Description

The HT1616C is a CMOS chip designed for dialer interfaces driving 12 or 16-digit LCDs. Various functions, such as real time clock, dialing number and conversation time display are provided.

For HT1616C the real time is displayed by default. When answering a telephone call, the timer is activated to tell users how long the conversation has taken. After the telephone is hung up, the total conversation time is shown for about 5 seconds and the real time is displayed again. When making a phone call, the HT1616C receives dialing data from the dialer and displays the phone number from left to right on the LCD. However, if there is no dialing action within 10 seconds, it restarts the timer again. By adding a TIMER key, the IC can provide stopwatch and timer reset/hold functions. Refer to the functional description for details.
