Exar’s New LPC UARTs Reduce Footprint in Industrial PCs

Fremont, Calif., January 27, 2014 – Exar Corporation (NYSE: EXAR), a leading supplier of high performance analog mixed-signal components and data management solutions, today announced the XR28V382 and XR28V384 UARTs for the Intel Low Pin Count (LPC) motherboard bus. The new LPC UARTs reduce footprint while increasing data integrity and throughput by providing industry leading 128 byte FIFOs.  These devices are targeted towards industrial PCs, factory automation, process controllers, network routers, and single board embedded computers.

The XR28V382 is packaged in a small 5x5mm 32 pin QFN and includes two UART channels, while the XR28V384 has four UART channels in a 7x7mm 48 pin TQFP.  Exar’s dual and quad LPC UARTs, compared to 128 pin super I/O devices, offer the same or more serial channels in a significantly smaller footprint, offering as much as 8X reduction in board space.

“These new LPC UARTs are a great replacement or supplement for a super I/O device when the primary need is serial connectivity,” said Jack Roan, product marketing manager, Exar.  “They are also an excellent alternative to USB UARTs; they interface directly with the system BIOS so there is no need to install a driver, and they are inherently compatible with multiple operating systems because the device is configured before the OS loads.”

Product Details

Both the two channel XR28V382 and four channel XR28V384 UARTs include Exar’s automatic half duplex control for RS-485 networks.  These parts feature 128 byte transmit and receive FIFOs, are rated for the industrial temp range, and operate at 3.3V.  Each UART channel supports serial data rates up to 3Mbps.

Suggested retail prices for XR28V382 and XR28V384 are $2.40 and $3.50 respectively, in 1,000-unit quantities.

Designing Robust 5G Power Amplifiers for the Real World

Sponsored by Keysight

Simulating 5G power amplifier (PA) designs at the component and system levels with authentic modulation and high-fidelity behavioral models increases predictability, lowers risk, and shrinks schedules. Simulation software enables multi-technology layout and multi-domain analysis, evaluating the impacts of 5G PA design choices while delivering accurate results in a single virtual workspace. This application note delves into how authentic modulation enhances predictability and performance in 5G millimeter-wave systems.
