• 1, 2, or 4 bits-per-pixel (bpp) palettized displays for monochrome STN.
• 1, 2, 4, or 8 bpp palettized color displays for color STN and TFT.
• 16 bpp true-color non-palettized for color STN and TFT.
• 24 bpp true-color non-palettized for color TFT.
• Programmable timing for different display panels.
• 256 entry, 16-bit palette RAM, arranged as a 128 32-bit RAM.
• Frame, line, and pixel clock signals.
• AC bias signal for STN, data enable signal for TFT panels.
• Supports little and big-endian, and Windows CE data formats.
• LCD panel clock may be generated from the peripheral clock, or from a clock input
pin.
7.15.2 SD/MMC card interface
The SD/MMC card interface supports the following modes to control:
7.15.2.1 Features
• Secure Digital memory (SD version 1.1).
• Secure Digital I/O (SDIO version 2.0).
• Consumer Electronics Advanced Transport Architecture (CE-ATA version 1.1).
• MultiMedia Cards (MMC version 4.1).
• Supports up to a maximum of 50 MHz of interface frequency.
7.15.3 External memory controller
The LPC540xx EMC is an ARM PrimeCell MultiPort Memory Controller peripheral offering
support for asynchronous static memory devices such as RAM, ROM, and flash. In
addition, it can be used as an interface with off-chip memory-mapped devices and
peripherals. The EMC is an Advanced Microcontroller Bus Architecture (AMBA) compliant
peripheral.
7.15.3.1 Features
• Read and write buffers to reduce latency and to improve performance.
• Low transaction latency.
