General Description  
The HT46R72D-1 is an 8-bit high performance, RISC  
architecture microcontroller device specifically de-  
signed for A/D with LCD applications that interface di-  
rectly to analog signals, such as those from sensors.  
The advantages of low power consumption, I/O flexibil-  
ity, timer functions, oscillator options, Dual slope A/D  
converter, LCD display, HALT and wake-up functions,  
watchdog timer, as well as low cost, enhance the versa-  
tility of these devices to suit for a wide range of AD with  
LCD application possibilities such as sensor signal pro-  
cessing, scales, consumer products, subsystem con-  
trollers, etc.
