STMicroelectronics STEVAL-ICB001V1

Overview

STEVAL-ICB001V1 from STMicroelectronics is a capacitive touch sensor demonstration board built around the STMPE1208S capacitive touch controller and ST72F63B I²C master microcontroller, supporting standalone operation with 64×128 monochrome LCD feedback and PC GUI mode via Mini-B USB, powered by USB or AAA Ni batteries.

For engineers reviewing the STEVAL-ICB001V1 datasheet, STEVAL-ICB001V1 pinout, STEVAL-ICB001V1 application, or STEVAL-ICB001V1 equivalent, this board serves as a validated hardware platform for evaluating STMPE1208S-based touch key/slider/rotator interfaces, I²C host firmware integration, and embedded capacitive sensing system architecture.

Technical Context

The board implements a two-chip architecture: ST72F63B acts as dedicated I²C master controlling the STMPE1208S slave device, which handles raw capacitive sensing across up to 12 keys, 1 slider, and 1 rotator channel. All touch data is processed internally by STMPE1208S and transmitted over I²C in register-mapped format.

Power management includes dual-source selection (USB 5 V or battery), on-board voltage regulation for core logic (3.3 V), and configurable reset and clock circuitry for both controllers. The ICC header enables in-circuit reprogramming of the ST72F63B Flash memory without removing the MCU.

FAQ

Is STEVAL-ICB001V1 still in production?

No - STEVAL-ICB001V1 is marked Obsolete by STMicroelectronics as of its November 2008 datasheet revision. It remains available through authorized legacy distributors and Aetrix Electronics' extended-life inventory program for design continuity and legacy system maintenance.

What software tools are included with the board?

The board ships with Windows-based host GUI software, complete ST72F63B firmware source code (in C), and documentation enabling full customization of touch behavior, display output, and I²C communication protocol - no additional license or subscription required.

Can the STMPE1208S be replaced with a newer ST touch controller?

Direct replacement is not supported: STMPE1208S has unique register mapping and interrupt handling. However, ST's later STMPE811 or STMPE1600 offer compatible functionality with updated drivers; migration requires firmware and PCB layout changes per respective datasheets.

Does the board support external microcontrollers besides ST7?

Yes - the I²C bus is accessible via test points and headers, allowing connection to external hosts (e.g., STM32, Arduino, or custom MCU). The ST7 firmware can be bypassed entirely by disconnecting its SCL/SDA lines and using the STMPE1208S directly as a slave device.
