For engineers reviewing the EV-ADUCM350-4WBCZ datasheet, EV-ADUCM350-4WBCZ pinout, EV-ADUCM350-4WBCZ application, or EV-ADUCM350-4WBCZ equivalent, this page delivers verified hardware interface details, supported sensor excitation topologies, USB 2.0 host connectivity, LCD segment control capability, and low-power AFE sequencing - all critical for rapid prototyping of portable electrochemical measurement systems.

Technical Context

The EV-ADUCM350-4WBCZ provides full access to the ADuCM350's analog front-end (AFE), including its reconfigurable ultralow-leakage switch matrix (RON ≤ 50 Ω, DC off-leakage ≤ 370 pA), transimpedance amplifier (±5 mA range), and DFT-based impedance engine with ±0.17° phase accuracy. It routes all 120 BGA signals to test points and headers for direct probing and external sensor interfacing.

It supports dual power domains (2.5–3.6 V main, 1.62–3.6 V backup), integrated USB 2.0 PHY with 3.2–3.4 V regulated output, and programmable LCD charge pump (VLCDVDD adjustable in 40 mV steps). The board implements the ADuCM350's autonomous AFE sequencer and real-time clock with battery-backed operation.
