XR17D158IV-F Typical application Circuitry

XR17D158IV-F

The XR17D158IV-F is part of the XR17D158 series from Exar Corporation, now a part of MaxLinear. This chip is an octal universal asynchronous receiver-transmitter (UART) with integrated level shifters, designed primarily for applications requiring multiple serial interfaces. It can handle up to eight independent serial ports and is often used in environments where space and power efficiency are critical, such as in telecommunications, industrial control, and network management systems.

1. Power Supply Connections: The XR17D158IV-F operates with dual power supply connections. Connect VCC to a 3.3V supply (Pin 11) and VCCIO to 1.8V or 3.3V, depending on the required logic level for the interface (Pin 10). Ensuring stable power supplies is vital for maintaining reliable serial communications.

2. Serial Port Connections: The device features eight UART channels, each requiring connections for transmit (TX) and receive (RX) lines. For example, connect TX0 and RX0 (Pins 100 and 99) for the first channel, TX1 and RX1 (Pins 98 and 97) for the second, and so on, through TX7 and RX7 (Pins 64 and 63) for the eighth channel. This setup allows for robust multi-port communication.

3. Clock Input: A 16 MHz or 24 MHz external clock is required for the XR17D158IV-F and should be connected to the XTAL1 pin (Pin 24). This clock ensures the correct timing for all UART operations. The XTAL2 pin (Pin 23) can be left floating or connected to a crystal or clock output if a crystal is used.

4. Interrupt Request Line (IRQ): Connect the IRQ pin (Pin 12) to the host processor to enable interrupt-driven communication, which improves efficiency by notifying the CPU of events such as data receipt or transmission completion without polling the UART.

5. Register Configuration via Bus Interface: The device supports both Motorola and Intel bus interfaces for register configuration. Connect the Chip Select (CS), Read (RD), Write (WR), and Data Bus (D0-D7, Pins 55-62) to configure device settings and control operations through the host processor's bus.

6. Grounding and Decoupling: Connect all ground pins (e.g., Pins 3, 5, 18) to a common ground plane to reduce noise and ensure signal integrity. Additionally, use decoupling capacitors near the power pins to stabilize the power supply voltage and minimize transient voltage spikes.

7. Package and Heat Management: Since the XR17D158IV-F comes in a 100-pin LQFP package, ensure proper soldering and PCB layout to avoid thermal issues. Heat sinks or thermal pads may be necessary depending on the operating environment and power dissipation.

By following these detailed connection steps, you can effectively deploy the XR17D158IV-F in applications requiring multiple serial interfaces, ensuring reliable and efficient operation in systems with extensive data communication needs.
