STMicroelectronics STEVAL-PCC005V1

Overview

STEVAL-PCC005V1 from STMicroelectronics is a USB-based hard disk drive (HDD) bridge demonstration board built around the STR912FAW44 ARM966E-S microcontroller, featuring integrated external memory interface (EMI), native USB mass-storage class compliance, on-board HDD power supply, JTAG debug interface, and ESD-protected USB connectivity. It enables rapid evaluation of STR9-based HDD bridging in PC-connected storage applications.

For engineers reviewing the STEVAL-PCC005V1 datasheet, STEVAL-PCC005V1 pinout, STEVAL-PCC005V1 application, or STEVAL-PCC005V1 equivalent, key selection considerations include USB mass-storage protocol implementation, STR9 microcontroller firmware upgrade capability via JTAG, on-board HDD power delivery (5 V/1.5 A), EMI-driven parallel ATA interface support, and LED-indicated read/write/system health status.

Technical Context

The board implements a full USB-to-parallel-ATA bridge using the STR912FAW44's embedded ARM966E-S core and dedicated external memory interface (EMI) to directly manage HDD command/data transfers. USB communication conforms to the USB Mass Storage Class (MSC) specification, enabling plug-and-play operation with native Windows drivers without custom host software.

Hardware-level integration includes a dedicated 5 V/1.5 A on-board SMPS for HDD power, configurable external power input option, discrete ESD protection on USB lines, and real-time status feedback via three LEDs (power, read/write activity, system health). The JTAG interface supports full firmware development, debugging, and field updates of the STR9 application code.

FAQ

Does STEVAL-PCC005V1 support SATA hard drives?

No. The board is designed exclusively for Parallel ATA (PATA/IDE) hard disk drives using the STR912's external memory interface. It lacks SATA PHY, link layer logic, or associated power sequencing for SATA drives. Only 40-pin or 44-pin IDE HDDs with 5 V operation are compatible.

Can the STR9 firmware be reprogrammed without JTAG?

No. Firmware updates require the on-board 20-pin ARM JTAG interface. There is no bootloader accessible via USB or UART; the STR912FAW44 on this board does not expose ROM-based DFU or serial ISP functionality in this configuration.

Is Windows driver installation required for USB mass-storage operation?

No. The board enumerates as a standard USB mass-storage device using Microsoft's built-in usbstor.sys and disk.sys drivers. No additional INF files or vendor-specific drivers are needed on Windows XP SP2 or later, including Windows 10 and 11.

What is the maximum supported HDD capacity?

The board supports HDDs up to 137 GB when used with legacy CHS addressing mode, and up to 2.2 TB with LBA-48 enabled in the STR9 firmware. Actual capacity depends on firmware implementation - the reference design provided by ST supports up to 500 GB reliably.
