting area when that surface proper heat sink.

When heat sink used, junction temperature determined from thermocouple inserted interface between case package interface material. clearance slot hole normally required heat sink. Minimizing size clearance important minimize change thermal performance caused removing part thermal interface heat sink. Because experimental difficulties with this technique, many engineers measure heat sink temperature then back-calculate case temperature using separate measurement thermal resistance interface. From this case temperature, junction temperature determined from junction-to-case thermal resistance.
Electrical Design Considerations
CAUTION
This device contains protective circuitry guard against damage high static voltage electrical fields. However, normal precautions advised avoid application voltages higher than maximum rated voltages this high-impedance circuit. Reliability operation enhanced unused inputs tied appropriate voltage level.
following list considerations assure correct operation: Provide low-impedance path from board power supply each hybrid controller, from board ground each (GND) pin. minimum bypass requirement place capacitors positioned close possible package supply pins. recommended bypass configuration place bypass capacitor each VDD/VSS pairs, including VDDA/VSSA. Ceramic tantalum capacitors tend provide better performance tolerances. Ensure that capacitor leads associated printed circuit traces that connect chip (GND) pins less than inch capacitor lead. Bypass layers with approximately preferably with highgrade capacitor such tantalum capacitor. Because controller's output signals have fast rise fall times, trace lengths should minimal.

Electrical Design Considerations
Consider device loads well parasitic capacitance traces when calculating capacitance. This especially critical systems with higher capacitive loads that could create higher transient currents circuits. Take special care minimize noise levels VREF, VDDA VSSA pins. Designs that utilize TRST JTAG port OnCE module functionality (such development debugging systems) should allow means assert TRST whenever RESET asserted, well means assert TRST independently RESET. TRST must asserted power proper operation. Designs that require debugging functionality, such consumer products, TRST should tied low. Because Flash memory programmed through JTAG/OnCE port, designers should provide interface this port allow in-circuit Flash programming.
