M320EB
GENERAL DESCRIPTION
The M320EB is a 220 services of encoder pair with M320D utilizing CMOS LSI design for use in remote control system. The
M320EB is design by a one-time programmable process. They decide the transmission word of M320EB that compose of 4 data
bits, 20 address bits. A transmission word of the M320EB is transmitted on the DO pin via an RF transmission medium upon
receipt of a trigger signal.
FEATURES
4 direct data input pins, Up to 15 data combination.
12 seconds auto transmission out off to reduce power consumption.
Up to 220 (1,048,576) address codes.
An external oscillation resister.
One-time programmable process.
Available in SOP or DIP package.
APPLICATIONS
Burglar alarm system, car door controllers, car alarm system, home/office security system…etc.
