Table 2 Characteristics of a Sample Subsystem Clock Oscillator Circuit with a CF Oscillator Nominal Frequency Vendor Name EPSON TOYOCOM Circuit Constant Oscillator Name C3 [pF] 32.768kHz MC-306 18 C4 [pF] 18 Rf [Ω] OPEN Rd2 [Ω] 510k Operating Voltage Range [V] 2.7 to 5.5 Oscillation Stabilization Time typ [s] 1.1 max [s] 3.0 Applicable CL value=12.5pF Remarks The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized after the instruction for starting the subclock oscillation circuit is executed and to the time interval that is required for the oscillation to get stabilized after the HOLD mode is reset (see Figure 4). Note: The components that are involved in oscillation should be placed as close to the IC and to one another as possible because they are vulnerable to the influences of the circuit pattern.
