June 26, 2002 - National Semiconductor (NYSE:NSM) today announced the availability of the SCANSTA101, the latest in a series of products designed to dramatically improve testability in base stations, switches, multiplexers and other complex telecom and datacom systems.
National?s SCANSTA101 is a system-level turnkey solution that reduces costs and simplifies testing in printed circuit boards and embedded systems designed using industry-standard IEEE 1149.1 protocols. SCANSTA101 also enables faster, easier configuration of Complex Programmable Logic Devices (CPLD) and embedded FLASH memories.
?National?s new SCANSTA101 enables JTAG test, programming, and configuration access in complex systems. The SCANSTA101 eliminates most of the overhead when interfacing an embedded test processor to the serial IEEE 1149.1 bus,? said Brian Stearns, Marketing Manager for System Test Access Products. ?This product extends National?s leadership position and enables our customers to implement time and money-saving embedded test features in their products.?
Key Features and Benefits
National?s SCANSTA101 is a system-level IEEE 1149.1 compliant support device that converts parallel test data into an 1149.1 compliant bit stream without the overhead necessary for vector conversion. The device is optimized for embedded test applications where test features are built into the system. The SCANSTA101 features an on-board memory that speeds testability by eliminating process bottlenecks when converting data from parallel to serial formats, and back to parallel.
SCANSTA101 utilizes a generic asynchronous processor interface that is a simple to use and is compatible with a wide range of processors and clock frequencies. The SCANSTA101 is supported by National Semiconductor?s SCANEASE rev 2.0. SCANEASE is a command line utility that converts Serial Vector Format (SVF) test vectors from ASCII to a highly efficient binary embedded vector format EVF2. SCANEASE adds the functionality of the SCANSTA101 and IEEE1149.1 into embedded test vectors.
SCANSTA101 also features a wide, 16-bit data interface (IP scalable to 32-bit) that allows faster throughput of data. Flexible dual-port memory addressing may be accessed by either the Parallel Processor Interface or the 1149.1 master. Load-on-the-Fly (LOF) and pre-load operating modes are supported, allowing for flexible system design. A 32-bit Linear Feedback Shift Regulator (LFSR) at the Test Data In (TDI) port compresses test results, enabling a quick evaluation of software programming or test results. SCANSTA101 operates at a 3.3-volt power supply and is tolerant of 5-volt input-output, which allows its use in mixed-voltage systems. It also operates in power down mode, allowing hot insertion.
Pricing and Availability
National?s SCANSTA101 is available in a 49-pin BGA package (7mm x 7mm, 0.8mm pitch), or as an Intellectual Property (IP) model for embedding into Very Large Scale Integrated (VLSI) chips. SCANSTA101 is available for $9.00 each in 1000-unit quantities. More information is available at the following web site: http://www.national.com/scan
