The Auto RS-485 Half-Duplex Direction control feature simplifies both the hardware and software for half-duplex RS-485 applications. In addition, the Multidrop mode with Auto Address detection increases the performance by simplifying the software routines. The Independent TX/RX Baud Rate Generator feature allows the transmitter and receiver to operate at different baud rates. Power consumption of the M681 can be minmized by enabling the sleep mode and PowerSave mode. The M681 has a 16550 compatible register set that provide users with operating status and control, receiver error indications, and modem serial interface controls. An internal loopback capability allows onboard diagnostics. The M681 is available in 24-pin QFN, 32-pin QFN and 25-pin BGA packages. NOTE: 1 Covered by U.S. Patent #5,649,122.
