The recommended operating conditions are required in order to ensure the normal operation of the semiconductor device. All of the device’s electrical characteristics are warranted when the device is operated within these ranges.

Always use semiconductor devices within their recommended operating condition ranges. Operation outside these ranges may adversely affect reliability and could result in device failure.

No warranty is made with respect to uses, operating conditions, or combinations not represented on the data sheet. Users considering application outside the listed conditions are advised to contact their FUJITSU representatives beforehand.

The oscillation time of the oscillator is the time it takes for the amplitude of the oscillations to reach 90%. For crystal oscillators, this time is between several ms and several tens of ms to reverse engineering MB90F345CA microcontroller flash memory, for ceramic oscillators the time is between several hundred ms and several ms, and for an external clock, the time is 0 ms.

Resolution        : Analog variation that is recognized by the A/D converter.

Non linearity error

Differential linearity error : The deviation between the actual conversion characteristics and a line that joins the

zero-transition line ( “00 0000 0000” ¬ ® “00 0000 0001” ) to the full-scale transition line

( “11 1111 1110” ¬ ® “11 1111 1111” ) . : Deviation of input voltage, which is required for changing output code by 1 LSB, from an ideal value.

Use the device with external circuits of the following output impedance for analog inputs :

Recommended output impedance of external circuits are : Approx. 1.5 kL or lower (4.0 V £ AVCC £ 5.5 V,

sampling period = 0.5 ms)
