The smallest form factor available, for internally adding serial ports to any embedded system

Native single-chip design means up to 48% less load on your CPU which is critical for small embedded PCs that use low power, low MHz CPUs

Four high speed RS232 serial ports with data transfer rates up to 921.6 Kbps

High Performance 16650 UART

Includes 4x 30cm IDC to DB9 serial cables

256-byte deep FIFO per transmitter and receiver

Native single-chip, single lane PCI Express

In-band software flow control, using programmable Xon/Xoff in both directions

The MPEX4S952 4-Port RS232 Mini PCI Express Serial Card (16650 UART) turns a mini-PCIe slot into four RS232 (DB9) serial ports with data rates up to 921.6 Kbps - a cost-saving solution for adding serial support to embedded systems missing the functionality. A native PCIe single-chip design enables you to take advantage of full PCI Express bus capability, by providing improved speed and reliability while reducing the load applied to the CPU by as much as 48% over conventional "bridge chip" serial cards .
