It is possible to read data directly from a parallel bus. Each word is loaded by a signal for example /WE. In order to read this kind of word with a synchronous serial port it has to be converted in series and synchronized by a transmission clock. The solution presented in this document uses the clock signal coming from the DSP although an independent clock source could be implemented successfu

AN-927 Total Dose Testing of Advanced CMOS Logic at Low Voltage

Forecasted demand in energy is expected to double through 2030 and could outstrip supply. Furthermorewith increasing energy prices in history advancements in “clean/green technologies” is creating a wave ofopportunity. The last 2 to 3 decades of improvement have made alternative energies more attractive andless expensive. Solar industry is the fastest growing segment in the alternative ene

Wavelets have been developed to analyze the frequency components of a signal according to a scale. They provide more information than the Fourier transform for signals which have discontinuities or sharp spikes. This application report briefly presents the history of the wavelet starting with Fourier and describes the implementation of the wavelet transform using filter banks in the image pr

The input/output mini-driver (IOM) is the standard driver model for Texas Instruments' DSP/BIOS™ operating system. A driver built on this model can be easily and efficiently tied to the software interrupt (SWI) and task (TSK) threads that are used in the DSP/BIOS scheduler via the BIOS transport mechanisms of stream input/output (SIO) and pipe (PIP) modules. This application report shows how

Integrated circuit instrumentation amplifiers are used in a wide variety of applications such as medical instruments data acquisition systems and thermocouple signal conditioners. Many such applications require the gain to be switched to accommodate a variety of input signals and/or wide-ranging signal levels. The INA120 instrumentation amplifier meets this requirement as well as making it simple

This application note provides a simple circuit for adding undervoltage and overvoltage control to the TPS2490 and TPS2491 hotswap controllers.

This application report describes the development of a sensorless brushless DC motor phase advance actuator system based on the Texas Instruments (TI)(tm) TMS320C50 digital signal processor (DSP) and TMS320C50 evaluation module (EVM). Results show that applying a direct digital control methodology to the problem of controlled phase advance in a brushless DC machine substantially increases the effe

The bq20z70/90 evaluation module (EVM) and its corresponding evaluation software provides a rich and effective environment for examining the bq20z70/90 - a new advanced battery gas gauge. This application report covers this EVM and software with an emphasis on how to use it and what to expect. EVM board connections are discussed in detail and helpful hints are offered. For the evaluation softwar

The DS40MB200 is a new signal conditioning mux/buffer in TI’s high-speed product portfolio. It enables redundancy and acts as a repeater in high-speed backplanes and cables. It features programmable pre-emphasis and fixed input equalization enabling error free data links to 4 Gbps. It can also be used as a signal conditioning driver to provide equalization to FR4 board traces as well as cables s

This application report provides a step-by-step procedure for calculating buck converter efficiency and power dissipation at operating points not provided by the data sheet.

Load requirements often change during the project development phase affecting time to market schedules and budgets. Additionally higher efficiency may be needed to meet tight power budgets and higher output current devices typically have lower drain-to-source resistances. Fortunately many SWIFT(TM) DC/DC converters are pin compatible allowing the user to increase or decrease the output curr

This document describes how to configure the digital I/Os of the Texas Instruments (TI?) TMS320F240. The TMS320F240 DSP controller has 28 digital I/O pins. All 28 digital I/Os are multiplexed with oth
