Description  
CVRR  
The EM6635 is a low voltage, low power microcontroller  
containing 9 integrated high-drive outputs able to provide  
up to 20mA. It is ideal for use in applications in which one  
must drive devices such as motor drivers, small stepping  
motors, LEDs, triacs, external EEPROM or other ICs in  
the system.  
32kHz Xtal  
Applications  
EM6635 has both a 32kHz crystal oscillator and a  
500kHz RC oscillator without external component, as well  
as an external clock to be driven up to 4MHz.  
The CPU operating clock can be switched from crystal to  
RC oscillator for high-speed operation.

Toys  
It has  
a
frequency/melody generator with 255  
Sensor interface  
programmable frequencies for quality buzzer.  
The EM6635 contains the equivalent of 8kB mask ROM  
and the RAM has a capacity of 256x4 bits.  
It also has a power-on reset, watchdog timer, 2 timers  
8bits, 2 BCD counters, 3bits event counter, 4 wire serial  
port 8bits and several clock functions.
