GENERAL DESCRIPTION

MSM5547 is a clock IC having a wide power supply range with 4.194304 MHz original

oscillation. MSM5547 is a 12 hour cycle AM/PM clock for a static fluorescent character display

tube. Time correction is in hour, minute and 30 minute adjustments. Hour and minute are

corrected by a 2 Hz fast-forward function. MSM5547 also has a contrast adjustment function for

the fluorescent character display tube, which can set four levels of contrast, including 100%

duty.

FEATURES

• 12 hour clock (AM/PM)

• Applied for static fluorescent character display tube

• Wide power supply range: 4 to 16V

• 4.194304 MHz original oscillation

• 4 levels of contrast can be selected

• Package options:

44-pin plastic QFP (QFP44-P-910-0.80-L2)

(Product name: MSM5547GS-L2)
