Introduction to the Controller Area Network (CAN) (Rev. A)
Texas InstrumentsA controller area network (CAN) is ideally suited to the many high-level industrial protocols embracing CAN and ISO-11898:1993 as their physical layer. Its cost, performance, and upgradeability provid
Built-In Self-Test (BIST) Using Boundary Scan (Rev. A)
Texas InstrumentsThe IEEE standard boundary scan framework and four-wire serial testablity are having a positive impact on testing all levels of electronic assembly. The two form a basis from which other techniques are developed to facilitate testing of chips and systems. This document shows how existing architectures can be modified to conform to IEEE 1149.1 architecture. A boundary BIST approach is described and
AVC Logic Family Technology and Applications (Rev. A)
Texas InstrumentsTexas Instruments (TI?) announces the industry?s first logic family to achieve maximum propagation delays of less than 2 ns at 2.5 V. TI?s next-generation logic is the Advanced Very-low-voltage CMOS (AVC) family. Although optimized for 2.5-V systems AVC logic supports mixed-voltage systems because it is compatible with 3.3-V and 1.8-V devices. The AVC family features TI?s Dynamic Output Control (
