Single Channel, Low Voltage Solution • Two 16 Byte FIFO versions (M570, M580) • Two 32 Byte FIFO versions (M670, M680) • Two 64 Byte FIFO versions (M770, M780) • Packages • QFN and TQFP for socket compatibility • BGA to address new customers needs and applications • Low voltage (1.8V-3.3V), high performance (up to 16Mbps)
Key Features • Different Tx/Rx Data Rates (New Feature) • Increase design flexibility • Lower total system design cost for customers • 4X/8X Sampling Options (New Feature) • Allows selection of slower clock/crystal sources to generate faster baud rate • Fractional Baud Rate Generator (New Feature) • Achieve desired baud rate with any crystal • Multidrop (New Feature) • Point-to-multipoint support for RS-485 networks • Hardware and Software Flow Control • Built-in support to prevent overrun errors • Auto RS-485 Half-Duplex Direction Control • Built-in hardware to prevent data loss
Benefits Why use single-channel, low voltage UARTs? • Highest performance at lower supply voltage • 16Mbps (3.3V) • 12.5Mbps (2.5V) • 7.5Mbps (1.8V) • Overall System Cost Reduction • FBRG • 4X/8X Sampling Option • Different Tx/Rx Data Rates • Ease of Migration with pin and software compatibility • Shorter Time To Market • Easier to add UART than to upgrade to new CPU
