NAFE93352-EVB Overview
An analog front-end (AFE) is the circuit stage between real-world sensors and actuators and a digital controller, conditioning, converting, and digitizing analog signals before processing. In the power-management hierarchy of an industrial system, the AFE sits between signal conditioning (amplifiers, filters) and the MCU or PLC backplane, translating raw voltage and current measurements into digital data for control loops.
The underlying NAFE93352 is a software-configurable universal I/O AFE whose channels can be programmed as voltage or current inputs and outputs, covering the diverse I/O module requirements of modern process control. NXP positions the NAFE93352 as the high-speed member of the family, while the NAFE33352 serves as the low-power version for battery-backed and density-optimized modules. Both target programmable logic controllers (PLC), process control systems, industrial I/O modules, and data loggers.
The NAFE93352-EVB lets engineers exercise these configurable channels, evaluate accuracy against industrial measurement requirements, and prototype analog I/O card designs before committing to custom PCB layouts. Software tooling from NXP supports configuration of channel modes and evaluation of measurement performance.
Typical evaluation scenarios include 4-20 mA current-loop input/output emulation for process instrumentation, multi-channel voltage acquisition cards for PLCs, and data-logger front ends that must combine measurement accuracy with flexible channel configuration.
When evaluating, budget for stable reference and supply rails on the bench, since AFE accuracy measurements are only as good as the external references and wiring quality used during testing.

Typical Applications
NAFE93352-EVB is suitable for 6 applications: PLC Analog I/O Modules, Process Control Instrumentation, Industrial Data Loggers, Distributed I/O and Remote Terminal Units, Test and Measurement Equipment, Building and Factory Automation Sensors.
PLC Analog I/O Modules
The NAFE93352-EVB is the fastest way to validate an NAFE93352-based analog I/O card design for programmable logic controllers. NXP explicitly lists PLCs among the ideal applications for the AIO-AFE family, whose channels are software-configurable as voltage or current inputs and outputs - exactly the mixed channel mix a PLC analog card must serve. During evaluation, engineers can reconfigure channels in software rather than re-spinning hardware, dramatically shortening the design cycle for multi-channel I/O modules. The high-speed classification of the NAFE93352 supports multiplexed acquisition across many channels, a key requirement for dense I/O cards. Prototype channel settling, accuracy, and current-drive behavior on the EVB before committing to a production PCB layout with isolation and field-wiring provisions.

Process Control Instrumentation
Process control loops depend on accurate, stable measurement of process variables and reliable output of actuator commands. The NAFE93352 is described by NXP as meeting high-precision and high-accuracy measurement and control requirements of industrial-grade applications, making it a strong fit for transmitter interfaces, control-room I/O, and closed-loop process instrumentation. With the NAFE93352-EVB, a controls engineer can benchmark the AFE's voltage and current measurement accuracy against the loop error budget before finalizing hardware. The software-configurable AIO architecture lets one silicon device serve multiple channel types (e.g., voltage inputs on some channels, current outputs on others), simplifying BOM and calibration strategy. The high-speed variant also suits fast control loops where sample latency affects loop stability margins.
Recommended
Industrial Data Loggers
Data loggers must capture many heterogeneous signals - thermocouple-conditioned millivolt levels, 4-20 mA current loops, and raw voltage rails - on a single acquisition platform. The NAFE93352's universal software-configurable input/output channels directly address this heterogeneity, letting the logger firmware assign channel modes at commissioning time. NXP lists data loggers among the target applications of the AIO-AFE family. Using the NAFE93352-EVB, a designer can verify accuracy, channel crosstalk, and throughput for the high-speed NAFE93352 variant, then choose the low-power NAFE33352 if battery runtime dominates. Because configuration is software-defined, one logger PCB design can serve multiple product variants, reducing hardware NRE while the EVB validates both the electrical and the configuration-software layers early.
Recommended
Distributed I/O and Remote Terminal Units
Remote I/O nodes and RTUs scattered across a plant floor or field installation need compact, accurate analog front-ends that can mix input and output channels in one device. The NAFE93352's software-configurable AIO channel architecture means one front-end IC covers both field measurement (voltage/current inputs) and field actuation (current/voltage outputs), reducing component count per node. The NAFE93352-EVB allows the designer to exercise exactly the channel mix planned for the remote node and measure real-world accuracy before committing to a custom, possibly conformally-coated, production board. The high-speed class of the NAFE93352 supports scanning many remote channels within short cycle times, which matters for plant-wide monitoring and control loops closed over fieldbus networks.
Recommended
Test and Measurement Equipment
Bench instruments, modular measurement cards, and automated test equipment benefit from a front-end whose channels can be repurposed in firmware as system requirements evolve. The NAFE93352 is NXP's high-speed software-configurable AIO-AFE, combining precision measurement with input and output capability - a natural fit for multi-function acquisition hardware. The NAFE93352-EVB enables an instrument designer to characterize the AFE's accuracy, linearity behavior, and channel switching dynamics under realistic signal conditions before designing the instrument's analog board. Because channel functions are software-configurable, a single validated hardware platform can later be sold as multiple instrument variants with different channel mixes, maximizing the return on the initial evaluation effort performed on this EVB.
Recommended
Building and Factory Automation Sensors
Automation nodes that bridge field sensors and actuators - motor-current monitors, environmental transmitters, actuator controllers - need precise analog acquisition and drive in one package. The NAFE93352's software-configurable universal channels support exactly this mixed-signal role, and its industrial-grade precision targets meet the measurement classes typical of building and factory automation. The NAFE93352-EVB lets the designer validate the front-end against the specific sensor types in the node - checking voltage ranges, current-loop drive, and settling on the bench. For power-sensitive or battery-backed nodes, NXP's low-power NAFE33352 variant (evaluated on the NAFE33352-EVB) provides a drop-in family alternative with the same software architecture, so firmware investment transfers between the high-speed and low-power variants.

Key Differentiators
- High-speed class within a configurable AIO family (vs NAFE33352-EVB)

- Trade-off: no cross-brand drop-in alternative (vs NAFE33352-EVB)
Design Notes
Do not extrapolate accuracy results from the NAFE93352-EVB to the NAFE33352 without re-measurement: NXP designates the NAFE93352 as the high-speed version and the NAFE33352 as the low-power version of the family, and speed and power characteristics differ between them. If your production roadmap includes both variants, evaluate both boards early so the firmware abstraction layer is validated against each device's real behavior rather than assumed equivalence.
Evaluation-board accuracy measurements are only as good as the bench setup. Use low-noise linear supplies or well-filtered bench supplies for the analog rails during evaluation, keep leads short, and use shielded or twisted-pair cabling for current-loop signals. Ground loops between the host PC, the bench supply, and the EVB are a common source of misleading error readings when characterizing a precision AFE like the NAFE93352.
When translating the EVB evaluation into a production I/O module, preserve the reference and analog-ground routing practices demonstrated on the evaluation board, and budget for field-side protection (TVS, current limiting) that the EVB may not fully populate. Because NAFE93352 channels are software-configurable as voltage or current inputs and outputs, plan the production PCB so every channel supports both modes electrically, even if firmware assigns modes at commissioning time.
