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.APPLICATIONSOptical networking 100 Gbps/200 Gbps/400 Gbps and higher frequency modulesIndustrial control, automation, and instrumentation systems

The ADuM1100 is a digital isolator based on Analog Devices Inc.,iCoupler®technology. Combining high speed CMOS and monolithic air core transformer technology, this isolation component provides outstanding performance characteristics superior to alternatives, such as optocoupler devices.Configured as a pin-compatible replacement for existing high speed optocouplers, the ADuM1100 supports data rates as high as 25 Mbps and 100 Mbps.The ADuM1100 operates with a voltage supply ranging from 3.0 V to 5.5 V, boasts a propagation delay of <18 ns and edge asymmetry of <2 ns, and is compatible with temperatures up to 125°C. It operates at very low power, less than 0.9 mA of quiescent current (sum of both sides), and a dynamic current of less than 160 μA per Mbps of data rate. Unlike other optocoupler alternatives, the ADuM1100 provides dc correctness with a patented refresh feature that continuously updates the output signal.The ADuM1100 is offered in three grades. The ADuM1100AR and ADuM1100BR can operate up to a maximum temperature of 105°C and support data rates up to 25 Mbps and 100 Mbps, respectively. The ADuM1100UR can operate up to a maximum temperature of 125°C and supports data rates up to 100 Mbps.APPLICATIONSDigital field bus isolationOpto-isolator replacementComputer-peripheral interfaceMicroprocessor system interfaceGeneral instrumentation and data acquisition applications

The ADuM1201 is a dual-channel, digital isolator with 1/1 channel directionality based on the Analog Devices, Inc.,iCoupler®technology. Combining high speed CMOS and monolithic transformer technologies, these isolation components provide outstanding performance characteristics superior to alternatives, such as optocouplers.By avoiding the use of LEDs and photodiodes,iCoupler devices remove the design difficulties commonly associated with optocouplers. The typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with the simpleiCoupler digital interfaces and stable performance characteristics. The need for external drivers and other discrete components is eliminated with theseiCoupler products. Further-more,iCoupler devices consume one-tenth to one-sixth the power of optocouplers at comparable signal data rates.The ADuM120x product family of isolators provides two independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). Both parts operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. In addition, the ADuM120x provide low pulse width distortion (<3 ns for CR grade) and tight channel-to-channel matching (<3 ns for CR grade). Unlike other optocoupler alternatives, the ADuM120x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down conditions.ADuM1200W and ADuM1201W are automotive grade versions qualified for 125°C operation per AEC-Q100.
