Often times, embedded processors must be programmed in situations where JTAG is not a viable option for programming the target device. When this is the case, the engineer must rely on some type of se

This application report describes how to interface the DAC8574 digital-to-analog converter to the MSP430F449 mixed signal microcontroller.

In this application report we discuss the hardware and software interface of the TLV1562 10-bit parallel-output analog-to-digital converter (ADC) to the TMS320C54x digital signal processor (DSP). The hardware interface board or evaluation module (EVM) consists of the TLV1562 10-bit ADC a THS5651 10-bit parallel-output communication digital-to-analog converter ((CommsDAC (TM)) and a TLC5618A s

FRAM is a nonvolatile embedded memory technology and is known for its ability to be ultra-low power while being the most flexible and easy-to-use universal memory solution available today. This application report is intended to give new FRAM users and those migrating from flash-based applications knowledge on how FRAM meets key quality and reliability requirements such as data retention and endura

TUSB2136/TUSB3210 Firmware Debugging Guide

This application report examines the thermal performance of different layout techniques for the TPS5461x family of 6-amp synchronous buck regulators. The TPS5461x family consists of the TPS54610 TPS54611 TPS54612 TPS54613 TPS54615 and the TPS54616. The TPS54610 has an adjustable output voltage while the output voltages of the other devices in this family are fixed. This application note is a

The TMS320 DSP C compilers produce several relocatable blocks of code and data when C code is compiled. These blocks are called sections and can be allocated into memory in a variety of ways to conform to a variety of system configurations. The .bss section is used by the compiler for global and static variables. It is one of the default COFF sections that is used to reserve a specified amount of

This application report describes how the G.723.1 Dual-Rate Speech Coder has been implemented on the TMS320C62x digital signal processor (DSP). Beyond the use of the ?C62x intrinsic functions the application report includes specific changes required to allow this coder to operate in a real-time system with other speech coders. Also reported is information on several optimization techniques used t

The TMS320C6472/TMS320TCI6486 has six C64x+ Megamodule cores that run at 500 MHz 625 MHz or 700 MHz. This document has been written based on the performance of the C6472/TCI6486 device running at 500 MHz and 625 MHz. Each megamodule has 32KB of L1D SRAM 32KB of L1P SRAM and 608KB of LL2 SRAM and all six cores share 768KB of SL2 SRAM. A 32-bit 533-MHz DDR2 SDRAM interface is provided on the DSP

This application report contains implementation instructions for the DDR2 interface contained on the TMS320C6454/5 digital signal processor (DSP) device. The approach to specifying interface timing for the DDR2 interface is quite different than on previous devices.

The previous approach specified device timing in terms of data sheet specifications and simulation models. The system designer was

This application report discusses how to use the UBL to load a custom application developed on Code Composer Studio™ to DDR and then to execute the application from DDR. The UBL, sfh tool, and c

Programming Audio Power Up/Down on TSC210x and TLV320AIC26/28

AN054 -- Anaren balun optimized for CC2420

This application report is provided as a supplement to the DRV8828, DRV8829, and DRV8840 product data sheets. It details the hardware implementation of the DRV8828/29 and an MSP430F2112 microcontrolle

This reference design was created to help those needing to power the Marvell PXA270 and doing so by implementing a highly simplistic and efficient design that uses the TPS65021 power management unit.

The primary bus of the TMS320C30 has 24 address lines, which allows addressing of up to 16 megawords of memory. The expansion bus has 13 address lines, which allows addressing 8 Kwords. Using the tech

The Texas Instruments bq2403x family of linear charge regulators were originally designed to charge single-cell Li-ion batteries from an AC adapter or USB port. However, these ICs also lend themselves

Four steps are required to set the TMS320 DSP interrupts: create a interrupt service routine, initialize the vector table and set the memory map, enable the interrupts in the CPU, and enable the inter
