1 / 150 page  CD1865 Intelligent Eight-Channel Communications Controller Datasheet Product Features s Eight full-duplex asynchronous channels supporting data rates up to 115.2 kbps Note: To support this data rate, the specified system clock frequency is required. s Register-based interrupt acknowledges eliminate need for separate interrupt acknowledge signals s Automatic prioritizing scheme allows device to respond to an interrupt acknowledge with the highest internal interrupt pending (host-programmable) s Sophisticated interrupt schemes — Vectored interrupts — Fair Share interrupts —Good Data interrupts for improved throughput — Simultaneous interrupt requests for three classes of interrupts: Rx, Tx, and modem state changes s Independent baud-rate generators for each channel/direction s Software compatibility with the CD180 and CD1864 devices s Generation and detection of special characters s Automatic flow control — In-band (Xon, Xoff generation, and detection) — Out-of-band (DTR/DSR or RTS/CTS) s On-chip FIFO — 8 bytes each for Rx, Tx, and Status s Line break detection and generation s Multiple-chip daisy-chain cascading feature s Odd, even, forced, or no parity s modem/general-purpose I/O signals per channel s System clock up to 66 MHz (x2), 33MHz (x1) s CMOS technology in 100-pin MQFP As of May 18, 2001, this document replaces the Basis Communications Corp. document CL-CD1865 — Intelligent 8-Channel Communications Controller.
