The HT1609L is an LCD driver LSI with 2´40 output channels using CMOS technology. It is equipped with two sets of 40-bit bidirectional shift registers, 40-bit data latches, 40-bit LCD drivers, and logic control circuits.
The HT1609L can convert serial data received from an LCD controller into parallel data and send out LCD driving waveforms to the LCD panel. The HT1609L is designed for general purpose LCD drivers. It can drive both static and dynamic drive LCDs. The LSI can be used as segment driver.
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).
The HT1612 is a CMOS chip designed for dialer interface which drives 8 or 10 digits LCD. Various functions, such as displaying dialing number and conversation time, are provided.
It normally shows blanks. The timer is started to tell users how long the conversation time has been taken when answering a telephone call. After hanging up the telephone, it returns to show blanks immediately. Whenever makeing a phone call, the HT1612 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 HT1612 can provide the timer reset/hold functions (refer to functional description for more details).
