Dual UART (universal asynchronous receiver/transmitter) ICs with wide power supply range (2,25 V - 5,5 V) and on-chip transmit (TX) and receive (RX) FIFO (first-in, first-out) of 64-byte depth with FIFO counters are now available from Exar. Applications include portable computer systems, point-of-sales handheld terminals, PDAs among others. The 64-byte FIFO depth in the XR16L275x product family lengthens intervals between CPU interrupt, and the TX and RX FIFO counters shorten the time for each interrupt service; both features minimise CPU bandwidth requirements and increase system throughput, according to the company.
The XR16L275x (dual UARTs) support data rates up to 6,125 Mbps at 5,0 V, 4 Mbps at 3,3 V, and 3 Mbps at 2,5 V at an eight times (8x) sampling rate. These 64-byte FIFO depth devices provide an easy migration path to Exar's 128-byte FIFO products.
The XR16L2750, XR16L2751 and XR16L2752 have automatic hardware (RTS/CTS) flow control and hysteresis, plus automatic software (Xon/Xoff) flow control to eliminate RX data overflow. In addition, these devices support automatic RS485 half-duplex direction control output - enabling and speeding up two-wire polling operation.
