GENERAL DESCRIPTION
EM32117
16DIGITLCDDRIVERWITHCHECKTIMEFUNCTION
Preliminary
EM32117 is a CMOS 16-digit LCD panel driver. The EM32117 can receive dialing information such as dialing
digits, Pause, Flash, Pulse to Tone mode from EMC EM91465 series dialer IC and display the corresponding
pattern on the LCD panel. The EM32117 also supports various indicators such as the icons of STORE, SAVE,
Speaker phone (or Hand-Free), Lower or Upper page, Hold, etc. to support high-end feature phone applications.
The EM32117 can operate in stand-alone mode to display calendar and real time clock, conversation time
(stopwatch). The EM32117 also provides check the last conversation time function.
FEATURES
• ON-HOOK check last conversation time function.
• General flag display function for LOGO indication.
• Low power consumption: 1.5µA (max.)
• Uses single clock 32768 Hz crystal (with built-in capacitor, no need extra capacitor).
• LCD blank 2 sec after OFF-HOOK, to protect the STW data.
• Built-in serial data interface (compatiable with EM91465 series).
• Driver for 4.5-volt, 16-digit, 1/4 duty , 1/3 bias LCD panel with built-in voltage tripler circuit.
• Display dialing phone number.
• Display calendar and real time clock (RTC) in 12 hour or 24 hour format.
• Stopwatch function for counting conversation time up to 59 minutes 59 seconds.
• Operating voltage: 1.5 VDC ( typical )
• Dice form, QFP 80 pin package, and LCM (Liquid Crystal display Module) are available.
APPLICATION
• LCD Feature phone and Digital display system.

2. When lock condition establish.
3. MUTE and ALARM indicators will toggle with each received SDI code.
4. Any invalid data will be ignored by the EM32117.
• General flag display function. EM32117 provide General Flag Icon, when GF pin pull "high", then "GF" Icon
will be displayed. GF pin pull "low", the "GF" Icon will blank. The "GF" Icon can identify by user for special
distinguishment.
FUNCTION DESCRIPTION
Operation Modes and System States
Depending on which state the EM32117 is in, the system will operate in one of two modes, namely, RTC mode
and Stop-watch mode. In the State 1, as defined by the State-diagram in figure 4, the system operates in Real-
Time Clock mode, otherwise, the system operates in Stop-Watch mode. The flow chart is as follows:

Preliminary
• Then "505" are received.
• Then "21912345" are received, the display is as follows:
• 6 seconds after the last received digit, the EM32117 will go back to stop watch display.
.
• When the system reverts to State 1 with ENRTC* at low level, the Stop-watch will stop counting and stay on
the panel for 6 more seconds before it switches to RTC display. However, if ENRTC*is at high level when
the system returns to State 1, the LCD panel will go blank immediately.
Please refer to the following flow chart for detailed information.
Stop watch delay :
The last conversation time will prevent to be destroyed by stop watch delay function. After off-hook (or turn on
HF), STW will be displayed after 2 sec. This function is to prevent the user quickly ON-OFF HOOK to destroy
the last conversation time data.
* This specification are subject to be changed without notice.
