STMicroelectronics STEVAL-PCC012V1

Overview

STEVAL-PCC012V1 from STMicroelectronics is a connectivity gateway demonstration board built around the STM32F107VC ARM Cortex-M3 microcontroller. It integrates Ethernet (RMII/MII), USB OTG, dual Wi-Fi module footprints, microSD card socket (SPI), PRIME power-line networking interface, and analog/digital extension headers compatible with ST's MEMS and audio expansion boards.

For engineers reviewing the STEVAL-PCC012V1 datasheet, STEVAL-PCC012V1 pinout, STEVAL-PCC012V1 application, or STEVAL-PCC012V1 equivalent, key selection considerations include its dual-protocol gateway architecture (Ethernet + USB OTG), industrial DC input range (7–35 V), on-board JTAG debug interface, and interoperability with ST's ecosystem of extension boards for rapid prototyping of smart grid, industrial IoT, and embedded connectivity solutions.

Technical Context

The board implements a full-featured connectivity hub using the STM32F107VC - a 72 MHz Cortex-M3 MCU with integrated Ethernet MAC, USB 2.0 OTG PHY, and multiple serial interfaces (I²C, SPI, USART). Its hardware abstraction enables simultaneous protocol bridging between Ethernet, USB, SD, and PRIME OFDM power-line networks.

Power delivery uses an L7986A DC-DC converter supporting wide-input 7–35 V DC, delivering regulated 3.3 V and 5.3 V rails. The design includes ESD protection (USBLC6-2P6, DVIULC6-2P6), Ethernet magnetics (Pulse J00-0086), and configurable boot options via jumpers JP4/JP5/JP6/JP7 for Wi-Fi module selection and interface mode control.

FAQ

Does STEVAL-PCC012V1 support both MII and RMII Ethernet modes?

Yes. The board supports both MII and RMII through hardware configuration: RMII mode is enabled by default using the MCO signal routed to the PHY's TXCLK, while MII mode can be selected via jumper SB3 and appropriate PHY strap settings (ADD0–ADD4) per the ST802RT1 datasheet. The schematic confirms dual-mode routing capability.

What Wi-Fi modules are supported on the STEVAL-PCC012V1 board?

The board provides two dedicated footprints: one for the ZG2100M/ZG2101M (as shown in Figure 9) and another for an unspecified second module (Figure 10). Both use SPI interface (CS_WIFI, SCK, MISO, MOSI), interrupt (INT_NX), and reset (RESET), with 3.3 V and 1.8 V power domains. No specific alternate module model is named in the documentation.

Can the microSD card socket be used for firmware updates or data logging?

Yes. The microSD socket (CN2) connects directly to the STM32F107VC's SPI2 peripheral (pins PD3–PD6), enabling FAT file system implementation for firmware image storage, configuration persistence, or time-series sensor data logging - confirmed by the schematic and reference to "CS_SDcard" and "SCK/MISO/MOSI" signals.

Is the PRIME power-line networking interface fully implemented on the board?

No. The board includes only the extension connector (CN7) and footprint for the ST7590 "PRIME" narrow-band OFDM board - it does not integrate the ST7590 IC or associated analog front-end. Users must mount the separate STEVAL-PRIME board onto CN7 to enable PRIME-compliant power-line communication.
