Product details
Overview
STEVAL-IFS003V1 from STMicroelectronics is an evaluation board featuring the ST72F651AR6 microcontroller, dual I²C temperature sensors (STDS75 and STLM75), NAND flash memory, and real-time clock (M41T81S), enabling USB-powered temperature monitoring, data logging, and fan speed regulation in embedded thermal management systems.
For engineers reviewing the STEVAL-IFS003V1 datasheet, STEVAL-IFS003V1 pinout, STEVAL-IFS003V1 application, or STEVAL-IFS003V1 equivalent, this board supports dual-sensor thermal profiling, mass-storage-mode firmware updates, GUI-driven mode switching between sensor and storage functions, and standalone operation with battery-backed RTC and alarm-triggered buzzer/LED outputs.
Technical Context
The board implements a dual-mode architecture: default USB mass-storage mode leverages the ST72F651's built-in USB interface and NAND flash for drag-and-drop firmware/data transfer; temperature sensor mode uses the same MCU to sample STDS75/STLM75 via I²C, log data to NAND, regulate PWM fan output, and drive LCD/LED/buzzer alerts.
Real-time clock (M41T81S) provides battery-backed time-stamping for logged entries; on-board L7805 linear regulator supplies stable 5 V to peripherals; ST72F651AR6 operates at 12 MHz (main oscillator) and 32.768 kHz (RTC crystal), supporting both high-speed and low-power execution contexts.

FAQ
What operating modes does the STEVAL-IFS003V1 support, and how are they selected?
The board operates in two mutually exclusive modes: default USB mass-storage mode (appears as removable drive) and temperature sensor mode (data acquisition and fan control). Mode switching is performed exclusively via the provided Windows GUI application-no hardware jumpers or DIP switches are used. The GUI communicates over USB CDC to reconfigure the ST72F651's firmware runtime behavior.
Does the board support battery-backed data logging when disconnected from USB?
Yes-the M41T81S real-time clock includes a dedicated Vbat pin (J1 pin 3) for external coin-cell backup, preserving time/date during USB disconnection. However, full data logging requires continuous power: NAND flash writes and MCU operation cease without USB or external DC supply; only RTC continues running on battery.
Can the STDS75 and STLM75 sensors be used simultaneously, and what is their I²C addressing scheme?
Yes-both sensors share the same I²C bus (SDA/SCL pins on U4 and TS1/TS2) and operate concurrently. STDS75 uses address 0x48 (A2–A0 = 000); STLM75 uses 0x49 (A2–A0 = 001), configured by onboard resistor networks (R12/R13 for STLM75; R9/R10 for STDS75), enabling independent readout without bus contention.
Is the LCD display driven directly by the ST72F651, and what interface does it use?
Yes-the TS12232C 122×32 monochrome LCD is controlled directly by the ST72F651 via 8-bit parallel interface (DB0–DB7 on PA0–PA7), with E1/E2 enable signals and R/W line managed by PD4 and PC0–PC3. No external controller or framebuffer IC is used; all display rendering is handled in firmware using the MCU's GPIO and timing resources.
