Display Control Unit (DCU)
The DCU is a display controller designed to drive TFT LCD displays capable of driving up to WQVGA resolution screens with
16 layers and 4 planes with real time alpha-blending.
The DCU generates all the necessary signals required to drive the display: up to 24-bit RGB data bus, Pixel Clock, Data Enable,
Horizontal-Sync and Vertical-Sync.
Internal memory resource of the MPC5606S allows to easily handle complex graphics contents (pictures, icons, languages,
fonts) on a color TFT panel in up to Wide Quarter Video Graphics Array (WQVGA) sizes. All the data fetches from internal
and/or external memory are performed by the internal four-channel DMA of the DCU providing a high speed/low latency access
to the system backbone.
Control Descriptors (CDs) associated with each layer enable effective merging of different resolutions into one plane to
optimize use of internal memory buffers. A layer may be constructed from graphic content of various resolutions including
1bpp, 2bpp, 4bpp, 8bpp, 16bpp, 24bpp and 24bpp+alpha. The ability of the DCU to handle input data in resolutions as low as
1bpp, 2bpp and 4bpp enables a highly efficient use of internal memory resources of the MPC5606S. A special tiled mode can
be enabled on any of the 16 layers to repeat a pattern optimizing graphic memory usage.
A hardware cursor can be managed independently of the layers at blending level increasing the efficient use of the internal DCU
resources.
To secure the content of all critical information to be displayed, a safety mode can be activated to check the integrity of critical
data along the whole system data path from the memory to the TFT pads.
The DCU features the following:
Display color depth: up to 24 bpp
Generation of all RGB and control signals for TFT
Four-plane blending
Maximum number of Input Layers: 16 (fixed priority)
Dynamic Look-Up-Table (Color and Gamma Look-Up)
blending range: up to 256 levels
Transparency Mode
Gamma Correction
Tiled mode on all the layers
Hardware Cursor
Critical display content integrity monitoring for Functional Safety support
Internal Direct Memory Access (DMA) module to transfer data from internal and / or external memory.

Parallel Data Interface (PDI)
The PDI is a digital interface used to receive external digital video or graphic content into the DCU.
The PDI input is directly injected into the DCU background plane FIFO. When the PDI is activated, all the DCU
synchronization is extracted from the external video stream to guarantee the synchronization of the two video sources.
The PDI can be used to:
Connect a Video Camera output directly to the PDI
Connect a secondary display driver as slave with a minimum of extra cost
Connect a device gathering various Video sources
Provide flexibility to allow the DCU to be used in slave mode (external synchronization)
The PDI features the following:
