Modern trends are driving the need for lower supply voltages across many system-level designs. As most processor voltage levels continue to decrease in the interest of achieving the lowest possible power consumption peripheral devices maintain a need for higher voltage levels creating potential for voltage discontinuities within a system. To remedy this mixed voltage system incompatibility a vo

This application report discusses the power consumption of the Texas Instruments TMS320DM368 digital media System-on-Chip (DMSoC). Power consumption on the DM368 device is highly application-dependent; therefore a spreadsheet that estimates power consumption is provided along with this document. To obtain good results from the spreadsheet realistic usage parameters must be entered (see Section 2

This document provides a guide for the use of the ePWM module to provide 0% to 100% duty cycle control and is applicable to the TMS320x280x family of processors.

This application report shows that increasing the slew rates of the winding currents in a bipolar stepper motor pushes the motor to deliver more torque at high speeds. Simple voltage drives L/R drives and chopper drives are explained. L/R drives and chopper drives achieve slew rates higher than those achieved by simple voltage drives. Finally an example chopper drive is presented.

This design note describes a linear regulator capable of maximizing the performance of digital systems. It uses a UC3833 precision linear controller. This IC includes all of the functions required to

This application report is intended for users designing an MPPT-based lead acid battery charger with the bq2031 battery charger. This report contains a design for charging a 12-A-hr lead acid battery

The DSP Hardware Designer's Resource Guide is organized by development flow and functional areas to make your design effort as seamless as possible. Topics covered include getting started, board desig

Asynchronous communication between a digital signal processor (DSP) and another device is a common system requirement. This application report discusses a software implementation of a universal asynchronous receiver and transmitter (UART) to enable asynchronous communication with minimal hardware overhead using the Texas Instruments (TI)(tm) TMS320C54x DSP. Topics covered include: - Asynchrono

The run-time support (RTS) library shipped with the code generation toolset includes functions such as fread() and fwrite() that can perform input/output (I/O) on host files. On some targets such as TMS320C2000? TMS320C3000? and TMS320C5000? the size of a char on the target (16 or 32 bits) differs from the size of a byte on the host (8 bits). The tools have two basic alternatives for dealing wi
