* Low static power consumption (<1mA)

* ROM: 2K x 9 bits

* Data memory: 32 x 4bits

* Timer/counter: (10~15 bits)

* 8-bit timer, generates various frequencies and duty carrier

* 16 I/O pins, four 4-bit I/O ports (export P53)

* Oscillator frequency (fosc): fosc=4MHz (TYP.) or fosc=455KHz(TYP.)

* Operating frequency (fmain): fosc/8 (fosc=4MHz)

fosc (fosc=455KHz)

* Instruction cycle: 5/fmain

* Support low voltage detection

APPLICATIONS

* Infrared remote control devices, such as TV, Video Cassette Recorder, VTR, laser phonograph and acoustics remote controllers.
