Digital Clock  
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)
