mb90480b/485b series 16 ds07-13722-11e handling devices 1. be careful never to exceed maximum rated voltages (preventing latch-up) in cmos ic devices, a condition known as latch-up may occur if voltages higher than v cc or lower than v ss are applied to input or output pins other than medium-o r high-voltage pins, or if the voltage applied between v cc and v ss pins exceeds the rated voltage level. when latch-up occurs, the power supply current increa ses rapidly causing the pos sibility of thermal damage to circuit elements. therefore it is necessary to ensure th at maximum ratings are not exceeded in circuit operation. similarly, when turning the analog power supply on or off, it is necessary to ensure that the analog power supply voltages (av cc and avrh) and analog input voltages do not exceed the digital power supply (v cc ) . 2. treatment of unused pins leaving unused input pins unconnect ed can cause abnormal operation or latch-up, leading to permanent damage. unused input pins should always be pulled up or down through resistance of at least 2 k . any unused input/output pins may be set to output mode and left open, or set to input mode and treated the same as unused input pins. 3. treatment of power supply pins (v cc /v ss ) when multiple v cc /v ss pins are present, device design considerat ions for prevention of latch-up and unwanted electromagnetic interference, abnormal strobe signal operation due to ground level rise, and conformity with total output current ratings require that all power suppl y pins must be externally connected to power supply or ground. consideration should be given to connec ting power supply sources to the v cc /v ss pins of this device with as low impedance as possible. it is also recommended th at a bypass capacitor of approximately 0.1 f be placed between the v cc and v ss lines as close to this device as possible. 4. crystal oscillator circuits noise around the x0/x1, or x0a/x1a pins may cause this device to operate abnormally. in the interest of stable operation it is strongly recommended that printed circui t board artwork places ground bypass capacitors as close as possible to the x0/x1, x0a/x1 a and crystal oscillator (or ceramic oscillator) and that oscillator lines do not cross the lines of other circuits. 5. precautions when turning the power supply on in order to prevent abnormal operation in the chip?s intern al step-down circuits, a voltage rise time during power- on of 50 s (0.2 v to 2.7 v) or greater should be assured. 6. supply voltage stabilization even within the operating range of v cc supply voltage, rapid voltage fluctu ations may cause abnormal operation. as a standard for power supply voltage stability, it is recommended that the peak-to-peak v cc ripple voltage at commercial supply frequency (50/60 hz) be 10 % or less of v cc , and that the transient voltage fluctuation be no more than 0.1 v/ms or less when the power supply is turned on or off. 7. proper power-on/off sequence the a/d converter power (av cc , avrh) and analog input (an0 to an7) mu st be turned on afte r the digital power supply (v cc ) is turned on. the a/d converter power (av cc , avrh) and analog input (an0 to an7) must be shut off before the digital power supply (v cc ) is shut off. care should be taken that avrh does not exceed av cc . even when pins used as analog input pins are doubled as input ports, be sure that the in put voltage does not exceed av cc .
mb90480b/485b series ds07-13722-11e 17 8. treatment of power supply pins on models with a/d converters even when the a/d converters are not in use, be sure to make the necessary connections av cc = avrh = v cc , and av ss = v ss . 9. notes on using power supply only the mb90485b series usually uses a 3 v power supply. by setting v cc 3 = 3 v power supply and v cc 5 = 5 v power supply, p20 to p27, p30 to p37, p40 to p47 and p70 to p77 can be interfaced as 5 v power supplies separately from the main 3 v power supply. note that the analog power supplies (such as av cc and av ss ) for the a/d converter can be used only as 3 v power supplies. 10. notes on using external clock even when using an external clock signal, an oscillation stabilization delay is applied after a power-on reset or when recovering from sub-clock or stop mode. when us ing an external clock, 25 mhz should be the upper frequency limit. the following figure shows a sample use of external clock signals. 11. treatment of nc pins nc (internally connected) pins should always be left open. 12. notes on during operation of pll clock mode on this microcontroller, if in case the crystal oscillator breaks off or an external reference clock input stops while the pll clock mode is selected, a self-oscillator circuit contained in the pll may c ontinue its operation at its self-running frequency. however, fujitsu will not guar antee results of operation if such failure occurs. 13. when the mb90480b/485b series microcon troller is used as a single system when the mb90480b/485b series microcontroller is us ed as a single system, use connections so the x0a = v ss , and x1a = open. 14. writing to flash memory for writing to flash memory, always ensure that the operating voltage v cc is between 3.0 v and 3.6 v. x0 x1 open
