UART 1-CH 5V 44-Pin PLCC

安富利:
The 82C50A Asynchronous Communication Element ACE is a high performance programmable Universal Asynchronous Receiver/Transmitter UART and Baud Rate Generator BRG on a single chip. Using Intersil’s advanced Scaled SAJI IV CMOS Process, the ACE will support data rates from DC to 625K baud 0-10MHz clock.The ACE’s receiver circuitry converts start, data, stop, and parity bits into a parallel data word. The transmitter circuitry converts a parallel data word into serial form and appends the start, parity, and stop bits. The word length is programmable to 5, 6, 7, or 8 data bits. Stop bit selection provides a choice of 1,1.5, or 2 stop bits.The Baud Rate Generator divides the clock by a divisor programmable from 1 to 216-1 to provide standard RS- 232C baud rates when using any one of three industry standard baud rate crystals 1.8432MHz, 2.4576MHz, or 3.072MHz. A programmable buffered clock output BAUDOUT provides either a buffered oscillator or 16X 16 times the data rate baud rate clock for general purpose system use.To meet the system requirements of a CPU interfacing to an asynchronous channel, the modem control signals RTS, CTS, DSR, DTR, RI, DCD are provided. Inputs and outputs have been designed with full TTL/CMOS compatibility in order to facilitate mixed TTL/NMOS/CMOS system design.
