April 2, 2009 -- Wavecom, a provider of embedded wireless technology for M2M (machine-to-machine) communication, has adopted the XJTAG IEEE Std. 1149.x boundary scan system as the platform for developing and testing its WMP100 Wireless Microprocessor-based turnkey systems. Wavecom’s system solutions are used across a range of M2M applications including automotive telematics, smart metering, fleet management, GSM/GPS/satellite tracking, wireless alarms, wireless point of sale, and remote monitoring.

The Wavecom WMP100 processor unites application hosting and cellular Internet connectivity in a power optimized single-core sub-system. The 576-pin ball grid array (BGA) device is used by Wavecom’s customers and in-house product developers to create turnkey products targeting specific applications.

Laurence Damm, a field application engineer with Wavecom, said: "We needed a boundary scan system to access and verify the pins on the various BGA devices on our development boards but we discovered that XJTAG goes so much farther. As a result, we have now built our development and test strategy for WMP100-based products around the XJTAG system.

"We selected XJTAG because implementation is lightning fast, we can easily customize tests for products from entry-level to high-end, and we can achieve high overall test coverage to guarantee the low ppm rates demanded by automotive applications. XJTAG also provides the freedom to develop a complete set of tests for any application within only a few days, using the graphical XJDeveloper environment."

In a typical Wavecom M2M module, the WMP100 processor, its configuration memory, and the Ethernet PHY are all connected to the boundary scan chain. XJTAG provides access to every pin, allowing design flaws or soldering faults to be accurately located. Functional communication tests can also be performed. Other devices connected to the WMP100, such as SRAM, Flash chips, A/D and D/A converters, a GPS or Zigbee chipset, CAN or Bluetooth modules, are also testable via XJTAG.
