The Micro/sys USB196 is a high density digital I/O board that implements the new StackableUSB™ standard.
Montrose, CA (PRWEB) May 24, 2007 -- The Micro/sys USB196 is a high density digital I/O board that implements the new StackableUSB™ standard. The USB196 offers high quantities of digital I/O for OEM systems by providing four 82C55’s that support 96 TTL I/O lines. The 8-position DIP switch and 8 LEDs can be used for debugging during system development, for station number, or configuration settings in the final production system. All discrete I/O lines have software programmable pull-ups or pull-downs. Protecting against power sequencing problems, the robust USB196 prevents overload currents with onboard current-limiting resistors.
At the core of the USB196 is a Silicon Laboratories C8051F340 microcontroller unit that runs at 48 MHz. This core is compatible with 8051 architecture and integrates many peripherals such as the 10-bit A/D converter, 2 UARTs, 1 I2C, and 1 SPI bus, all of which are available to the user. Due to a predefined protocol that carries data over the USB, it is not necessary to modify the code which runs on the USB196. In conjunction with this protocol, host applications, via a custom driver, can directly access and control all of the onboard peripherals. Therefore, the only code that needs to be modified to control the USB196 resides on the host CPU. This expansion board also has USB 2.0 compatibility which supports both full speed (12 Mbps) and low speed (1.5 Mbps).
The rugged USB196 is rated for operation over the industrial temperature range of – 40°C to +85°C. It also supports power management so that it can be placed in a low power mode to conserve power, an issue that is paramount to embedded systems relying on battery power or environments where heat generation is a key concern.
StackableUSB™ allows this expansion board to operate as a USB device when stacked above or below a host CPU board. The StackableUSB™ interface on the USB196 utilizes star or point-to-point architecture that directs communication up the stack to the next peripheral in line. This brings USB technology into rugged, compact spaces, making it an ideal choice for industrial applications. Supporting automatic enumeration, StackableUSB™ also allows the host to detect devices plugged into the stack and to install the drivers necessary for the system to operate with minimal human intervention. Up to four of these USB peripheral boards can be stacked in any combination, or with other I/O boards, satisfying the growing demand for flexible and faster board-to-board connection.
The USB196 starts at $145 in single quantity. Significant OEM quantity discounts are available. Contact Technical Sales Dept., Micro/sys, Inc., 3730 Park Place, Montrose, CA, 91020, phone (818) 244-4600, FAX (818) 244-4246, www.embeddedsys.com.
