Product Summary

The MC6850 is an asynchronous communications interface adapter. It provides the data formatting and control to interface serial asynchronous data communications information to bus organized systems such as the MC6800 microprocessing unit. The bus interafce of the MC6850 includes select, enable, read/write, interrupt and bus interface logic to allow data transfer over an 8-bit bidirectional data bus.

Parametrics

MC6850 absolute maximum ratings: (1)supply voltage, VCC: -0.3 to 7.0V; (2)input voltage, Vin: -0.3 to 7.0V; (3)operating temperature range, TA: 0 to 70℃; (4)storage temperature range, Tstg: -55 to 150℃.

Features

MC6850 features: (1)8- and 9-bit transmission; (2)optional even and odd parity; (3)parity, overrun and framing error checking; (4)programmable control register; (5)optional +1, +16, and +64 clock modes; (6)up to 1.0 Mbps transmission; (7)false start bit deletion; (8)peripheral/modem control functions; (9)double buffered; (10)one- or two-stop bit operation.
