STMicroelectronics STEVAL-PCC002V1

Overview

STEVAL-PCC002V1 from STMicroelectronics is an obsolete evaluation board implementing a low-speed USB-to-RS232 serial bridge using the ST72F63B QFN40 microcontroller, supporting HID-class USB protocol, 800 bytes/sec guaranteed transfer rate, CTS/RTS hardware flow control, and in-circuit programming via ICC connector for embedded serial interface prototyping.

For engineers reviewing the STEVAL-PCC002V1 datasheet, STEVAL-PCC002V1 pinout, STEVAL-PCC002V1 application, or STEVAL-PCC002V1 equivalent, this board enables rapid validation of USB-HID bridging firmware, RS232 signal level translation, MCU I/O expansion testing, and in-system firmware updates for legacy serial device integration.

Technical Context

The board implements a full USB-HID class device stack on the ST72F63B, with dedicated firmware handling descriptor enumeration, report-based data exchange, and bidirectional COM port mapping. USB physical layer compliance is achieved via internal transceiver with D+/D− termination and VBUS sensing.

RS232 interface uses ST3222E line driver/receiver for ±15 kV ESD protection, true RS232 voltage levels (±5–±15 V), and independent TxD/RxD/CTS/RTS signal routing. MCU I/Os are exposed on dual 16-pin headers (P1/P2) and ICC connector (J2), enabling custom peripheral attachment and firmware reconfiguration.

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, designing and manufacturing microcontrollers, analog ICs, power devices, and sensors for industrial, automotive, and consumer applications.

This board belongs to ST's STEVAL (ST Evaluation) series, developed specifically to accelerate evaluation of ST microcontroller-based interface solutions, particularly USB-to-legacy-serial bridging and in-system firmware development workflows.

FAQ

Is STEVAL-PCC002V1 still in production?

No. STMicroelectronics has marked STEVAL-PCC002V1 as obsolete per its October 2007 data brief. It is no longer manufactured, but Aetrix Electronics maintains limited legacy stock for design continuity and repair use cases where functional equivalence is acceptable.

What software is required to operate the board?

The board requires ST-provided Windows executable software for HID communication, which handles USB enumeration, COM port mapping, and real-time traffic monitoring. No driver installation is needed-Windows natively supports HID-class devices, and the applet manages report descriptors and data forwarding.

Can the RS232 section be isolated from the USB bridge?

Yes. The RS232 circuit can be physically decoupled by removing solder shunts between the ST3222E and MCU side, allowing independent evaluation of the transceiver or substitution with alternate level-shifting components while retaining USB-HID firmware functionality.

Which microcontroller pins are exposed for custom I/O use?

All 40 pins of the ST72F63B are accessible: PA0–PA7, PB0–PB7, PC0–PC2, and PD0–PD7 appear on P1 and P2 16-pin headers. Additionally, ICC programming signals (VPP, RESET, OSCIN, OSCOUT, PA1/ICCDATA, PA2/ICCCLK) are available on J2 for debugging and firmware loading.
