GENERAL 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 compose 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.
FEATURES
4 direct data input pins. (direct keys)
One-time programmable process.
Programmable 8 bit customer code.
220 maximum address and data code.
An external oscillation resister.
10 ms of key de-bounce time for K0~K3 plus.
Available in SO or DIP package.
APPLICATIONS
Burglar alarm system, car door controllers, car alarm system, home/office security system…etc.
