Industrial and high-speed 16C UARTs

NXP UARTs

NXP, an established leader as a long-term supplier in UARTs, provides innovative solutions to meet the application requirements of today and tomorrow

INDUSTRIAL UARTS

NXP, the number-one supplier of industrial UARTs, offers a broad line of single- to eight-channel devices that deliver higher baud rates, superior error handling, deeper FIFOs, improved character recognition, responsive interrupt systems, and very fast host-bus cycle times. The latest implementation of the basic NXP UART architecture, the IMPACT family, offers special features – like lower operating voltage, programmable interrupt priority, and selectable Motorola/Intel bus interfaces

– that lower overall cost, speed time-to-market, and improve system performance. A single IMPACT device can be used in multiple operating systems and in multiple applications, so designers can bring several systems to market using the same high-performance, simple-to-use UART.

16C UARTS

NXP’s enhanced 16C UARTs are drop-in compatible with industry-standard devices and offer added features without a price premium.

The family includes CMOS-based, single- to quad-channel

UARTs that support the widest supply voltage range (1.8, 2.5,

3.3 and 5 V), operate within the industrial temperature range

(-40 to 85 °C), deliver baud rates up to 20 Mbps, and offer bus cycle times that are up to 20% faster than traditional devices.

Many are available in tiny HVQFN and TFBGA packages that reduce PCB space by as much as 70%. The 16C UARTs are fully compatible with Linux and Windows OS drivers, thus saving precious design time and lowering overall cost.

SPECIAL NXP FEATURES

Both families of UARTs employ an architecture that has been carefully optimized for superior performance. Programmable channel modes increase flexibility and make diagnostics easier to run. Multi-drop support (also known as “RS-485” or “ 9-bit” mode) allows half-duplex long distance communication.

Hardware handshaking uses modem control signals to control the data stream, preventing FIFO overflow without interrupting the CPU.

NXP Bridges

NXP bridge ICs are the new generation of serial interface solutions for managing host-to-device communications among wide variety of serial bus interfaces such as I

2

C, SPI, and UART. Our bridges allow you to simply connect devices that use a different serial bus than your current system. These products operate at low voltages, consume little power, and come in ultra-small packaging.

They are ideal for battery-operated applications. In addition, our bridges improve overall system performance by reducing software overhead while increasing design flexibility.

A host processor may not be able to communicate with devices using multiple I

2

C, SPI, UART, IrDA, and GPIO interfaces. For many advanced applications, multiple bus ports are required. Without using our bridges, host processing and system complexity can be overwhelming. Our bridges free up processor resources for code and data memory by handling the interfacing directly. Our bridge products are optimized for high speed data throughput.
