CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Oscillation Circuit)
4.3.3 OSC3 oscillation circuit
The S1C63808 has built-in the OSC3 oscillation circuit that generates the CPU's sub-clock (Max. 4.2 MHz)
for high speed operation and the source clock for peripheral circuits needing a high speed clock (pro-
grammable timer, FOUT output). The mask option enables selection of the oscillator type from CR
(external R type), CR (built-in R type) and ceramic oscillation circuit. When CR oscillation (external R
type) is selected, only a resistance is required as an external element. When ceramic oscillation is selected,
a ceramic oscillator and two capacitors (gate and drain capacitance) are required. When CR oscillation
(built-in R type) is selected, no external element is required.
Figure 4.3.3.1 is the block diagram of the OSC3 oscillation circuit.

Fig. 4.3.3.1 OSC3 oscillation circuit
As shown in Figure 4.3.3.1, the CR oscillation circuit (external R type) can be configured simply by
connecting the resistor RCR between the OSC3 and OSC4 terminals when CR oscillation is selected. See
Chapter 7, "Electrical Characteristics" for resistance value of RCR.
When ceramic oscillation is selected, the ceramic oscillation circuit can be configured by connecting the
ceramic oscillator (Max. 4.2 MHz) between the OSC3 and OSC4 terminals, capacitor CGC between the
OSC3 and OSC4 terminals, and capacitor CDC between the OSC4 and VSS terminals. For both CGC and
CDC, connect capacitors that are about 30 pF. To reduce current consumption of the OSC3 oscillation
circuit, oscillation can be stopped by the software (OSCC register).
