The HT1613C is a CMOS chip designed for dialer interfaces driving 8 or 10 digit LCDs. Various functions, such as real time clock, dialing number and conversation time display are provided.
The HT1613C can display the real time or be blank by default. When answering a telephone call, the timer is activated to tell users how long the conversation has taken. It receives dialing data from the dialer and displays the phone number on the LCD from left to right each time a phone call is made. By adding a TIMER key, the HT1613C can provide the stopwatch and timer reset/hold functions. Refer to the functional description for details.
