Analog Devices Inc. EV-ADUCM350-SMCZ

Overview

EV-ADUCM350-SMCZ from Analog Devices is a fully integrated evaluation platform for the ADuCM350 precision analog microcontroller, designed for electrochemical and bioimpedance measurement systems. It features a 16-bit, 160 kSPS ADC; 8 current and 4 voltage measurement channels; autonomous impedance measurement engine (DFT-based); 16 MHz ARM Cortex-M3 core; 384 kB flash; and USB 2.0 interface - enabling rapid prototyping of point-of-care diagnostics and wearable vital-sign monitors.

For engineers reviewing the EV-ADUCM350-SMCZ datasheet, EV-ADUCM350-SMCZ pinout, EV-ADUCM350-SMCZ application, or EV-ADUCM350-SMCZ equivalent, this board delivers validated hardware reference design, preloaded firmware for sensor excitation/measurement sequencing, full schematic documentation, and direct USB connectivity for real-time data capture and algorithm development in portable medical instrumentation.

Technical Context

The EV-ADUCM350-SMCZ implements the complete ADuCM350 AFE architecture - including reconfigurable ultralow-leakage switch matrix (RON ≤ 50 Ω, DC off-leakage ≤ 370 pA), transimpedance amplifier (±5 mA range), 12-bit DAC (±600 mV output), and precision 1.8 V reference (±0.17% initial accuracy, ±90 ppm/°C TC). Its signal chain supports amperometric, voltametric, and impedometric biosensing with DFT-based complex impedance calculation at up to 20 kHz.

It integrates all required power management for coin-cell operation: dual LDOs (AFE/Digital @ 1.8 V), trickle charger (0.48 mA), VBACK backup support, and dynamic clock/power gating. The board exposes all 120-ball CSP_BGA signals via 0.5 mm pitch test points and includes LCD segment driver, CapTouch controller, and programmable GPIOs for system-level integration.

FAQ

What is the primary function of the EV-ADUCM350-SMCZ evaluation board?

The EV-ADUCM350-SMCZ is a fully assembled and tested evaluation platform for the ADuCM350 meter-on-chip microcontroller. It enables engineers to validate electrochemical and bioimpedance measurement performance, run preloaded firmware for sensor excitation and DFT-based analysis, and develop application code using the CrossCore Embedded Studio IDE. The board provides direct access to all ADuCM350 interfaces - including USB, LCD, CapTouch, and sensor analog front-end connections - without requiring custom PCB design.

Does the EV-ADUCM350-SMCZ support coin-cell battery operation out of the box?

Yes, the EV-ADUCM350-SMCZ is configured for immediate CR2032 coin-cell operation (2.5 V–3.6 V) with onboard power management, including AFE and digital LDOs, trickle charger (0.48 mA), and VBACK supercapacitor backup path. It maintains full functionality across the −40°C to +85°C temperature range and supports dynamic power gating to extend battery life in portable diagnostic applications using the EV-ADUCM350-SMCZ.

Can the EV-ADUCM350-SMCZ perform complex impedance measurements without external components?

Yes - the EV-ADUCM350-SMCZ leverages the integrated DFT-based impedance measurement engine within the ADuCM350 to compute magnitude and phase of complex impedance (e.g., 0.33% magnitude accuracy, 0.17° phase accuracy at 20 kHz) using only on-chip resources. No external FFT processor or signal generator is required; excitation waveforms are generated by the internal DDS, and measurements are processed autonomously by the AFE sequencer and DFT accelerator on the EV-ADUCM350-SMCZ.

What software tools and firmware are included with the EV-ADUCM350-SMCZ?

The EV-ADUCM350-SMCZ ships with Analog Devices' ADuCM350 SDK, including device drivers, AFE configuration utilities, USB CDC communication stack, and example projects for amperometry, voltammetry, and impedance spectroscopy. Firmware is preloaded to support immediate sensor connection and real-time data streaming via USB to PC-based visualization tools. All source code, schematics, and layout files are provided under the EV-ADUCM350-SMCZ product documentation package.

Is the EV-ADUCM350-SMCZ compatible with standard JTAG/SWD debuggers?

Yes - the EV-ADUCM350-SMCZ includes a 10-pin SWD/JTAG connector compliant with ARM CoreSight standards, supporting full debug visibility into the ADuCM350's Cortex-M3 core, memory, and peripherals using industry-standard tools such as Segger J-Link, CMSIS-DAP, or Analog Devices' ICE-1000/2000 emulators. Breakout test points for all critical AFE signals allow oscilloscope probing and timing validation during EV-ADUCM350-SMCZ development.
