Exar's new USB 2.0 compliant UART
interface IC works at 12 Mbps
Exar Corporation has released USB 2.0 compliant UART interface
IC with up to 12Mbps serial data rate. The series is composed
of three devices coded as - XR21V1410/V1412/V1414. The XR21V1410/V1412/V1414
are offered in small package, optimized software drivers,
and support large FIFO sizes of 128 Byte Tx and 384 bytes
Rx delivering flexible and proven design options to system
architects.
"The series of devices offer the lowest Bill of Materials
(BOM) costs, minimal system overhead and are designed in
space saving packages that are less than half the size of
competitive solutions," said Levent Ozcolak, vice president,
Interface Product Line. "With hardware and software
tool kits readily available, system architects can quickly
design in these devices to meet rapidly changing time-to-market
requirements."
The XR21V1410/V1412/V1414 series are suitable for embedded
system applications, gaming systems, ATM machines, and industrial
automation systems. For consumer applications, the series
is suggested for smart phones, Personal Digital Assistants
(PDAs), GPS systems, DVD players/recorders and gaming systems
and other portable applications.
"Adding enhanced capabilities to our market-leading
UART portfolio of 8-bit, PCI, I2C/SPI, VLIO, and wireless
UARTs, this new series of USB compliant solutions immediately
opens new opportunities to support our customers' next generation
applications," said Rakesh Bhatia, senior manager,
strategic marketing, Interface Products Line. "In addition,
when added to Exar's serial transceiver and power management
products we can offer a complete and optimized solution
for serial communications designs."
The other key product features are,
1. The XR21V1410, XR21V1412, and XR21V1414 have a USB slave
interface, which is compliant with Full-Speed
USB 2.0 specification.
2. Support USB suspend, resume and remote wakeup operations.
3. The features include automatic hardware (RTS/CTS or DTR/DSR)
flow control, automatic software (Xon/Xoff)
flow control, and multi-drop mode with auto half-duplex
transceiver control.
4. Doesn't require an external crystal/oscillator
5. Software drivers are available for Windows 2000, XP,
Vista, and CE, Mac and Linux.
6. Operate from a single 2.97 to 3.63 volt power supply
with the core operating at 1.2V to minimize overall
power consumption.
