I2CXpress™
Versatile
New I²C protocol exerciser and analyzer
Pittsford, NY.
I2CXpress™
is a new, versatile USB2.0-connected I2C protocol exerciser/analyzer.
Ideal for all I2C bus system development and debug, it operates on standard I2C
protocol interfaces in low-speed (10 kbps), standard (100 kbps) and fast
(400 kbps) modes. For advanced systems, Fast (>1 Mbps) mode is also supported.
I2CXpress™ can be
used as an
I2C bus master as
well as an analyzer.
USB-powered I2CXpress™
is provided with
easy-to-use
8PI Control Panel
software, with a visual
PC interface to interact with embedded I²C systems. 8PI
Control Panel is supplied
with a TCL/tk scripting environment,
giving access to a
C/C++ DLL as well as the
graphical interface.
As an I2C master, I2CXpress™ allows communication with a network of I2C bus devices. It can address both 7-bit and 10-bit slaves, sending arbitrary length write and read data. It visually reports I2C bus events, such as missing acknowledge or bus arbitration loss.
As an I2C analyzer, I2CXpress™ oversamples the I2C bus, collects a selected number of raw data samples and isolates and decodes each I2C bus transaction. The collected data can be saved as decoded data, raw samples, and also a VCD file. Clock stretching and repeated start functions are supported, as is I2C-based flash memory access and multi-master capabilities.
I2CXpress™ is surprisingly compact at only 3.5” x 2” x 0.75” and less than 3oz. This compact, robust portable solution is an ideal I2C system development and debug field tool for any engineer’s tool-kit. Designed for chip-to-chip communication emulation at 3.3V LVTTL/LVCMOS, it can also operate at lower voltages. A plug-in board PLG-LCS-007 is available for accommodating higher I2C bus voltages (4.0 – 7.0V).
I2CXpress™ connects to any PC using Microsoft Windows XP or Vista operating systems, and is a hot Plug’n’Play device which can be attached and removed from the host computer without having to power-down or reboot. I2CXpress™ is fully bus-powered when the internal power supply mode is selected, and operates without needing any external power supply.
I2CXpress™ is available from stock now at $699.00 each from Saelig Co.
