HT1616C -- Timer with Dialer Interface
|
|
| 概要 |
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. |
