Product Summary
The MC68681FN is a dual universal asynchronous receiver/transmitter. It is part of the M68000 family of peripherals and directly interfaces to the MC68000 processor via an asynchronous bus structure. The MC68681FN consists of eight major sections: internal control logic, timing logic, interrupt control logic, a bidirectional 8-bit data bus buffer, two independent communication channels (A and B), a 6-bit parallel input port, and 8-bit parallel output port.
Parametrics
MC68681FN absolute maximum ratings: (1) Input high voltage: 2.0V; (2) Input low voltage: 4.0V; (3) Output low voltage: 0.4V; (4) Input leakage current: -10μA to 10μA; (5) Load capacitance: 50pF.
Features
MC68681FN features: (1)Parity, Framing, and Overrun Error Detection; (2)False-Start Bit Detection; (3)Line-Break Detection and Generation; (4)Detects Break Originating in the middle of a character; (5)Start/End Break Interrupt/Status; (6)On-chip Crystal oscillator; (7)TTL compatible ; (8)Single +5V power supply.
