Characteristics of a Sample Subsystem Clock Oscillator Circuit
Given below are the characteristics of a sample subsystem clock oscillation circuit that are measured using a SANYOdesignated oscillation characteristics evaluation board and external components with circuit constant values with which the oscillator vendor confirmed normal and stable oscillation. Table 2 Characteristics of a Sample Subsystem Clock Oscillator Circuit with a Crystal Oscillator EPSON TOYOCOM
Nominal Frequency Type Oscillator Name C1 [pF] 32.768kHz SMD MC-306 9 Circuit Constant C2 [pF] 9 Rf [] Open Rd [] 330k Operating Voltage Range [V] 1.8 to 5.5 Oscillation Stabilization Time typ [s] 1.4 max [s] Applicable 4.0 CL value = 7.0pF 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 3). 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.

Figure 7 Waveform observed when only POR is used (LVD not used) (RESET pin: Pull-up resistor RRES only) * The POR function generates a reset only when power is turned on starting at the VSS level. * No stable reset will be generated if power is turned on again when the power level does not go down to the VSS level as shown in (a). If such a case is anticipated, use the LVD function together with the POR function or implement an external reset circuit. * A reset is generated only when the power level goes down to the VSS level as shown in (b) and power is turned on again after this condition continues for 100s or longer.

Figure 8 Waveform observed when both POR and LVD functions are used (RESET pin: Pull-up resistor RRES only) * Resets are generated both when power is turned on and when the power level lowers. * A hysteresis width (LVHYS) is provided to prevent the repetitions of reset release and entry cycles near the detection level.
