Handling Device

•

Preventing latch-up

Latch-up may occur in CMOSIC when a voltage higher than V

CC-CPU

or lower than V

SS-CPU

is applied to the

input or output pins, or a voltage exceeding the rated value is applied between V

CC-CPU

and V

SS-CPU

. Latch-

up may cause a rapid increase in the supply current, sometimes resulting in thermal damage to the device.
Therefore, keep the used voltage within the maximum ratings.

When turning the power on and off the analog supply voltage (AV

) analog input should not exceed the

digital supply voltage (V

CC-CPU

•

Voltage supplies should be stabilized.

A sudden change of the power supply voltage may cause a malfunction even within the guaranteed range
of operation of the V

CC-CPU

power supply voltage.

For reference of stabilization, voltage variations are recommended to be restrained so that V

CC-CPU

ripple

variations (P-P values) are below 10% of the standard V

CC-CPU

value in commercial frequencies (50 to 60

Hz), and so that transient variation is below 0.1 V/ms in sudden changes during power switchovers.

•

Precautions when turning on the power supply

Ensure a minimum of 50

s (between 0.2 to 2.7 V) for voltage rise times when turning on the power supply

to prevent malfunction of the built-in power reduction circuit.

•

Handling of unused input pins

Leaving unused input pins open may cause a malfunction. Therefore, these pins should be connected to a
pull-up or a Pull-down resistor.

•

Handling of A/D converters power supply pins

Connect power supply pins with AV

= V

CC-CPU

, AV

= V

CC-IO

even when not using the A/D converters.

•

Precautions when using the external clock

Oscillating stability waiting time is required when resetting from the Power On Reset, Stop Mode when
using the external clock.

•

Order of turning on the power

Turn off the digital power supply (V

CC-CPU

) after turning off the A/D converter power supplie (AV

CC,

)

and analog input (AN0 to AN15).

Do not allow the input voltage to exceed AV

when using the analog input pins as an input port.
