LH79524/LH79525
DMA Controller
ble peripherals. The LCD controller uses its own DMA
port, connecting directly to memory for retrieving dis-
play data.
• Simultaneous servicing of up to 4 data streams
• Three transfer modes are supported:
• Identical source and destination capabilities
• Transfer Size Programmable (byte, half-word, word)
• Burst Size Programmable
• Address Increment or Address Freeze
• Transfer Error interrupt for each stream
• 16-word FIFO array with pack and unpack logic
transfers from input to output.
Color LCD Controller (CLCDC)
drive signals to interface directly with a variety of color
and monochrome LCD panels.
• LH79524 has 16 LCD Data bits; LH79525 has 12
• Supports single and dual scan color and mono-

ADVANCED LCD INTERFACE
connection to ultra-thin panels that do not include a tim-
ing ASIC. It converts TFT signals from the Color LCD
controller to provide the proper signals, timing and levels
for direct connection to a panel’s Row and Column driv-
ers for AD-TFT, HR-TFT, or any technology of panel that
allows for a connection of this type. The Advanced LCD
Interface peripheral also provides a bypass mode that
allows the LH79524/LH79525 to interface to the built-in
timing ASIC in standard TFT and STN panels.
Synchronous Serial Port (SSP)

eral devices that support protocols for Motorola SPI,
