(Refer to Figure 2.) 1. The VDD becomes higher than the minimum operating voltage after the power is supplied. 2. The HOLD mode is released. The sample oscillation circuit characteristics may differ applications. For further assistance, please contact with oscillator manufacturer with the following notes in your mind. • Since the oscillation frequency precision is affected by wiring capacity of the application board, etc., adjust the oscillation frequency on the production board. • The above oscillation frequency and the operating supply voltage range are based on the operating temperature of -10°C to +70°C. For the use with the temperature outside of the range herein, or in the applications requiring high reliability such as car products, please consult with oscillator manufacturer. • When using the oscillator which is not shown in the sample oscillation circuit characteristics, please consult with SANYO sales personnel. Since the oscillation circuit characteristics are affected by the noise or wiring capacity because the circuit is designed with low gain in order to reduce the power dissipation, refer to the following notices. • The distance between the clock I/O terminal (XT1 terminal XT2 terminal) and external parts should be as short as possible. • The capacitors’ VSS should be allocated close to the microcontroller’s GND terminal and be away from other GND. • The signal lines with rapid state changes or with large current should be allocated away from the oscillation circuit.

To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer's products or equipment. SANYO Semiconductor Co., Ltd. strives to supply high-quality high-reliability products. However, any and all semiconductor products fail with some probability. It is possible that these probabilistic failures could give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design. In the event that any or all SANYO Semiconductor products (including technical data,services) described or contained herein are controlled under any of applicable local export control laws and regulations, such products must not be exported without obtaining the export license from the authorities concerned in accordance with the above law.
