Fig.5Using LDO REGULATOR Part, Regulation Timing I/O APPLICATION CIRCUIT Pull up resistor is indispensable condition. When CSB is "H" during power ON/OFF, error operating and writing is protected. PULL UP RESISTOR OF CSB PIN The pull up resistor is needed in order to prevent error operating and writing from happening. Decide the value of this resistor (Rup) properly, considering VOH, IOH characteristics of controller.

CAUTIONS ON USE (1) Absolute maximum ratings If the absolute maximum ratings such as impressed voltage and operating temperature range and so forth are exceeded, LSI may be destructed. Do not impress voltage and temperature exceeding the absolute maximum ratings. In the case of fear exceeding the absolute maximum ratings, take physical safety countermeasures such as fuses, and see to it that conditions exceeding the absolute maximum ratings should not be impressed to LSI. (2) GND electric potential Set the voltage of GND terminal lowest at any action condition. Make sure that each terminal voltages is lower than that of GND terminal. (3) Heat design In consideration of permissible dissipation in actual use condition, carry out heat design with sufficient margin. (4) Terminal to terminal shortcircuit and wrong packaging When to package LSI onto a board, pay sufficient attention to LSI direction and displacement. Wrong packaging may destruct LSI. And in the case of shortcircuit between LSI terminals and terminals and power source, terminal and GND owing to foreign matter, LSI may be destructed. (5) Strong electromagnetic field Use in a strong electromagnetic field may cause malfunction, therefore, evaluated design sufficiently.
