Description

The HT1611C 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 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 then the real time is displayed again. When making a phone call, the HT1611C receives the 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 HT1611C can provide a stopwatch function and timer reset/hold functions (for details, refer to the functional description).
