STMicroelectronics STEVAL-IFS006V1

Overview

STEVAL-IFS006V1 from STMicroelectronics is a demonstration board for smart inductive proximity switching, implementing eddy-current-based metal detection using a 68 µH HF oscillator coil, ST7LITEUS5 8-bit microcontroller, and TDE1708DFT intelligent power switch. It supports PNP/NPN output configurations, analog/digital temperature compensation, and operates from 6 V to 48 V DC across –25 °C to +85 °C.

For engineers reviewing the STEVAL-IFS006V1 datasheet, STEVAL-IFS006V1 pinout, STEVAL-IFS006V1 application, or STEVAL-IFS006V1 equivalent, this board serves as a validated reference design for industrial proximity sensing with in-circuit programming, overload protection, and configurable hysteresis-enabling rapid evaluation of sensor firmware, output drive behavior, and coil interface tuning.

Technical Context

The board implements a single-transistor HF oscillator whose frequency shift under metallic target presence is digitized by the ST7LITEUS5's on-chip ADC (PA0–PA5 analog inputs). The MCU executes real-time thresholding, hysteresis control, and temperature compensation algorithms before driving the TDE1708DFT's high-side/low-side outputs via ICCDATA/ICCCLK serial interface.

TDE1708DFT provides protected switching with integrated GND/VS open-wire detection, short-circuit current limiting (typ. 1.2 A), and thermal shutdown. Its H.S. OUT and L.S. OUT pins support configurable PNP or NPN sourcing/sinking modes, while status LED (D1) and diagnostic LED (D3) provide visual feedback aligned with output state and fault conditions.

FAQ

Is STEVAL-IFS006V1 still in active production?

No-STMicroelectronics has marked STEVAL-IFS006V1 as obsolete per its July 2008 data brief revision history. It remains available through authorized distributors for legacy design support and spare-part replacement, but no new silicon revisions or firmware updates are planned.

Can the ST7LITEUS5 firmware be reprogrammed without ST proprietary tools?

Yes-the board supports in-circuit programming via the ICC interface (P2 header) using standard ST-LINK/V2 or compatible debuggers. The STVP (ST Visual Programmer) or STM8 eForth toolchain can load custom .s19 or .hex files directly to the ST7LITEUS5's internal Flash memory.

What coil parameters are required for replacement or customization?

The reference design uses a 68 µH, ±10 % tolerance, shielded inductor (e.g., Würth Elektronik 744040680) with self-resonant frequency >5 MHz. Coil Q-factor ≥30 at 500 kHz and DC resistance <1 Ω are critical to maintain oscillator stability and detection repeatability.

Does the board support IO-Link or other digital fieldbus interfaces?

No-STEVAL-IFS006V1 implements only discrete PNP/NPN switching outputs. It lacks physical layer transceivers, protocol stacks, or configurable digital communication peripherals required for IO-Link, AS-i, or DeviceNet. Integration into such networks requires external gateway hardware.
