M320EA
DESCRIPTION
The M320EA is a 220 services of encoder pair with M320D utilizing CMOS LSI design for use in remote control system. The M320EA is design by a one-time programmable process. They decide the transmission word of M320EA that pose of 4 bit data bits, 20 bit address bits. A transmission word of the M320EA is transmitted on the DO pin via an RF or an infra-red transmission medium upon receipt of a trigger signal.
