Description  
TQFP52  
The EM6625 is an ultra-low power, low voltage  
microcontroller with an integrated 3/4 MUX  
x 20  
segments LCD driver and the equivalent of 8kB mask  
ROM. It features temperature compensated LCD voltage  
levels, free LCD segment allocation and built-in voltage  
multipliers. It also has a melody generator, a millisecond  
counter (BCD) and PWM function. Tools include  
windows-based simulator and emulator. A flexible MFP  
version is also available for development stage.  
Due to its very low current consumption, the EM6625 is  
ideal for use in battery-operated and field-powered  
applications.
