HANDLING DEVICES
1. Preventing Latchup
Care must be taken to ensure that maximum voltage ratings are not exceeded (to prevent latchup) . When CMOS
integrated circuit devices are subjected to applied voltages higher than Vcc at input and output pins (other than
medium- and high-withstand voltage pins), or to voltages lower than Vss, as well as when voltages in excess of
rated levels are applied between Vcc and Vss, the phenomenon known as latchup can occur.
When a latchup condition occurs, supply current can increase dramatically and may destroy semiconductor
elements. In using semiconductor devices, always take sufficient care to avoid exceeding maximum ratings.
Also when switching power on or off to analog systems, care must be taken that analog power supplies (AVCC,
AVR) and analog input signals do not exceed the level of the digital power supply.
2. Power Supply Voltage Fluctuations
Keep supply voltage levels as stable as possible.
Even within the warranted operating range of the Vcc supply voltage, sudden changes in supply voltage can
cause abnormal operation. As a measure for stability, it is recommended that the Vcc ripple fluctuation (peak to
peak value) should be kept within 10% of the reference Vcc value on commercial power supply (50 Hz-60 Hz),
and instantaneous voltage fluctuations such as at power-on and shutdown should be kept within a transient
variability limit of 0.1V/ms.
3. Treatment of Unused Input Pins
If unused input pins are left open, abnormal operation may result. Any unused input pins should be connected
to pull-up or pull-down resistance.
4. Treatment of N.C. Pins
Any pins marked ’NC’ (not connected) must be left open.
5. Treatment of Power Supply Pins on Models with Built-in A/D Converter
Even when A/D converters are not in use, pins should be connected so that AV

, and

.
6. Precautions for Use of External Clock
Even when an external clock signal is used, an oscillator stabilization wait period is used after power-on reset,
or escape from sub clock mode or stop mode.
7. Execution of Programs on RAM
Debugging of programs executed on RAM cannot be performed even when using the MB89PV530.
8. Wild Register Functions
Wild registers cannot be debugged with the MB89PV530 and tools. To verify operations, actual in-device testing
on the MB89P538 or MB89F538L is advised.
