SPI Bootloader for Hercules TMS570LS04X MCU

Texas Instruments

This application report describes how to communicate with the Hercules™ serial peripheral interface (SPI) bootloader. The SPI bootloader is a small piece of code that can be programmed at the beginning of Flash to act as an application loader as well as an update mechanism for applications running on a Hercules Cortex™-R4 based TMS570LS04x microcontroller.

TLV2370/71/72/73/74/75 EMI Immunity Performance (Rev. A)

Texas Instruments

The electromagnetic interference (EMI) rejection ratio, or EMIRR, describes the EMI immunity of operational amplifiers. An adverse effect that is common to many op amps is a change in the offset voltage as a result of RF signal rectification. An op amp that is more efficient at rejecting this change in offset as a result of EMI has a higher EMIRR and is quantified by a decibel value.

Precision Absolute Value Circuits

Texas Instruments

You can build a precision absolute value circuit using two op amps and two precision resistors. If you use an op amp and an IC difference amplifier no user supplied precision resistors or resistor adjustments are required. Circuits shown are suitable for precision split supply operation and for single-supply operation. When used with a rail-to-rail op amp the single supply circuit can approach a

Implementing a 60-W End-to-End PoE System

Texas Instruments

Specialized applications such as WiMax base stations may require more than 50 W of power, but the current IEEE 802.3at standard defines 25.5-W, two-pair systems. This application report presents a non

Prototyping the TI TMS320C40 to the Cypress VIC068/VAC068 VME Interface

Texas Instruments

The VIC068/VA068 is designed to interface with the Motorola 68000 microprocessor family so interfacing it to the TMS320C40 digital signal processor (DSP) requires a logic simulation or configurable prototype. This document focuses on the details of the hardware design and the programmable logic source code interfacing the VIC068 to the TMS320C40 32-bit parallel DSP. It provides the details on the

Interfacing Dolphin to an External System Microcontroller (Rev. B)

Texas Instruments

This application note discusses the hardware and firmware implementation details of interfacing an external system (application) microcontroller to the Dolphin chipset. The system microcontroller performs all the application and system level tasks and is needed to set up the operation of the Dolphin chipset.

Texas Instruments has developed evaluation software that interfaces to the Dolphin chipset through hardware UART interface of the DBB03A digital baseband ASIC. However in real end applications, an external system microcontroller is needed to emulate the features of the Dolphin evaluation software. This evaluation software was purely developed for demo purposes. Any catalog low-cost microcontroller can be interfaced to the Dolphin chipset as long as they follow the Dolphin host interface protocol (SWRA043) for communication.

Texas Instruments recommends its ultra-low power MSP430 series of microcontrollers to interface with Dolphin. Specifically the firmware in this application note was developed for MSP430F1121A microcontroller.

Using the TPS62125 in an Inverting Buck-Boost Topology (Rev. B)

Texas Instruments

The TPS62125 is a DCS-Control™ topology synchronous buck dc-to-dc converter designed for low-power applications. It features a wide operating input voltage range from 3 V to 17 V, 300-mA output current, and adjustable output voltage of 1.2 V to 10 V. This device is well-suited for applications such as ultra lowpower microprocessors, energy harvesting, and low-power RF applications. Moreover, the TPS62125 can be configured in an inverting buck-boost topology, where the output voltage is inverted or negative with respect to ground. This application note describes the TPS62125 in an inverting buck-boost topology for use in low current negative rails for operational amplifier or optical module biasing and other low-power applications.
