The flash controller of the MSP432 MCUs is a very powerful and intricate peripheral that has a robust programming model and feature-rich implementation. With a proper software layer, the programmer is able to abstract out the complexities of the flash controller's programming model and keep application code free of any flash controller overhead. Additionally, executing DriverLib from ROM enables the user to not have to worry about any significant boundary requirements when verifying flash operations and changing flash banks into special read modes.

Ratiometricity is a common approach for measuring analog-sensor signals for the purpose of conditioning and standardizing the signal for proper operation with an industrial control system. In the context of linear-variable differential-transformer (LVDT) signal conditioning, ratiometric measurement has a specific meaning. In this article, ratiometric measurement is described in general and also in the context of LVDT-sensor signal conditioning in three different stages of the signal chain.

The INA117 is a monolithic difference amplifier with the unique ability to accept up to ±200V common-mode input signals while operating on standard ±15V power supplies. Using on-chip hig

Well-designed electronic systems only use as much power as they need to for each state of operation. While this is crucial for battery-powered systems, AC powered systems also benefit from minimizing power, since that reduces heat dissipation, maximizes the product lifetime, and conserves electricity.

Low-power modes work best when they seamlessly transition to a higher power mode without the user taking separate action. This full automation will be paramount to smart systems of the future. When the power mode can change based on some mechanical movement occurring, Hall effect sensors are often a suitable technology to be used.

Several features commonly used in microcontroller (MCU) designs, such as external EEPROMs, SHA-1 authenticators, temperature sensors, digital switches, and battery system monitors, use a single bidirectional line to transfer data between itself and a master device. Commonly referred to as 1-wire or SDQ single-wire serial interfaces, this communication peripheral reduces the number of physical hardware connections required while adhering to a protocol that can be easily achieved with MSP430 MCUs acting as the function's master. Commands can be basic enough to operate with the MSP430FR2000 MCU, which contains 512 bytes of main memory, or expanded to service a multitude of operations and slave devices. A code example that demonstrates the initialization of such an interface is below. To get started, download project files and a code example demonstrating this functionality.

The 16-bit MSP430 and the 32-bit SimpleLink MSP432 microcontroller (MCU) families complement each other in low-power and performance. The goal of this migration guide is to help developers accurately assess the effort to migrate an existing application from the 16-bit MSP430 to the 32-bit SimpleLink MSP432 Arm platform if they so choose to. Ultimately, the migration guide is built to help derive a migration strategy with complete hardware and software coverage that properly migrates the existing application without introducing bugs due to platform differences while still taking advantage of the unique features or performance improvements that the 32-bit MSP432 devices bring.

The DRV2700 is a high-voltage piezo driver with an analog input. This device is one of the many haptic feedback drivers that Texas Instruments offers. One design challenge many customers face using the DRV2700 is the analog input. Generating an analog input signal can burden the processor and be undesirable. This application note addresses this challenge and provides a solution.

Incremental rotary encoders transduce rotational movement into electrical signals. Unlike absolute encoders that measure angle, incremental encoders generate high/low pulses as turning occurs.

Applications include computer mouse wheels, fluid flow meters, knobs, wheel speed sensors, stepper motor feedback for detecting missed steps, and brushed DC motor sensors for automotive windows, sunroofs, seats, and mirrors.

Medical and industrial ultrasound systems use focal imaging techniques to achieve imaging performance far beyond a single-channel approach. Ultrasound images are created by sending high voltage pulses into human tissue. The sound generated by these pulses echoes off of the tissues at varying amplitudes depending on factors such as depth within the body and type of tissue. Ultrasound technology is manufactured to measure the voltage magnitude of these echoes as they are collected at the receiver. These voltages are ultimately recorded and displayed in an image that tells what kinds of surfaces the pulses are passing through.

This application note discusses the importance of clocking in Ultrasound and also illustrates how some key TI devices achieve very low end to end jitter and phase noise. The application note also demonstrates how various stages have very low additive jitter.

This application note describes how to design a high reliability rotary switch or encoder using a Dialog GreenPAK. This switch design is contactless, and therefore ignores contact oxidation and wear. It is ideal for use outdoors where there is long term moisture, dust, temperature extremes, etc.

Dialog GreenPAK SLG46537: The GreenPAK CMIC provides all the circuit functions for this design. It generates a signal (EVAL) for improved signal to noise, receives inputs from each sector pad of the rotary switch, and interprets each sector pad using the Asynchronous State Machine(ASM) to guarantee only one switch selection.

Galvanically isolated interfaces are a common requirement within industrial devices for safety reasons. In this type of application, a digital isolator is used to galvanically isolate an MCU from a communication transceiver or an ADC.

Digital isolators work at two power domains, using an isolated DC power supply in one domain. The low DC voltage for isolated power domain could be achieved with a small and simple push-pull converter. The push-pull converter is a transformer-isolated topology using two transistors switching in complementary mode.

This application note will present a low cost and low power DC/DC push-pull converter based on the Silego GreenPAK SLG46108 device. The following sections will show how to:

• Generate a complementary PWM with dead time using the programmable delay block.
• Generate a start-up sequence using a pipe-delay block.
• Obtain multiple clock frequencies via an internal oscillator.
