TRF7960 Antenna Matching for the TRF7960 RFID Reader

This document discusses thermal analysis and heat sink selection for the Texas Instuments (TI™) TMS320C6x digital signal processor (DSP). A simplified approach is offered to select a heat sink that matches a particular operating environment. Examples are included to demonstrate the method for selecting a heat sink for a typical design.

CAN protocol imposes rather stringent requirements on its timing source which are generally met by the provision of an external quartz crystal/oscillator. The TMS320C2803x/TMS320F2806x series of microcontrollers have an on-chip zero-pin oscillator that needs no external components. This application report describes how to use the CAN module with this oscillator to operate at the maximum bit rate

The FlashBurn utility is a Windows program that works along with Code Composer Studio and an FBTC (FlashBurn Target Component) program to burn data and programs into the FLASH memory of a DSP target b

The TUSB6250 bootcode is a start-up code stored as a ROM image within the TUS6250 device. An embedded microcontroller starts executing this code after power-on reset. Once the code is running it loads application firmware from either an external memory device or the USB host controller. After the code has finished downloading the bootcode releases its control to the application firmware.This

The CS4231 is a 16 bit stereo codec chip with various features, such as multiple analog inputs and outputs, mixing, and gain capabilities, that make them ideal for computer sound applications. The digital interface consists of a parallel 8-bit bus and is meant to directly connect to a PC (ISA/EISA) interface. Since it is a glueless interface to a PC bus, it looks a bit different from a TMS320C5x or other TMS320 DSPs with asynchronous memory interface.

This Application Note describes an optimum interface to a TMS320C5x DSP. Note that other TMS320 DSP asynchronous buses are very similar and most of the interface described here will also apply to any TMS320 DSP system. In this implementation the TMS320C5x and codec share the same bus with SRAM. This tradeoff keeps pin count and thus cost down, at the cost of performance. A separate codec bus mapped into the DSP's memory or I/O space would make the system more efficient and is briefly described at the end of this Application Note along with other system considerations.

This application report presents four system topologies that can be used to fully implement a portable power management system solution using the bqSWITCHER™. Test results and the advantages and issues of each topology are discussed.
