This reference design is presented to help application designers and others who are trying to use the MSP430 in a system with an input voltage in the range of 1.8 V to 5.5 V, and who must increase the
Many members of the Stellaris® family of microcontrollers provide system designers with a great deal of control over the placement and selection of peripheral module signals that are alternate fun
This application brief presents phase-noise data taken on Texas Instruments CDC7005 jitter cleaner and synchronizer PLL. The phase noise performance of CDC7005 depends on thephase noise of the reference clock the voltage-controlled crystal oscillator (VCXO) clockand the CDC7005 itself. This applications brief shows the phase noise performance of the CDC7005 clock synthesizer at the most popula
TI frame transfer charge coupled devices (CCD) image sensors can be used in a wide variety of applications with the following topology options: one to three serial registers transfer gates a multiplexer separate reset lines center clearing drains and electron-hole recombination or lateral-overflow-drain antiblooming protection. This document describes the timing design for the TI frame transf
A low-side, current-sensing resistor in a fast-charge control circuit generates a small voltage drop between the low side of the battery pack and ground. This drop is not a problem in most cases; howe
This application report explains a technique that uses two MSP430™ microcontrollers to expand the maximum number of LCD segments that can be driven with a single controller. Additional benefits of the technique include increases in available memory data storage (RAM) and I/O control lines. These benefits are realized without the need for an external LCD driver circuit. The use of a second
The development of realistic predictions to assist the power supply engineer during the control loop design process is facilitated in this application report by appropriate small-signal and bode plot analysis the validity of which is verified through simulation results.
Sources of noise generation are pervasive in contemporary industrial applications. Unwanted noise presents one of the major problems in measuring power or protecting circuits in such an environment. Knowing the characteristics and understanding the behavior of noise sources are valuable to designers and users of electronic circuits. The first part of this report defines some fundamental concepts o
The dual-band handset market is expanding very rapidly due to the increase in customers requiring roaming capability. The customer also demands that handsets have an increase in features while keeping
Voltage-monitoring circuits are firmly established in microcomputer systems. These circuits perform system initialization which includes circuit reset and they monitor the supply voltage during operation. When combined with watchdog circuits they monitor the proper functioning of a device in safety-relevant circuits. This report describes the new TPS312x series of voltage-monitoring integrated
The new GCC compiler for MSP low-power microcontrollers (MSP430-GCC-OPENSOURCE) conforms to the MSP Embedded Application Binary Interface (EABI) (see SLAA534). This allows GCC to interoperate with the proprietary TI compiler. For example assembly functions can be written in the same way and libraries that are built with one compiler can be used as part of executables built with the other compile
