The MAX3107EAG+ is an enhanced-performance universal asynchronous receiver-transmitter (UART) designed with low power consumption in mind. It is a member of the MAX3100 family of UARTs in the interface-controllers family of devices. The MAX3107EAG+ is an ideal device for communication interface applications between the microprocessor and peripheral interfaces such as serial-to-parallel, parallel-to-serial, or isolated serial interfaces.

The advantages of the MAX3107EAG+ UART over conventional UARTs are as follows. It offers low power consumption through operating at lower supply voltages than comparable devices, an internal oscillator for autonomous operation, improved jitter performance, and enhanced power-saving modes of operation. The device achieves long character times, short timeouts, fast switch rates, and wide frequency range.

The MAX3107EAG+ has a wide range of applications. It can be used in personal computing and networking, industrial process control, medical instrumentation, and automotive environments. It is also ideal for point-of-sale terminals, consumer and automotive instrumentation, and wireless and wireline communications.

The central device in the MAX3107EAG+ UART is an 8-bit Rx/Tx shift register with an asynchronous serial bus interface that performs parallel/serial conversion. This shift register can be accessed from either the parallel bus or the serial data bus. The device includes control logic to enable or disable the transfer of data. The device is powered by two voltage supplies, a 1.45V to 1.9V for the core supply and Vcc for the output stages, which can range from 1.4V up to 5V. The MAX3107EAG+ also has an integrated oscillator circuit for self-operating UARTs without the need for a separate clock signal.

The MAX3107EAG+ also includes a number of hardware features to improve system performance. These include an extended true parallel bus interface, Auto-ID functionality with support of seven programmed protocol types, SmartConnect feature with one-clock setup time, an AutoRx wake-up timer, and an adaptive wake-up timer. The device also has an accelerated FIFO access mode and three priority control modes for reducing access latency. Additionally, the device has two independent receive FIFOs for buffering data, and two DMA request lines for background transfers.

In summary, the MAX3107EAG+ offers the enhanced performance and low power consumption of a modern UART with its 8-bit shift register, extended parallel bus, adaptive wake-up timer, and Auto-ID protocol support. This makes it an ideal choice for a range of interfaces, personal computing and networking, industrial process control, medical instrumentation, automotive applications, and point-of-sale terminals.
