UARTs reduce footprint in industrial pcs
Exar has introduced two UARTs for the Intel Low Pin Count (LPC) motherboard bus.
The devices are targeted towards industrial pcs, factory automation, process controllers, network routers and single board embedded computers.
The XR28V382 is housed in a 5 x 5mm 32pin QFN package and includes two UART channels, while the XR28V384 has four UART channels and comes in a 7 x 7mm, 48pin TQFP package.
Both the two channel XR28V382 and four channel XR28V384 UARTs include Exar's automatic half duplex control for RS-485 networks.
The parts feature 128byte transmit and receive FIFOs, are rated for the industrial temperature range and operate at 3.3V. Each UART channel supports serial data rates up to 3Mb/s.
