The low current drain is a distinctive feature of the LC5730 series microcontroller. However, it is not easy to determine the total current reguired for LC5730 series microcontroller-used system by actual measurement when you develop a software, bacause much current flows in the peripherals of the evaluation tools. For a system which requires low current drain, check the current drain using an evaluation sample before massproducting the system.

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 Electric 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.
