■ HANDLING DEVICES
Make sure you do not exceed the maximum rated values (in order to prevent latch-up) .
CMOS IC chips may suffer latch-up if a voltage higher than VCC or lower than VSS is applied to an input or
output pin with other than mid or high current resistance; or voltage exceeding the rating is applied across VCC
and VSS pins.
Latch-ups can dramatically increase the power supply current, causing thermal breakdown of the device.
Make sure that you do not exceed the maximum rated value of your device, in order to prevent a latch-up.
When turning the analog power supply on or off, make sure that the analog power voltage (AVCC, AVR) and
analog input voltages do not exceed the digital voltage (VCC) .
Handling Unused Pins
Leaving unused input/output pins open may cause malfunctions and latch-ups, permanently damaging the
device. Prevent this by connecting it to a pull-up or pull-down resistor of no less than 2 k
Ω. Leave unused input/
output pins open in output mode, or if in input mode, handle them in the same as input pins.
Notes on Using External Clock
When using the external clock, drive pin X0 only, and leave pin X1 unconnected. See below for an example of
external clock use.
Example External Clock Use
Notes on Not Using Subclock
If you do not connect pins X0A and X1A to an oscillator, use pull-down handling on the X0A pin, and leave the
X1A pin open.
Power Supply Pins
If your product has multiple VCC or VSS pins, pins of the same potential are internally connected in the device
in order to avoid abnormal operation, including latch-up. However, you should make sure to connect the pins’
external power and ground lines, in order to lower unneeded emissions, prevent abnormal operation of strobe
signals due to a rise in ground levels, and maintain total output current within rated levels.
Take care to connect the VCC and VSS pins of MB90495G Series devices to power lines via the lowest possible
impedance.
It is recommended that you connect a bypass capacitor of approximately 0.1
μF between VCC and VSS pins near
MB90495G Series device pins.
Crystal Oscillator Circuit
Noise in the vicinity of X0 and X1 pins could cause abnormal operations in MB90495G Series devices. Make
sure to provide bypass capacitors via the shortest possible distance from X0 and X1 pins, crystal oscillators
(or ceramic resonators) , and ground lines. In addition, design your printed circuit boards so as to keep X0
and X1 wiring from crossing other wiring, if at all possible.
It is strongly recommended that you provide printed circuit board artwork surrounding X0 and X1 pins within
a grand area, as this should stabilize operation.
