MB89910 Series

Figure 1 indicates the operating frequency of the external oscillator at an instruction cycle of 4/FCH.

Since the operating voltage range is dependent on the instruction cycle, see minimum execution time if the

operating speed is switched using a gear.

WARNING: Recommended operating conditions are normal operating ranges for the semiconductor device. All

the device’s electrical characteristics are warranted when operated within these ranges.

Always use semiconductor devices within the recommended operating conditions. 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 representative beforehand.
