This application note provides a summary of differences between existing Sandstorm class devices and new Fury class devices in the Stellaris family of microcontrollers.
Ultra-low ESR capacitors such as ceramics are highly desirable because they can support fast-changingload transients and also bypass very high frequency noise coming from switching converter powersources which a linear regulator can not reject. However using ultra-low ESR capacitors on the output ofan LDO regulator requires that specific design changes be implemented to ensure loop stabili
This document describes each of the DSP/BIOS? performance benchmarks and the accompanying results followed by a technique used for calculating overall system performance or overhead. To help designers better analyze their system performance the methodology used has been detailed for obtaining each of the benchmarks along with the number of CPU cycles to execute each of the DSP/BIOS functions.

This application report discusses power consumption of the Texas Instruments TMS320C6452 Digital Signal Processor (DSP). Power consumption is highly application-dependent so a spreadsheet is provided to model power consumption for your applications.
This TPS659037 Operation With Higher Capacitive Loading application report addresses use-cases where external components demand a higher capacitive loading than the rating of the TPS659037 SMPS-outputs (57-μF maximum per phase). The specification of the device with a rating of nominal 47 μF and maximum of 57 μF holds true. Exceeding these values is at the risk of the user and requires thorough val
Charge pumps are dc/dc converters that use a capacitor instead of an inductor or transformer for energy storage. They are able to generate positive or negative voltages from the input voltage. The input voltage can be multiplied by some factor such as 0.5 2 3 and so on to generate the output voltage desired. Often charge pumps and all related parts (including those used for energy storage) ar
This application report is intended to help demystify the AIC27 example program that comes with the TMS320C5510? prototype board. The example program is intended to display some of the audio capabilities of the C5510? prototype board. Because it performs all these actions through header files and macros however it may seem unclear as to what is actually going on. This document clarifies what is
If you need more transducer excitation current than is available on a standard 4-20mA 2-wire current loop consider a 3-wire transmitter. A 2-wire 4-20mA transmitter uses the same two wires for signal and power. Part of the 4mA minimum loop current is used to power the transmitter circuitry. The remaining current can be used for transducer excitation. In some applications even the entire 4mA is no
Attention to layout is critical to the success of any battery management circuit board. The mixture of high-current paths with an ultralow-current microcontroller creates the potential for design issues that can be challenging to solve. This application report presents guidelines to ensure a stable and well-performing project.
The purpose of this design note is to explain how to use the different general digital output (GDO) pins for control and monitoring purposes. The focus is set on interfacing with a microcontroller unit (MCU) and is related to the CC1100 CC1101 CC1150 CC2500 and CC2550 devices.
This report discusses the theory and implementation of a 1200-bps splitband modem the Bell 212A/V.22. Throughout the report the terms Bell 212A and V.22 both refer to implemented modem. The report covers the following topics:- Modem Functional Blocks - Modem Transmitter - Modem Receiver- Modem Hardware Description - Analog Interface - Filters - Data Converter
As system bandwidths have increased an accurate estimate of the noise contribution for each element in the signal channel has become increasingly important. Many designers are not however particularly comfortable with the calculations required to predict the total noise for an op amp or in the conversions between the different descriptions of noise. Considerable inconsistency between manufactu
