MB89180 Series

(Continued)

(VCC = +5.0 V, AVSS = VSS = 0.0 V, TA = –40

°C to +85°C)

*1: The measurement conditions of power supply current are as follows: the external clock, open output pins, and

the external LCD dividing resistor. In the case of the MB89PV180, the current consumed by the connected

EPROM and ICE is not included.

*2: For information on tinst, see “(4) Instruction Cycle” in “4. AC Characteristics.”

Note: For pins which serve as the segment (SEG8 to SEG31) and ports (P10 to P17, P40 to P47, and P50 to P57),

see the port parameter when these pins are used as ports and the segment parameter when they are used

as segment pins.
