◇NOTES FOR POWER SUPPLY

In order to prevent an inadvertent write, the device has the feature of P.O.R.ꢀ

After the power is on, the device is in the write disable mode. P.O.R. works only during power up. The noise may force

the device write enable mode with CS=“H”during power ON/OFF. In the case of power up, keep the following

conditions to ensure to make the function of P.O.R.

Vcc waveform

Please keep CS “H” during power ON/OFF.

The device is an active state during CS is low. The extraordinary function or data collaption may occur because of

noise etc., if power-up is done with CS “L”. In order to prevent above errors from happening, keep CS “H” (=Vcc)

during power ON. (The device does not receive any command during CS is high.)

It may continue at low Vcc by capacitance of Vcc line during power off.

Please keep CS “H” during power off because of the device may make malfunction and inadvertent write.

Ｖｃｃ

（Good example）

Ｖｃｃ

CS follows Vcc. (CS is pull up to Vcc)

ＧＮＤ

Ｖｃｃ

（Bad example）

ＣＳ

CS is low during power ON/OFF.

ＧＮＤ

Good

Bad

Please take more than 10ms between power ON and power OFF,

or the internal circuit is not always reset.

◇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)

(4)

Heat design

In consideration of permissible dissipation in actual use condition, carry out heat design with sufficient margin.

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.
