The ADuCM360 is a fully integrated, 3.9 kSPS, 24-bit data acquisition system that incorporates dual high performance, multichannel sigma-delta (Σ-Δ) analog-to-digital converters (ADCs), a 32-bit ARM Cortex™-M3 processor, and Flash/EE memory on a single chip. The ADuCM360 is designed for direct interfacing to external precision sensors in both wired and battery-powered applications. The ADuCM361 contains all the features of the ADuCM360 except that only one 24-bit Σ-Δ ADC (ADC1) is available.

The ADuCM360/ADuCM361 contain an on-chip 32 kHz oscillator and an internal 16 MHz high frequency oscillator. The high frequency oscillator is routed through a programmable clock divider from which the operating frequency of the processor core clock is generated. The maximum core clock speed is 16 MHz; this speed is not limited by operating voltage or temperature.

The microcontroller core is a low power ARM Cortex-M3 processor, a 32-bit RISC machine that offers up to 20 MIPS peak performance. The Cortex-M3 processor incorporates a flexible, 11-channel DMA controller that supports all wired communica-tion peripherals (SPI, UART, and I2C). Also integrated on chip are 128 kB of nonvolatile Flash/EE memory and 8 kB of SRAM.

The analog subsystem consists of dual ADCs, each connected to a flexible input mux. Both ADCs can operate in fully differential and single-ended modes. Other on-chip ADC features include dual programmable excitation current sources, diagnostic current sources, and a bias voltage generator of AVDD_REG/2 (900 mV) to set the common-mode voltage of an input channel. A low-side internal ground switch is provided to allow power-down of an external circuit (for example, a bridge circuit) between conversions.

The ADCs contain two parallel filters: a sinc3 or sinc4 filter in parallel with a sinc2 filter. The sinc3 or sinc4 filter is used for precision measurements. The sinc2 filter is used for fast measure-ments and for the detection of step changes in the input signal.

The devices contain a low noise, low drift internal band gap ref-erence, but they can be configured to accept one or two external reference sources in ratiometric measurement configurations. An option to buffer the external reference inputs is provided on chip. A single-channel buffered voltage output DAC is also provided on chip.

The ADuCM360/ADuCM361 integrate a range of on-chip peripherals, which can be configured under microcontroller software control as required in the application. The peripherals include UART, I2C, and dual SPI serial I/O communication controllers; a 19-pin GPIO port; two general-purpose timers; a wake-up timer; and a system watchdog timer. A 16-bit PWM controller with six output channels is also provided.

The ADuCM360/ADuCM361 are specifically designed to operate in battery-powered applications where low power operation is critical. The microcontroller core can be configured in a normal operating mode that consumes 290 μA/MHz (including flash/ SRAM IDD). An overall system current consumption of 1 mA can be achieved with both ADCs on (input buffers off), PGA gain of 4, one SPI port on, and all timers on.

The ADuCM360/ADuCM361 can be configured in a number of low power operating modes under direct program control, including a hibernate mode (internal wake-up timer active) that consumes only 4 μA. In hibernate mode, peripherals such as external interrupts or the internal wake-up timer can wake up the device. This mode allows the part to operate with ultralow power and still respond to asynchronous external or periodic events.

CoolSiC™ generation 5 represents Infineon’s leading edge technology for SiC Schottky Barrier diodes. The Infineon proprietary diffusion soldering process, already introduced with G3, is now combined with a new, more compact design and thin wafer technology. The result is a new family of products showing improved efficiency over all load conditions, coming from both the improved thermal characteristics and a lower figure of merit (Q c x V f).

The TLE4254GS is a monolithic integrated low-dropout voltage tracking regulator with high accuracy in small PG- DSO-8 packages. The IC is designed to supply off-board systems, e.g. sensors in powertrain management systems under the severe conditions of automotive applications. Therefore, the IC is equipped with additional protection functions against reverese polarity and short circuit to GND and battery. With supply voltages up to 40 V, the output voltage follows a reference voltage applied at the adjust input with very high accuracy. The reference voltage applied directly to the adjust input or by an e.g. external resistor divider can be 2.0 V at minimum. The output is able to drive loads up to 70 mA while the device follows with high accuracy the e.g. 5 V output of a main voltage regulator acting as a reference.

The TLE7250GVIO is a transceiver designed for CAN networks in automotive and industrial applications. As an interface between the physical bus layer and the CAN protocol controller, the TLE7250GVIO drives the signals to the bus and protects the microcontroller against interferences generated within the network. Based on the high symmetry of the CANH and CANL signals, the TLE7250GVIO provides a very low level of electromagnetic emission (EME) within a wide frequency range. The TLE7250GVIO is integrated in a RoHS-compliant PG-DSO-8 package and fulfills or exceeds the requirements of ISO11898-2. As a successor to the first generation of HS CAN transceivers, the pin assignment and function of the TLE7250GVIO is fully compatible with its predecessor model, the TLE6250GV33. The TLE7250GVIO is optimized to provide an excellent passive behavior in the power-down state. This feature makes the TLE7250GVIO extremely suitable for mixed supply CAN networks. Based on the Infineon Smart Power Technology SPT, the TLE7250GVIO provides excellent ESD immunity together with a very high electromagnetic immunity (EMI). The Infineon Smart Power Technology SPT allows bipolar and CMOS control circuitry in accordance with DMOS power devices to exist on the same monolithic circuit. The TLE7250GVIO and the Infineon SPT technology are AEC qualified and tailored to withstand the harsh conditions of the Automotive Environment. Two different operating modes, additional fail-safe features like TxD time-out and the optimized output slew rates on the CANH and CANL signals make the TLE7250GVIO the ideal choice for large CAN networks with high data transmission rates.
