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,
