Overview
MOSDESIGN SEMICONDUCTOR CORP.
220 OTP ENCODER EN/DECODER M320EA 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.
