CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Oscillation Circuit)
4.3 Oscillation Circuit
4.3.1 Configuration of oscillation circuit
The S1C60N16 and S1C60L16 have one oscillation circuit (OSC1), and the S1C60A16 has two oscillation
circuits (OSC1 and OSC3). OSC1 is a crystal oscillation circuit that supplies the operating clock to the
CPU and peripheral circuits. OSC3 is either a CR or ceramic oscillation circuit. When processing with the
S1C60A16 requires high-speed operation, the CPU operating clock can be switched from OSC1 to OSC3.
Figure 4.3.1.1 is the block diagram of this oscillation system.

4.3.2 OSC1 oscillation circuit
The OSC1 oscillation circuit generates the main clock for the CPU and the peripheral circuits. The oscilla-
tor type is a crystal oscillation circuit and the oscillation frequency is 32.768 kHz (Typ.).
Figure 4.3.2.1 is the block diagram of the OSC1 oscillation circuit.

Fig. 4.3.2.1 OSC1 oscillation circuit
As shown in Figure 4.3.2.1, the crystal oscillation circuit can be configured simply by connecting the
crystal oscillator (X'tal1) of 32.768 kHz (Typ.) between the OSC1 and OSC2 terminals and the trimmer
capacitor (CGX) between the OSC1 and VSS terminals.
