4 PRECAUTIONS ON MOUNTING18 EPSON S1C05251 TECHNICAL MANUAL In order to prevent generation of electromagnetic induction noise caused by mutual inductance, do not arrange alarge current signal line near the circuits that are sensitive to noise such as the oscillation unit. When a signal line is parallel with a high-speed line in long distance or intersects a high-speed line, noise maygenerated by mutual interference between the signals and it may cause a malfunction.Do not arrange a high-speed signal line especially near circuits that are sensitive to noise such as the oscillationunit.OSC4OSC3V SSLarge current signal lineHigh-speed signal lineProhibited pattern Visible radiation causes semiconductor devices to change the electrical characteristics. It may cause this IC tomalfunction. When developing products which use this IC, consider the following precautions to preventmalfunctions caused by visible radiations.(1) Design the product and implement the IC on the board so that it is shielded from visible radiation in actualuse.(2) The inspection process of the product needs an environment that shields the IC from visible radiation.(3) As well as the face of the IC, shield the back and side too. |
