Notes: "at RES'' means ''at reset time'' and ''in PD'' means ''in power down mode''.

MSM80C85A-2. Although the supply current range (at a power failure) of the MSM80C85AH does

not contain that of the MSM80C85A-2, this does not affect the actual use of the MSM80C85AH.

3-3) AC Characteristics

The AC characteristics (5 MHz) of the MSM80C85AH satisfy that (3 MHz) of the MSM80C85A. The

MSM80C85AH also satisfies that (5MHz) of the MSM80C85A.
