The ADuCM410 is a fully integrated, single package device that includes high performance analog peripherals together with digital peripherals (controlled by a 160 MHz Arm? Cortex?-M33 processor) and integrated flash for code and data.The analog-to-digital converter (ADC) on the ADuCM410 provides 16-bit, 2 MSPS data acquisition using up to 16 input pins that can be programmed for single-ended or differential operation with a programmable gain amplifier (PGA) or transimpedance amplifier (TIA) for voltage and current measurements. Additionally, the die temperature and supply voltages can be measured.The ADC input voltage is 0 V to VREF. A sequencer is provided that allows a user to select a set of ADC channels to be measured in sequence without software involvement during the sequence. The sequence can optionally repeat automatically at a user-selectable rate.Up to 12 channels of 12-bit voltage digital-to-analog converters (VDACs) are provided with output buffers supported.The ADuCM410 can be configured so that the digital and analog outputs retain their output voltages through a watchdog or software reset sequence. Therefore, a product can remain functional even while the ADuCM410 is resetting itself.The ADuCM410 has a low power Arm Cortex-M33 processor and a 32-bit reduced instruction set computer (RISC) machine that offers up to 240 MIPS peak performance with a floating-point unit (FPU). Also integrated are 2? 512 kB Flash/EE memories and 128 kB static random access memory (SRAM)?both with single-error correction (SEC) and double error detection (DED) error checking and correction (ECC). The flash comprises two separate 512 kB blocks supporting execution from one flash block and simultaneous writing and/or erasing of the other flash block.The ADuCM410 operates from an on-chip oscillator and has a phase-locked loop (PLL) of 160 MHz. This clock can optionally be divided down to reduce current consumption. Additional low power modes can be set via the ADuCM410 software.The device includes a management data input/output (MDIO) interface capable of operating up to 10 MHz. User programming is eased by incorporating physical address (PHYADR) and device address (DEVAD) hardware comparators. The nonerasable kernel code combined with flags in user flash allow user code to reliably switch between the two hardware independent flash blocks.The ADuCM410 integrates a range of on-chip peripherals that can be configured under software control, as required in the application. These peripherals include 2? universal asynchronous receiver transmitter (UART), 3? I2C, and 3? serial peripheral interface (SPI) serial input/output communication controllers, general-purpose inputs/outputs (GPIOs), 32-element programmable logic arrays (PLAs), five general-purpose timers, a wake-up timer (WUT), and a system watchdog timer (WDT). A 16-bit pulse-width modulation (PWM) with eight output channels is also provided.The GPIO pins (Px.x) power up in high impedance input mode. In output mode, the software chooses between open-drain mode and push/pull mode. The pull-up and pull-down resistors can be disabled and enabled in the software. The GPIO pins can be configured with different voltage levels according to the IOVDDx pin, such as 3.3 V, 1.8 V, and 1.2 V. In GPIO output mode, the inputs can remain enabled to monitor the GPIO pins. The GPIO pins can also be programmed to handle digital or analog peripheral signals, in which case, the pin characteristics are matched to the specific requirement.A large support ecosystem is available for the Arm Cortex-M33 processor to ease product development of the ADuCM410. Access is via the Arm serial wire debug port. On-chip factory firmware supports in-circuit serial download via MDIO or I2C. These features are incorporated into a low cost, quick start development system supporting this precision analog microcontroller.Note that throughout this data sheet, multifunction pins, such as VDAC7/P4.2, are referred to either by the entire pin name or by a single function of the pin, for example, P4.2, when only that function is relevant.APPLICATIONS Optical networking 100 Gbps/200 Gbps/400 Gbps and higher frequency modules Industrial control, automation, and instrumentation systems

The LTC3850 is a high performance dual synchronous step-down switching regulator controller that drives all N-channel power MOSFET stages. A constant-frequency current mode architecture allows a phase-lockable frequency of up to 780kHz. Power loss and supply noise are minimized by operating the two controller output stages out of phase.OPTI-LOOP? compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values.

The LTC3897 is a synchronous boost DC/DC controller with surge stopper and ideal diode controller.The boost controller drives two N-channel power MOSFET stages out-of-phase to reduce input and output capacitor?requirements, allowing the use of smaller inductors than the single-phase equivalent. Synchronous rectification reduces power loss and eases thermal requirements.The surge stopper controls the gate of an external N-channel MOSFET to protect against high voltage input transients and provides in-rush current control, overcurrent protection and output disconnect for the boost converter. The integrated ideal diode controller drives another N-channel MOSFET to replace a Schottky diode for reverse input protection and voltage holdup or peak detection. It controls the forward voltage drop across the MOSFET and minimizes reverse current flow.The LTC3897 is available in thermally-enhanced 38-pin leadless QFN or 38-lead TSSOP packages.Applications Industrial Automotive Military/Avionics
