Fonctionnalités et applications

The XR17V354 (V354) is a single chip 4-channel PCI Express (PCIe) UART (Universal Asynchronous Receiver and Transmitter), optimized for higher performance and lower power. The V354 serves as a single lane PCIe bridge to 4 indepedent enhanced 16550 compatible UARTs. The V354 is compliant to PCIe 2.0 Gen 1 (2.5GT/s).

In addition to the UART channels, the V354 has 16 multi-purpose I/Os (MPIOs), a 16-bit general purpose counter/timer and a global interrupt status register to optimize interrupt servicing. Each UART of the V354 s many enhanced features such as the 256-bytes TX and RX FIFOs, programmable Fractional Baud Rate Generator, Automatic Hardware or Software Flow Control, Auto RS-485 Half-Duplex Direction Control, programmable TX and RX FIFO Trigger Levels, TX and RX FIFO Level Counters, infrared mode, and data rates up to 25 Mbps. The V354 is available in a 176-pin fpBGA package (13 x 13 mm).

Features:

  • Single 3.3 V power supply
  • Internal buck regulator for 1.2 V core
  • PCIe 2.0 Gen 1 compliant
  • x1 Link, dual simplex, 2.5 Gbps in each direction
  • EEPROM interface for configuration
  • Data read/write burst operation
  • Global interrupt status register for both UARTs
