STMicroelectronics STEVAL-PCC004V1

Overview

STEVAL-PCC004V1 from STMicroelectronics is a low-speed USB demonstration board built around the STUSB02E USB transceiver and ST72F63BE2 8-bit microcontroller, supporting USB full-speed and low-speed operations with mini-B connector interface, HID GUI software, and jumper-configurable signal routing for rapid prototyping of embedded USB peripheral functions.

For engineers reviewing the STEVAL-PCC004V1 datasheet, STEVAL-PCC004V1 pinout, STEVAL-PCC004V1 application, or STEVAL-PCC004V1 equivalent, this board enables hands-on validation of USB HID device behavior, transceiver-to-microcontroller signal integrity, power sourcing options (USB or external), and hardware-level USB line termination and pull-up configuration in consumer electronics peripherals.

Technical Context

The board implements a complete low-speed USB peripheral interface using the STUSB02E transceiver, which handles physical layer signaling (D+, D−), ESD protection, and automatic speed detection, directly interfaced to the ST72F63BE2's dedicated USB I/O pins without external level-shifting or buffering.

Signal routing includes two 2-to-4 demultiplexers for flexible test point access to USB lines and microcontroller signals, while onboard pull-up resistors, series termination resistors, and decoupling capacitors comply with USB 2.0 specification requirements for host enumeration and signal integrity.

FAQ

Is STEVAL-PCC004V1 still in production?

No - STEVAL-PCC004V1 is marked obsolete by STMicroelectronics as of its 2008 release. It remains available through authorized legacy distributors and Aetrix Electronics' extended-life inventory program for design continuity and repair support.

What USB device class does it demonstrate?

The board implements a Human Interface Device (HID) class peripheral, confirmed by its bundled demonstration GUI software and firmware that enumerates as a standard HID device under Windows and Linux without custom drivers.

Can it operate without external power?

Yes - the board is fully bus-powered via the USB mini-B connector, drawing regulated 5 V from the host port; an optional external supply input is provided only for isolation during signal integrity or power rail analysis.

Which microcontroller pins connect directly to the STUSB02E?

The ST72F63BE2's dedicated USB I/O pins - specifically PD0 (D−) and PD1 (D+) - connect directly to the STUSB02E transceiver's corresponding differential data terminals, with no intervening logic or level translation.
