LC709006A: I/O Expander for Microcontroller
The LC709006A 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 24-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.
特性- 4-/5-wire synchronous serial transmission and reception, and 24-bit parallel I/O
- Wide operating voltage range (2.0V to 6.0V)
- Multifunction I/O ports :I/O direction specification: Bit unitsCMOS or Nch-OD output type specification: Bit unitsOutput 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 24 bits x n (n is the number of LSI chips).
