TMS3705 Passive Antenna Solution
Texas Instruments
The Texas Instruments low-frequency transponder technology provides the possibility to use a simple passive antenna in combination with various antenna cable lengths. This solution significantly reduces system costs because the active part of the transceiver can be added to the already existing host system e.g. the body control module (BCM) of a vehicle.

Automotive 200-VA High Frequency Inverter Design
Texas Instruments
This design presents a low-cost: small size: robust 200-VA DC to AC inverter based on TI’s MSP430 and UCD8220-digitally managed push-pull controller. It is targetted towards car inverters and small-segment inverters for commercial applications. In this design: UCD8220 is used for a boost stage to get 250-V DC from a 12-V battery. The MSP430 acts as a host controller and provides a 100-kHz clock to UCD8220 and drives for output DC-AC bridge. This inverter has a peak efficiency of 90% and has natural cooling and does not require a fan for cooling.

The short and long term reliability of National Semiconductor's interface circuits like any integrated circuit is very dependent on its environmental condition. Beyond the mechanical/environmental factors nothing has a greater influence on this reliability than the electrical and thermal stress seen by the integrated circuit. Both of these stress issues are specifically addressed on every inter

The ADuCRF101 is a fully integrated, data acquisition solution that is designed for low power, wireless applications. It features a 12-bit analog-to-digital converter (ADC), a low power ARM Cortex?-M3 processor, a 862 MHz to 928 MHz and 431 MHz to 464 MHz RF transceiver, and Flash?/EE memory. The ADuCRF101 is packaged in a 9 mm ? 9 mm LFCSP.The data acquisition section consists of a 12-bit SAR ADC. The six inputs can be configured in single-ended or differential mode. When configured in single-ended mode, they can be used for ratiometric measurements on sensors that are powered, when required, from the internal low dropout regulator (LDO). An internal battery monitor channel and an on-chip temperature sensor are also available.This wireless data acquisition system is designed to operate in battery-powered applications where low power is critical. The device can be configured in normal operating mode or different low power modes under direct program control. In flexi mode, any peripheral can wake up the device and operate it. In hibernate mode, the internal wake-up timer remains active. In shutdown mode, only an external interrupt can wake up the device.The ADuCRF101 integrates a low power ARM Cortex-M3 processor. It is a 32-bit RISC machine, offering up to 1.25 DMIPS peak performance. The ARM Cortex-M3 processor also has a flexible 14-channel direct memory access (DMA) controller that supports communication peripherals, serial peripheral interface (SPI), UART, and I2C. Also provided on chip are 128 kB of nonvolatile Flash/EE memory and 16 kB of SRAM.A 16 MHz on-chip oscillator generates the system clock. This clock can be internally divided for the processor to operate at a lower frequency, thus saving power. A low power, internal 32 kHz oscillator is available and can be used to clock the four timers, as follows: two general-purpose timers, a wake-up timer, and a system watchdog timer.A range of communication peripherals can be configured, as required, in a specific application.
