*1 : The upper row indicates the power supply voltage for the 1.5V specification(product example: MSM64152A) while the lower row indicates the power supply voltage for the 3.0V specification(product example: MSM64152AL).
*2 : This is at crystal oscillation. Approximately 32 kHz at RC oscillation.
*3 : Dual clocks are supported(32.768 kHz crystal).
*4 : Eight ports can be selected as output ports from the LCD drivers by the mask option.
Example: MSM64162A(at 1/4 duty, 1/3 bias)
If the port specification is not selected by the mask option: Number of I/O ports: 4; Number of segments: 80(20 seg. x 4 com.)
If the port specification is selected by the mask option: Number of I/O ports: 12; Number of segments: 48(12 seg. x 4 com.)
*5 : Battery check circuit
*6 : For MSM64162A and ML64168, the voltage regulator circuit for LCD can be selected by the mask option.
*7 : ES products can be supplied. Check the specifications prior to use, since the polarity of the power supply is different.
*8 : An OPT product with the same power supply polarity as that of a mask product(ML64168) is being provided.
