    产品信息

    The LC709004A is a peripheral IC dedicated for expanding the capability of the microcontroller (MCU) I/O ports. It interfaces with the microcontroller through synchronous serial communication. Communication with the extended I/O ports is accomplished through 16-bit parallel I/O. The extended port features include the capabilities to specify the I/O direction on a bit basis, to specify the output type (CMOS or N-channel open drain), and to specify the I/O voltage level on a port basis according to the power level of the peripheral equipment. These features make allow the LC709004A to be used in a wide variety of applications.
    • 4-/5-wire synchronous serial transmission and reception, and 16-bit parallel I/O
    • Wide operating voltage range (2.0V to 6.0V)
    • Multifunction I/O ports :
    • I/O direction specification: Bit units
    • CMOS or Nch-OD output type specification: Bit units
    • Output voltage adjustment: Port (8 bits) units
    • Output current: 12mA max. (capable of driving a green LED directly)
    • Data transmission and reception :
    • Can control reception of input data and transmission of output data in parallel.
    • Cascaded configuration :
    • Ports can be expanded in units of 16 bits x n (n is the number of LSI chips).
