5.2 Recommended External Components
†
from XIN to GNDD and XOUT to GNDD (combining pin, trace and crystal capacitance) should be 35 pF
to 37 pF.
5.3 Recommended Operating Conditions
*Exceeding this limit will distort the LCD waveforms on other pins.

Parameter
3.3V Supply Voltage (V3P3SYS,
V3P3A)
V3P3A and V3P3SYS must be at the
same voltage
VBAT
Operating Temperature
Maximum input voltage on DIO/SEG
pins configured as DIO input. *
Depending on trace capacitance, higher or lower values for CXS and CXL must be used. Capacitance
