LCD Interface (LCDIF)
33.1 LCD Interface (LCDIF) Overview
Many products based on the i.MX28 include an LCD panel with an integrated
controller/driver. These smart LCDs are available in a range of sizes and capabilities, from
simple text-only displays to QVGA, 16/18/24 bpp color TFT panels. Traditionally, many
of these display controllers have had an asynchronous parallel MPU interface for command
and data transfer to the frame buffer. There are other popular displays that support moving
pictures and require the RGB interface mode (called DOTCLK interface in this document)
or the VSYNC mode for high-speed data transfers. In addition to these displays, it is also
common to provide support for digital video encoders that accept ITU-R BT.656 format
4:2:2 YCbCr digital component video and convert it to analog TV signals. The LCDIF
block supports all of these different interfaces by providing fully programmable functionality
and sharing register space, FIFOs, and ALU resources at the same time.
The high-level block diagram of the LCD interface is shown in
The block has several major features:
Freescale Semiconductor, Inc.
• High display resolutions up to 800x480 supported.
• AXI-based bus master mode for LCD writes and DMA operating modes for LCD reads
• 8/16/18/24 bit LCD data bus support available depending on the package size.
• Programmable timing and parameters for system, MPU, VSYNC and DOTCLK LCD
• ITU-R BT.656 mode (called Digital Video Interface or DVI mode here) including
requiring minimal CPU overhead.
