MB89170/170A/170L Series

Figure 1 and figure 2 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: 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.
