SC73C1402B

SC73C1402 4-BIT MCU FOR REMOTE CONTROLLER(MASK TYPE) DESCRIPTION SC73C1402 is one of Silan’s 4-bit CMOS single-chip microcontrollers for infrared remote control transmitters (IRCTs). It can be implemented in various IRCT circuits by mask option. SOP-20-300-1.27 FEATURES * Operating voltage range: (2.0 ~ 4.0V) Low static power consumption (<1uA) SOP-20-375-1.27 * Program memory: 2Kx 9 bits The last 1K areas can also be used as data table * Data memory (RAM): 16 x 4 bits * Timer/counter: 10~15 bits SSOP-20-300-0.65 * 20 I/O ports, where there is a 4-bit input, two 4-bit outputs and two 4-bit programmable input/output ports(P53 is output but ORDERING INFORMATION not used as keypress). * Oscillator frequency (fosc): Device Package 300KHz~2MHz or 2MHz~6MHz selectable by mask option SC73C1402 SOP-24-375-1.27 * Operating frequency (fmain): SC73C1402A SOP-20-300-1.27 fmain=fosc (when fosc in the range of 300KHz~2MHz) SC73C1402B SSOP-20-300-0.65 fmain=fosc/8 (when fosc ...
