MPU CISC 16-Bit 40-Pin PDIP

The Intel 8256AH Multifunction Universal Asynchronous Receiver-Transmitter (MUART) combines five commonly used functions into a single 40-pin device. It is designed to interface to the 8086/88, iAPX 186/188, and 8051 to perform serial communications, parallel I/O, timing, event counting, and priority interrupt functions. All of these functions are fully programmable through nine internal registers. In addition, the five timer/counters and two parallel I/O ports can be accessed directly by the microprocessor.

• Programmable Serial Asynchronous Communications Interface 5-, 6-, 7-, or 8-bit characters
• On-Board Baud Rate Generator Programmable for 13 common Baud Rates up to 19.2 Kbits/second or an external Baud Clock Maximum of 1M Bit/Second
