6. Crystal Oscillator Circuit
Noise around the X0 and X1 pins may cause abnormal operation in this device. In designing printed circuit
boards, the X0 and X1 pins and crystal oscillator (or ceramic oscillator), as well as the bypass capacitor to the
ground, should be placed as close as possible, and the related wiring should have as few crossings with other
wiring as possible.
Circuit board artwork in which the area of the X0 and X1 pins is surrounded by grounding is recommended for
stabilizing the operation.
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, D/A converter power supply (AV
CC
, AVRH, AVRL, DV
CC
,
DV
SS
) and analog inputs (AN0 to AN7) after turning on the digital power supply (V
CC
).
Turn off the digital power after turning off the A/D converter supply and analog inputs. In this case, make sure
that AVRH and DV
CC
do not exceed AV
CC
(turning on/off the analog and digital supplies simultaneously is
acceptable).
8. Connection of Unused Pins of A/D Converter
Connect unused pins of A/D converter and those of D/A converter to AV

9. N.C. Pin
The N.C. (internally connected) pin must be opened for use.
10.Notes on Energization
To prevent the internal regulator circuit from malfunctioning, set the voltage rise time during energization at
50
μ
s or more (0.2 V to 2.7 V).
11.Use of SEG/COM Pins for the LCD Controller/Driver as Ports
In MB90520 series, pins SEG08 to SEG31, and COM0 to COM3 can also be used as general-purpose ports.
The electrical standard is such that pins SEG08 to SEG23, and COM0 to COM3 have the same ratings as the
CMOS output port, while pins SEG24 to SEG31 have the same ratings as the open-drain type.
