SC73C1402

4•BIT MCU FOR REMOTE CONTROLLER(MASK TYPE)

DESCRIPTION

SC73C1402 is one of Silan’s 4•bit CMOS single•chip micro•

controllers for infrared remote control transmitters (IRCTs)I.t can

be implemented in various IRCT circuits by mask option.

SOP•20•300•1.27

SOP•20•375•1.27

FEATURES

* Operating voltage range: (2.0 ~ 4.0V)

Low static power consumption (<1uA)

* Program memory: 2Kx 9 bits

The last 1K areas can also be used as data table

* Data memory (RAM): 16 x 4 bits

SSOP•20•300•0.65

* Timer/counter: 10~15 bits

* 20 I/O ports, where there is a 4•bit input, two 4•bit outptus and

two 4•bit programmable input/output ports(P53 is output b
