HANDLING DEVICES
Take note of the following nine points when handling devices :
Do not exceed maximum rated voltage (to prevent latch-up)
Supply voltage stability
Power-on precautions
Treatment of unused pins
Treatment of A/D converter power supply pins
Notes on using an external clock
Power supply pins
Sequence for connecting and disconnecting the A/D converter power supply and analog input pins
Notes on using the DIV A, Ri and DIVW A, RWi instructions
Device Handling Precautions
(1) Do not exceed maximum rated voltage (to prevent latch-up)
Do not apply a voltage grater than V
CC
or less than V
SS
to the MB90560/565 series input or output pins. Also
ensure that the voltage between V
CC
and V
SS
does not exceed the rating. Applying a voltage in excess of the
ratings may result in latch-up causing thermal damage to circuit elements.
Similarly, when connecting or disconnecting the power to the analog power supply (AV
CC
, AVR) and analog
inputs (AN0 to AN7) , ensure that the analog power supply voltages do not exceed the digital voltage (V
CC
) .
(2) Supply voltage stability
Rapid changes in the V
CC
supply voltage may cause the device to misoperate. Accordingly, ensure that the V
CC
power supply is stable. The standard for power supply voltage stability is a peak-to-peak V
CC
ripple voltage at
the supply frequency (50 to 60 Hz) of 10
%
or less of V
CC
and a transient fluctuation in the voltage of 0.1 V/ms
or less when turning the power supply on or off.
(3) Power-on precautions
To prevent misoperation of the internal regulator circuit, ensure that the voltage rise time at power-on is at least
50
μ
s (between 0.2 V to 2.7 V) .
(4) Treatment of unused pins
Leaving unused input pins unconnected can cause misoperation or permanent damage to the device due to
latchup. Always pull-up or pull-down unused pins using a 2 k
or larger resistor.
If some I/O pins are unused, either set as outputs and leave open circuit or set as inputs and treat in the same
way as input pins.
(5) Treatment of A/D converter power supply pins
If not using the A/D converter, connect the analog power supply pins so that AV
CC
=
AVR
=
V
CC
and AV
SS
=
V
SS
.
(6) Notes on using an external clock
Even if using an external clock, an oscillation stabilization delay time occurs after a power-on reset and when
recovering from stop mode in the same way as when an oscillator is connected. When using an external clock,
drive the X0 pin only and leave the X1 pin open.
