This application report helps current and new users of the TRF7960 high-frequency RFID/NFC reader understand the differences between the TRF7960 and the TRF7960A devices. Understanding these differences in detail and applying this knowledge to application-specific requirements helps designers make informed decisions about whether or not a bill of materials change is needed.
The UCC3806 is a pin-for-pin-compatible BiCMOS replacement for the UC3846 and UC3856. However this design note explains how some functions in the UCC3806 are programmed differently. In particular the CUR LIM ADJ pin programs the maximum peak current for the current-sense amplifier. This function is completely compatible with that of previous ICs. The second function on this pin is the latch/non-
The OMAP5910 is a true system-on-a-chip device which consists of ARM925T MPU and C55X DSP cores. The device has many advanced power management modes that enable system designers to develop a very low-power multimedia communication device. This application note shows low-power design techniques and outlines the steps required to put the OMAP™ device in the lowest power consumption mode and
This application report describes methods for measuring code execution time of TMS470 and TMS570 microcontrollers. Besides the typical pin toggle approach, where the duration between two pin toggles i
The ADS603 is a 10MHz 12-bit analog-to-digital converter with a ±1.25V input range. Many applications call for a higher input range such as ±2.5V. A resistor divider can be used as an input attenuator to increase the input range. The OPA620 can be used to buffer the input attenuator for high-source-impedance applications. Suggested component values and measured performance results a
When transmitting to and receiving data from a processing engine such as the TMS320C25 digital signal processor, it is common to encounter problems when interfacing to asynchronous devices. This chapt
The TPS65381 is a multi-rail power supply designed to supply microcontrollers in safety critical applications such as those found in automotive functions. The device supports Texas Instruments’ TMS570LS series 16/32-Bit RISC Flash MCU and other microcontrollers with dual-core lockstep (LS) or loosely coupled (LC) architectures.The TPS65381 integrates multiple supply rails to power the MCU CA
This application report provides background information, general equations, and instructions for proper use of the Texas Instruments TAS57xx series Dynamic Range Control (DRC). Topics include I2C con
The Texas Instruments (TI)(tm) TMS320F241 TMS320C241 and TMS320F243 digital signal processor (DSP) controllers contain an on-chip Control Area Network (CAN) module. This module is a FullCAN controller (Specification 2.0B). This application report describes the TMS320X241/3 CAN module. Software examples are included for different modes of operation of the on-chip CAN module along with an applicati
Bluetooth pairing usually involves some level of user interaction to confirm the identity of the user and/or the devices themselves. There are many pairing mechanisms available across the versions of
Designing high-resolution detection circuits using photodiodes presents considerable challenges because bandwidth gain and input-referred noise are coupled together. This application note reviews the basic issues of transimpedance design provides a set of detailed design equations explains those equations and develops an approach to easily compare potential solutions.
This application report describes how to communicate with the Hercules™ UART bootloader. The UART bootloader is a small piece of code that can be programmed at the beginning of Flash to act as an application loader as well as an update mechanism for applications running on a Hercules Cortex™-R4 based RM42 microcontroller.
