EM94014/EM94015
WITH HANDSET LCD DISPLAY
GENERAL DESCRIPTION
EM94014/EM94015 is a set of 4-bit micro-controller specially designed for dual channel cordless phone.
These devices support 16-bit security code, dual channel, receiver power saving and two ways paging/intercom.
In addition, the handset unit battery low detection/indication, any key turn on while call is coming, base unit
power down mode for data protection and carrier detect are also included. The handset unit provides a SDO
interface for using with EM32100 10-digit LCD driver (1.5V supply voltage) which display dialing number,
channel number and CHK key function. All of this features are designed for high performance Cordless Phone
system applications.
