Description
The EM93010RXA is an electronic component model in the product category of IC Chips. It belongs to the series of tone/pulse switchable dialers, specifically the EM91210 series. This series provides all the necessary functions of a telephone set for application in any environment, including pulse dialing, tone (DTMF) dialing, handfree dialing, keying tone, mute, and pulse mute functions. It also features the SDO (Serial Data Output) function, designed to drive LCD drivers and voice synthesizers. With the support of an LCD screen, the dialing numbers can be displayed using the EM32100 (or EM32116) in this application.
