STMicroelectronics STEVAL-CCM006V2

Overview

STEVAL-CCM006V2 from STMicroelectronics is an STM32F103ZET6-based evaluation board for NAND Flash driver firmware, supporting 512-byte and 2-kilobyte page SLC NAND Flash via FSMC interface, with automatic Device ID detection, FAT (ELM_FS) file system support, and USB mass storage device mode.

For engineers reviewing the STEVAL-CCM006V2 datasheet, STEVAL-CCM006V2 pinout, STEVAL-CCM006V2 application, or STEVAL-CCM006V2 equivalent, this board enables rapid validation of NAND Flash interfacing, embedded file system integration, USB host/device dual-role implementation, and flash management algorithms including garbage collection, wear leveling, and ECC checking.

Technical Context

The board implements a full NAND Flash controller stack on the STM32F103ZET6 MCU, using its Flexible Static Memory Controller (FSMC) to manage asynchronous NAND timing, address/data multiplexing, and control signals (CLE/ALE/RE/WE/RB/WP). Firmware handles dynamic NAND identification by reading Device ID bytes and adapting timing parameters accordingly.

It supports dual USB modes: Full-Speed (via PA11/PA12) and High-Speed (via ULPI interface with PB0–PB13, PC0–PC3), enabling both mass storage class operation and host-side NAND access. The integrated touch screen controller (TSC) interface uses PG14 for interrupt signaling and PB6/PB7 for I²C communication with the MB785/P TFT module.

FAQ

Is STEVAL-CCM006V2 still in active production?

No - STEVAL-CCM006V2 is marked as Obsolete in ST's official documentation (DocID025468 Rev 1, November 2013). It remains available through authorized distributors for legacy design support and spare-part replacement, but no new silicon revisions or firmware updates are planned.

Can the board interface with modern NAND Flash parts beyond SLC types?

The firmware and hardware are validated only for SLC NAND Flash with 512-byte or 2-kilobyte page sizes and standard ONFI 1.0-compatible command sets. MLC, TLC, or newer ONFI 2.x/3.x parts are not supported due to missing features like multi-plane operations, advanced ECC requirements, and timing constraints.

What USB speed modes does the board support out-of-the-box?

The board supports USB Full-Speed (12 Mbps) device mode using PA11/PA12 and USB High-Speed (480 Mbps) host mode via the ULPI physical layer (PB0–PB13, PC0–PC3). Both modes require separate firmware configurations and cannot operate simultaneously.

Does the board include source code for the NAND driver and file system?

Yes - ST provides complete, commented firmware source code (C and assembly) for the NAND driver stack, FatFs integration, USB mass storage class, and touch screen controller interface, all under a license permitting modification and reuse in commercial products.
