STMicroelectronics STEVAL-CCM002V1

Overview

STEVAL-CCM002V1 from STMicroelectronics is a TFT-LCD panel demonstration board using the STM32F103VET6 microcontroller as an LCD controller via its Flexible Static Memory Controller (FSMC) interface, driving a 3.5" QVGA TFT-LCD with external SRAM-based refresh buffer and on-board constant-current LED backlight driver with dimming control.

For engineers reviewing the STEVAL-CCM002V1 datasheet, STEVAL-CCM002V1 pinout, STEVAL-CCM002V1 application, or STEVAL-CCM002V1 equivalent, this board serves as a validated reference for STM32 FSMC-driven TFT-LCD interfacing, backlight power management, and static image slideshow implementation without dedicated display controllers.

Technical Context

The board implements the STM32F103VET6's FSMC peripheral in NOR/PSRAM mode to generate parallel RGB timing signals (HSYNC, VSYNC, DE, PCLK) and pixel data bus for direct TFT-LCD drive. External 256 KB SRAM provides frame buffer storage, eliminating need for internal MCU RAM allocation.

Backlight control uses a single-channel inverter circuit with constant-current LED driver and PWM-dimmable current regulation. Jumper-configurable signal taps allow real-time probing of FSMC address/data/control lines between MCU and LCD interface.

FAQ

Is STEVAL-CCM002V1 still in production?

No. STEVAL-CCM002V1 is marked obsolete per STMicroelectronics' official documentation (Doc ID 17541 Rev 1, June 2010). It remains available through authorized legacy distributors and Aetrix Electronics' inventory for design continuity, but no new manufacturing or technical support is provided by ST.

Can this board operate standalone without STM3210E-EVAL?

No. STEVAL-CCM002V1 lacks onboard power regulation, debug interface, and system clock generation; it requires connection to the STM3210E-EVAL base board for 3.3 V supply, SWD debugging, and master clock distribution to the STM32F103VET6.

What display resolutions does the FSMC configuration support?

The board is validated for QVGA (320×240) only. While the STM32F103VET6 FSMC supports higher bandwidth modes, this design uses fixed PCB routing, SRAM size, and timing constraints limiting operation to QVGA resolution with standard 60 Hz refresh.

Does the board include touchscreen functionality?

Yes. Schematic Figure 3 confirms inclusion of a dedicated touchscreen controller IC (unspecified part number in public doc), integrated with the single-channel inverter and backlight driver section, supporting 4-wire resistive touch input routed to STM32 GPIOs.
