It is possible to read data directly from a parallel bus. Each word is loaded by a signal for example /WE. In order to read this kind of word with a synchronous serial port it has to be converted in series and synchronized by a transmission clock. The solution presented in this document uses the clock signal coming from the DSP although an independent clock source could be implemented successfu

Temporary invalid data in the SBS.FullChargeCapacity() register of the bq20z80-V1.01 could occur under rare conditions. This application report describes those conditions and the solutions.

7-W Single Stage PFC LED Lighting Design with TRIAC Dimming Written in China

The software demonstrates real-time D1 JPEG encoding and decoding of images on a DM642 EVM. The JPEG standard pertains to compression of still images. Performing JPEG at the rate of 30 frames per second in isolation as individual images is considered motion JPEG (MJPEG). The demonstration uses:

• JPEG encoder library optimized for a DM642 EVM capable of real-time D1 encoding
• JPEG dec

With operating frequencies exceeding 300MHz Texas Instruments line of monolithic and hybrid currentfeedback operational amplifiers have become an attractive option for the RF (and IF) design engineer.Typical operational amplifier specifications do not however include many of the common specificationsfamiliar to RF engineers. To help the designer exploit the many advantages these amplifier

Portable electronics with long battery lives are unquestionably more marketable. Power consumption of the microprocessor can be reduced by lowering the internal clock frequency and/or even more by lowering the core supply voltage. Dynamic voltage scaling (DVS) is used to reduce core supply voltage to minimize power consumption. This application note explains how to implement DVS using a TPS6220

Support of Multiple Li-Ion Chemistries With Impedance Track(TM) Gas Gauges

IEEE Std 1394b-2002 specification allows the use of optical media for longer distances at higher speeds. The use of optical media provides galvanic isolation lower electromagnetic interference (EMI) and lower interference from the environment.Interfacing 1394.b physical-layer devices (PHYs) may require additional components depending on the type of fiber-optic transceiver (FOT) selected. Th

The bq2000 charger can be used to charge Li-Ion, NiCd, or NiMH batteries. It uses three charging modes, the pre-charge, fast charge, and termination mode. It detects the battery chemistry type during

The LaunchPad™ ACTBP host application is the firmware running on the MSP430 LaunchPad development kit to demonstrate the Audio Player Recorder Framework for the C5000™ Audio Capacitive Touch BoosterPack.

A Memory Protection Unit (MPU) is a module used to modify the memory types and attributes as defined in a processor?s memory ordering model. The MPU is specific to each core in the system and can only

The ADS1202 is a precision 80dB dynamic range delta-sigma (ΔΣ) modulator operating from a single +5V supply. The differential inputs are ideal for direct connections to transducers or low-level signals. With the appropriate digital filter and modulator rate the device can be used to achieve 15-bit analog-to-digital conversion with no missing codes. This application note describes ho

Power-on-Ethernet is an emerging technology that allows an existing Ethernet connection to carry both data and power. However today's powered-device (PD) designers face a dilemma - not all Ethernet connections are wired for power. To operate with these legacy connections a PD can use a wall adapter but this capability must be designed into the PD.
