The HD-6402 is a CMOS UART for interfacing computers ormicroprocessors to an asynchronous serial data channel.The receiver converts serial start, data, parity and stop bits.The transmitter converts parallel data into serial form andautomatically adds start, parity and stop bits. The data wordlength can be 5, 6, 7 or 8 bits. Parity may be odd or even.Parity checking and generation can be inhibited. The stopbits may be one or two or one and one-half whentransmitting 5-bit code.The HD-6402 can be used in a wide range of applicationsincluding modems, printers, peripherals and remote dataacquisition systems. Utilizing the Intersil advanced scaledSAJI IV CMOS process permits operation clock frequenciesup to 8.0MHz (500K Baud). Power requirements, bycomparison, are reduced from 300mW to 10mW. Statuslogic increases flexibility and simplifies the user interface.
