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 ADuM3070 isolator is a regulated dc-to-dc isolated power supply controller with an internal MOSFET driver. The dc-to-dc controller has an internal isolated PWM feedback from the secondary side based on the iCoupler? chip scale transformer technology and complete loop compensation. This eliminates the need to use an optocoupler for feedback and compensates the loop for stability.The ADuM3070 isolator provides a more stable output voltage and higher efficiency compared to unregulated isolated dc-to-dc power supplies. The fully integrated feedback and loop compensation in a small QSOP package provides a smaller form factor than any discrete solution. The regulated feedback provides a relatively flat efficiency curve over the full output power range. The ADuM3070 enables a dc-to-dc converter with a 3.3 V to 24 V isolated output voltage range from either a 5.0 V or a 3.3 V input voltage, with an output power of up to 2.5 W.APPLICATIONS Power supply startup bias and gate drives Isolated sensor interfaces Process controls

The ADuM3165/ADuM31661 are USB 2.0 port isolators, utilizing Analog Devices, Inc., iCoupler? technology to dynamically support all USB 2.0 data rates: low (1.5 Mbps), full (12 Mbps), or high (480 Mbps), as required. The devices support host isolation with automatic speed negotiation as well as peripheral isolation.High speed data is retimed for jitter reduction, requiring an external clock signal or crystal input. The ADuM3165 supports the clock or crystal input on the upstream side, and the ADuM3166 supports the clock or crystal input on the downstream side, offering two options to best suit the system design.The low power standby mode for downstream (Side 2) supports applications with limited available power, such as battery-operated peripherals. The upstream (Side 1) standby current meets USB 2.0 requirements for suspended operation.The isolators are specified over an extended industrial temperature range of ?55?C to +125?C and are available in a compact 20-lead shrink small outline package (SSOP) with 5.3 mm creepage and clearance.APPLICATIONS USB peripheral, USB host, and USB hub isolation Electronic test and measurement equipment Medical devices and integrated PCs Industrial PCs and isolated USB ports for debug or upgrade USB isolator modules and USB cable isolators1 Protected by U.S. Patents 5,952,849; 6,873,065; 6,903,578; and 7,075,329.
