General Description  
The HT48RA3 is an 8-bit high performance, RISC archi-  
tecture microcontroller device specifically designed for  
multiple I/O control product applications. The data ROM  
can be used to store remote control codes. This device  
is the OTP version which is fully pin and functionally  
compatible with mask version HT48CA3 device.  
The advantages of low power consumption, I/O flexibil-  
ity, timer functions, oscillator options, watchdog timer,  
programmable frequency divider, HALT and wake-up  
functions, as well as low cost, enhance the versatility of  
this device to suit a wide range of application possibili-  
ties such as industrial control, consumer products, sub-  
system controllers, and particularly suitable for use in  
products such as universal remote controller (URC).
