GENERALDESCRIPTION
EM91865
13 MEMORY TONE/PULSE DIALER WITH HF, HD, REDIAL
AND VOLUME CONTROL FUNCTION
Preliminary
The EM91865 are 13 memory tone/pulse switchable dialer with Last Number Redail (LNB) anD SAVE function,
Which are fabricate in CMOS technology with wide operating voltage for both tone and pulse mode. EM91865
consumes very low memory retention current in on hook state. The EM91865 provide necessary functions of
telephone set for application in any environment, such as pulse dialing, tone (DTMF)dialing, handfree dialing. Beside
this, hold, mute and redial function are provide for particular operation. In redial mode EM91865 can auto insert
pause time for application in PABX system. EM91865 also have a special I/O pin - VAO can used tocontrol
the receive volume amplify circuit.
