Using the TMS320DM647/DM648 Bootloader (Rev. D)
Texas InstrumentsThis document describes the functionality of the TMS320DM647/DM648 ROM bootloader software. The ROM bootloader resides in the ROM of the device beginning at ROM address 0x00100000. The ROM boot loader (RBL) implements methods for booting in the listed modes. It reads the contents of the BOOTCFG register to determine boot mode and performs appropriate commands to effect boot of device. If an improp

Stack Mode Initialization/Reset on the TMS320C55x DSP
Texas InstrumentsThis document contains information and examples of how to initialize and use the several stack modes that are available on the TMS320C55x? DSP.
What Designers Should Know About Data Converter Drift
Texas InstrumentsExactly how inaccurate will a change in temperature make an analog-to-digital or digital-to-analog converter? As designers are well aware, a 12-bit device may provide a much lower accuracy at its oper
Clamping Amplifier Tracks Power Supplies
Texas InstrumentsClamping amplifiers limit signal magnitude to protect following circuitry from input overload. The clamping amplifier shown here produces limit levels that track the power supply levels selected in an

Achieving Maximum Speed on Parallel Buses With Gunning Transceiver Logic (GTLP)
Texas InstrumentsThis application report compares two approaches for synchronous bus-system designs. The focus of the report is the comparison of a system using central-synchronous system clock (CSSC) with a system operated with a source-synchronous system clock (SSSC).The basic characteristics of lines key factors that influence the bus line delay and the impedance of bus lines are described.The theoretical
Understanding LDO Dropout
Texas InstrumentsNot all low dropout (LDO) linear regulator data sheets provide the voltage dropout information needed for all applications. This application report shows a designer how to use an LDO data sheet's specified dropout performance to determine the dropout voltage at other operating conditions.
Migrating From MSP430F16x to MSP430F261x (Rev. A)
Texas InstrumentsThe purpose of this application report is to facilitate the migration of MSP430F167/F168/F169/F1610/F1611/F1612-based designs to the MSP430F261x device family. In the course of this application report
