4 FUNCTIONAL DESCRIPTION
SBN6400G
www.DataSheet4U.com
64-COMMON Driver for Dot-Matrix STN LCD
4.1 On-chip RC oscillator
When operating in master mode, the SBN6400G’s on-chip RC-type oscillator is used to provide clocks and necessary
control signals to itself, its slave, and the SBN0064G SEGMENT Driver.
External resistor Rf and capacitor Cf need to be connected across R, CR, and C, as shown in Fig. 5. The recommended
value for Rf is 33K ohm and that for Cf is 20 pF. During PCB layout, the resistor and the capacitor should be placed as
close to the SBN6400G as possible, such that stray capacitance, inductance, and resistance can be minimized.
Note:
(1) When operating in slave mode,
the C and R terminals should be
left open and the CR terminal
should be connected to VDD.

(2) When operating in master mode
and using an external clock
source, the C and R terminals
should be left open and external
clock source should be added to
the CR terminal.
