STMicroelectronics STEVAL-ICB003V1

Overview

STEVAL-ICB003V1 from STMicroelectronics is a demonstration board implementing a smart touchpanel interface for white goods front panels, integrating the STMPE1208S capacitive touch controller, STLED316S LED driver, and STM8S207K6 8-bit microcontroller. It features 8 touchkeys, 4×7-segment LED displays, rotary encoder input, water level sensor interface (38–43 kHz), relay-controlled host power switching, and standby management with wake-up capability.

For engineers reviewing the STEVAL-ICB003V1 datasheet, STEVAL-ICB003V1 pinout, STEVAL-ICB003V1 application, or STEVAL-ICB003V1 equivalent, this board serves as a validated reference design for cost-sensitive, low-power front panel systems in washing machines, DVD recorders, set-top boxes, and similar consumer appliances requiring integrated touch, display, sensing, and power control functions.

Technical Context

The board implements a complete front-panel subsystem using three core ST components: the STMPE1208S provides 8-channel capacitive touch sensing with interrupt-driven GPIO output and I²C interface; the STLED316S drives up to 8 segments × 7 digits plus 8 discrete LEDs with programmable current and serial interface (DIN/DOUT/CLK/STB); the STM8S207K6 executes system logic, manages standby/wake-up sequencing, processes rotary encoder signals, and interfaces with external sensors including a 38–43 kHz water level transducer.

Power architecture includes single 9 V DC input, on-board 5 V regulation (LD1117S50CTR), relay-driven host power control, bi-color LED status indication, buzzer feedback, and SWIM-based in-circuit programming. Standby current is minimized via firmware-controlled peripheral gating and deep-sleep modes across all ICs.

FAQ

What is the primary function of the STEVAL-ICB003V1 board?

The STEVAL-ICB003V1 is a fully assembled demonstration board that implements an integrated front-panel solution for white goods and consumer electronics. It combines capacitive touch sensing, multi-digit LED display driving, rotary encoder handling, water level detection, relay-based power control, and low-power standby management - all coordinated by the onboard STM8S207K6 microcontroller.

Does the board support in-system programming and debugging?

Yes. The board includes a standard 4-pin SWIM connector (J2) enabling full in-circuit programming and debugging of the STM8S207K6 microcontroller using ST's ST-LINK tools. Firmware updates and real-time debugging are supported without removing the MCU from the board.

Can the water level sensor interface be used with non-ST sensors?

Yes. The water level input is a generic AC-coupled analog front-end designed for 38–43 kHz resonant transducers. It accepts any compatible piezoelectric or inductive sensor generating a ~40 kHz signal; no ST-specific protocol or calibration is required - signal amplitude and frequency fall within the board's comparator and filtering design envelope.

Is the relay on the board rated for mains voltage switching?

No. The RL1 relay is a 5 V coil, SPDT, 1 A / 30 VDC-rated device intended for switching low-voltage DC loads only - such as enabling/disabling a host system's 5 V supply rail. It is not certified or rated for direct AC mains (110/230 VAC) connection and must not be used in high-voltage or safety-critical power paths.
