This application report describes the features and operation of the Texas Instruments (TI™) TMS320F240 digital signal processing (DSP) external memory interface. First a simple interface example is provided to show the considerations for connecting SRAMs to the 'F240. Following this the basic operation of a single read and a single write access is described to provide an understanding of t
This document discusses the power consumption of the Texas Instruments TMS320C6412 digital signal processor (DSP). Power consumption on these devices is highly application dependent so a spreadsheet is provided to model power consumption for a user's application. To get good results from the spreadsheet realistic usage parameters must be entered. The low core voltage and other power design optim
The Texas Instruments RF430FRL15xH ISO/IEC 15693 NFC Sensor Transponder is an NFC Tag Type 5 device operating at 13.56 MHz (HF band). Depending on the application communication distance requirements the antenna geometry can be adjusted. The device gives the flexibility to be used in combination with various antenna geometries. The scope of this document is a short practical guidance on antenna de
This application report describes how to set the Microsoft? Windows? environment variables for correct I²C™ operation of the TAS5715EVM evaluation module (EVM). The proper environment vari
The C64X+ Megamodule supports a wide variety of internal memory configurations by allowing the L1 program and data memory (L1P and L1D) to set as cache only SRAM only or a mixture of cache and SRAM. In addition the C64x+ Megamodule provides new system functionality including: cache freeze Internal DMA (IDMA) bandwidth management and memory protection. This document discusses the enhancements
The TMS320TCI648x devices introduce a newly designed Enhanced Direct Memory Access (EDMA3). The EDMA3 has many new features that improve system performance and enhance debugging capabilities. This doc
This thermal application report provides guidelines for the optimal board layout to achieve the best thermalresistance for exposed packages. The thermal resistance between junction-to-ambient (θJA) is highlydependent on the PCB (Printed Circuit Board) design factors. This becomes more critical for packageshaving very low thermal resistance between junction-to-case such as exposed pad TSSOP
Memory modules have long been a system designer's trump card. Modules, in addition to the traditional space savings, allow ease of implementation, known operating performance, flexible density options
Grid connected applications require an accurate estimate of the grid angle to feed power synchronously to the grid. This is achieved using a software phased-locked loop (PLL). This application report
The fundamental challenge of power supply design is to realize simultaneously two conflicting objectives: good electrical performance and low cost. The UC3842/3/4/5 control ICs are integrated pulse-width modulators (PWMs). These inexpensive IC controllers provide all the performance advantages of current-mode operation. In addition the UC3842 series is optimized for efficient power-sequencing of
The bq208x (bq2083 bq2084 and bq2085) products are high-precision advanced gas gauge products for battery monitoring and management. Because the current signal ismeasured through a small sense resistor (< 20 m?? to minimize power loss compensation for the ADC input offset is critical for the accuracy of the measurement. This application note discusses common issues associated with board offse
The Stellaris® on-chip clock failure detection circuitry allows a microcontroller to respond appropriately if the main crystal oscillator stops functioning. This capability can be extended to situations in which the crystal oscillator fails due to an open or short circuit.
Radio networks such as those used by emergency services or public transportation transmit across a narrow bandwidth thus requiring low transmission rates. This document describes the channels and transmission method of these existing networks. Applying complex algorithms to code images allows development of a source codec. This codec uses multiple TMS320C40 32-bit parallel digital signal proces
