M320EA中文资料一华半导体数据手册PDF规格书

GENERAL DESCRIPTION

The M320D learning decoder is CMOS LSI for remote control system application. It decoder the encoded waveform generated by

M320EA/M320EB and drives data output pin(s) according to the code bits decoded from the received waveform. Up to 1,048,576

address codes that Interface with EEPROM (93LC46) can be stored 32 sets of customer codes at maximum.

FEATURES

‧ Operating voltage 2.4V~5.5V.

‧ Pairs with M320EA/M320EB OTP encoders.

‧ Maximum 1,048,576 address and data code.

‧ 4 Data active: D0, D1, D2, D3.

‧ VT goes high during valid receiving.

‧ Selectable latch or momentary type of data output.

‧ An external oscillator resistor and capacitor.

‧ Interface with EEPROM (93LC46) can be stored 32 sets of customer codes at maximum.

‧ Learning capability and the LED current for learning status indication.

APPLICATIONS

‧ Burglar alarm system, car door controllers, car alarm system, home/office security system…etc.
