GENERAL DESCRIPTION
AMD’s Am85C30 is an enhanced pin-compatible version of the popular Am8530H Serial Communications Controller. AMD’s proprietary enhancements make the Am85C30 easier to interface and more effective in high-speed applications due to a reduction in software burden and the elimination of the need for some external glue logic. The Am85C30 is easy to use due to a variety of sophisticated internal functions, including on-chip baud rate generators, digital phase-locked loops, and crystal oscillators, which dramatically reduce the need for external logic. The device can generate and check CRC codes in any SYNC mode, and can be programmed to check data integrity in various modes. The ESCC also has facilities for modem controls in both channels. In applications where these controls are not needed, the modem controls can be used for general-purpose I/O. This versatile device supports virtually any serial data transfer application such as networks, modems, cassettes, and tape drivers.
