Configuring the bq78PL114 Cell Count (Rev. A)
Texas InstrumentsConfiguration of the bq78PL114 to a custom series and parallel cell arranged pack is accomplished outside parameter tabs in bqWizard™ or the .ppcsv parameter configuration file. It is easy to set by loading an appropriate .tmap file to the device. This application report describes loading the .tmap file some considerations for the parallel cell count configuration and how to simply edit the .tm
High-Voltage Signal Conditioning for Differential ADCs
Texas InstrumentsAnalog designers are frequently required to convert high-voltage signals to levels acceptable to low-voltage data converters with differential inputs. This paper describes solutions for this common task using modern amplifiers and typical power supplies. Three examples of conditioning ±10V bipolar signals for low-voltage analog-to-digital converters (ADCs) are shown: a single-supply design
TMS320TCI TCP2 Channel Density
Texas InstrumentsTurbo decoder lies at the heart of all of the third-generation (3G) wireless standards. The turbo coprocessors (TCP2) are programmable peripherals used to decode turbo codes. It is integrated into Texas Instruments TMS320TCI648x Digital Signal Processor (DSP). This application report gives the channel density data for TCP2 under various conditions the CPU load for pre-processing TCP2 input data i

Improving System Interrupt Management Using the PCF8574 and PCF8574A I/O Expande
Texas InstrumentsIn today?s complex embedded computing and data-communication systems interrupts areused extensively to service peripheral devices. However because of the pin-numberlimitation on packages most microprocessors have only one or two interrupt lines.Consequently several devices usually are connected to the same interrupt line. Thedrawback to this configuration is that the overhead process
I2C communication with the TMS470R1x
Texas InstrumentsThis application note describes how to configure the internal registers of a TMS470R1x (TMS470) device for setting up inter-integrated communication (I2C) with an industry standard 24LC00 I2C memory device. This application report assumes the reader is familiar with the I2C protocol and is meant to supplement the TMS470 Inter-Integrated (I2C) Reference Guide (literature number SPNU223) and the dev
