UART
• One channel of UART is available.

I2S Bus Interface (I2S)
• General-purpose I2S audio bus interface with one input and one output channels
• Contains a 24-byte FIFO (24 bits × 2 channels (L & R) × 4).
• Resolution: 16 bits and 24 bits (PCM data output format)
• Clock polarity and data shift direction (MSB first/LSB first) are software configurable.
• Can generate FIFO empty interrupts for the output channel (half empty, whole empty, or one empty) and
FIFO full interrupts for the input channel (whole full or one data).
• Supports DMA transfer.
Card Interface (CARD)
• Generates 8-bit SLC/MLC NAND Flash interface signals.
• Includes a Reed-Solomon codec to support an EDC (Error Detection Code) and an ECC (Error Correction
Code) functions.
• A #CE area can be selected to connect a NAND Flash.
MMC/SD/SDHC Card Interface (SD_MMC)
• SD/SDHC card controller compatible with SD Memory Card Physical Layer Specification Version 2.00.
• MMC controller compatible with MultiMediaCard System Specification Version 2.2.
• Variable clock rate up to 30 MHz.
• Supports 4-bit (wide bus) and 1-bit SD bus interface.
• CRC7 and CRC16 generators
• Supports DMA transfer.
Note:
Please join the SD Association (SDA) when handling SD and SDHC cards.
Infrared Remote Controller (REMC)
• Outputs a modulated carrier signal and inputs remote control pulses.
• Embedded carrier signal generator and data length counter
• Can generate counter underflow interrupts for data transmission and input rising/falling edge detection
interrupts for data reception.
LCD Controller (LCDC)
• Supports STN LCD panels with 4/8-bit data lines or TFT LCD panels with up to 24-bit data lines.
• Supports various panel resolutions, such as 640 × 480 pixels (VGA) and 320 × 240 pixels (QVGA) (can be
configured according to the panel used).
• Supports up to 16M-color (for color TFT), 4K-color (for color STN), and 16-level gray scale (for monochrome
STN) display modes.
• Typical display configuration when the internal VRAM (20KB) is used
- 320 × 240 pixels, 2 bpp (4-level gray scale display)
• Display configuration when an external memory is used
- 320 × 240 pixels, 16 bpp (QVGA 64K-colors display)
- 400 × 240 pixels, 16 bpp (WQVGA 64K-colors display)
- 640 × 480 pixels, 16 bpp (VGA 64K-colors display)
• Two-image overlay display via the Picture-in-Picture Plus function
• Virtual display function to handle images with a different resolution from the LCD panel (any area in the
virtual screen can be displayed on the LCD.)
A/D Converter (ADC10)
• 10-bit successive approximation type A/D converter
• Up to eight analog input channels (chip and PFBGA12U-180 package)
• Up to four analog input channels (TQFP24/QFP20-144pin and TQFP15-128pin packages)
• Conversion time: 10
μs
min. (when 2 MHz input clock is selected) 1,250
μs
max. (when 16 kHz input clock
is selected)
• Can generate conversion completion and data overwrite error interrupts.
USB Function Controller (USB)
• Supports USB2.0 full speed (12M bps) mode.
• Provides auto negotiation function.
• Supports control, bulk, isochronous and interrupt transfers.
• Supports four general-purpose endpoints and endpoint 0 (control).
• Embedded 1K-byte programmable FIFO
• Can generate USB interrupts.
• Supports DMA transfer.
General-purpose I/O Ports (GPIO)
• Maximum 91 I/O ports and eight input ports are available (chip and PFBGA12U-180 package).
