Power supply pins (VCC/VSS)
If there are multiple VCC and VSS pins, from the point of view of device design, pins to be of the same potential
are connected the inside of the device to prevent such malfunctioning as latch up.
To reduce unnecessary radiation, prevent malfunctioning of the strobe signal due to the rise of ground level,
and observe the standard for total output current, be sure to connect the VCC and VSS pins to the power supply
and ground externally.
Connect VCC and VSS to the device from the current supply source at a low impedance.
As a measure against power supply noise, connect a capacitor of about 0.1
F as a bypass capacitor between
VCC and VSS in the vicinity of VCC and VSS pins of the device.
6.
Pull-up/down resistors
The MB90390 Series does not support internal pull-up/down resistors. Use external components where needed.
7.
Crystal Oscillator Circuit
Noises around X0 or X1 pins may be possible causes of abnormal operations. Make sure to provide bypass
capacitors via shortest distance from X0, X1 pins, crystal oscillator (or ceramic oscillator) and ground lines, and
make sure, to the utmost effort, that lines of oscillation circuit not cross the lines of other circuits.
It is highly recommended to provide a printed circuit board art work surrounding X0 and X1 pins with a ground
area for stabilizing the operation.
8.
Turning-on Sequence of Power Supply to A/D Converter and Analog Inputs
Make sure to turn on the A/D converter power supply (AVCC, AVRH, AVRL) and analog inputs (AN0 to AN14)
after turning-on the digital power supply (VCC) .
Turn-off the digital power after turning off the A/D converter supply and analog inputs. In this case, make sure
that the voltage not exceed AVRH or AVCC (turning on/off the analog and digital power supplies simultaneously
is acceptable) .
9.
Connection of Unused Pins of A/D Converter if A/D Converter is unused
Connect unused pins of A/D converter to AVCC
= VCC, AVSS = AVRH = AVRL = VSS.
10. Notes on Energization
To prevent the internal regulator circuit from malfunctioning, set the voltage rise time during energization at 50
or more
s (0.2 V to 2.7 V) .
11. Notes on During Operation of PLL Clock Mode
If the PLL clock mode is selected, the microcontroller attempt to be working with the self-oscillating circuit even
when there is no external oscillator or external clock input is stopped. Performance of this operation, however,
cannot be guaranteed.
