(4)Power supply pins (Vcc/Vss)
In products with multiple VCC or VSS pins, pins with the same potential are internally connected in the device to
avoid abnormal operations including latch-up. However, you must connect the pins to an external power and a
ground line to lower the electro-magnetic emission level to prevent abnormal operation of strobe signals caused
by the rise in the ground level, and to conform to the total current rating.
Make sure to connect VCC and VSS pins via lowest impedance to power lines.
It is recommended to provide a bypass capacitor of around 0.1
F between VCC and VSS pin near the device.
(5) Pull-up/down resistors
The MB90590/590G Series does not support internal pull-up/down resistors. Use external components where
needed.
(6) Crystal Oscillator Circuit
Noises around X0 or X1 pins may cause abnormal operations. Make sure to provide bypass capacitors via the
shortest distances from X0, X1 pins, crystal oscillator (or ceramic resonator) and ground lines, and make sure
that lines of oscillation circuits do not cross the lines of other circuits.
A printed circuit board artwork surrounding the X0 and X1 pins with a ground area for stabilizing the operation
is highly recommended.
(7) 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 AN7) 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 does not exceed AVRH or AVCC (turning on/off the analog and digital power supplies simulta-
neously is acceptable).
(8) Connection of Unused Pins of A/D Converter
Connect unused pins of A/D converter to AVCC = VCC, AVSS = AVRH = VSS.
