1.1.4

External Memory Interface

Item

Description

External Bus Controller for

DDR3L SDRAM (DDR)

● Support DDR3L-1600

● Bus Width: 16-bit

● Memory Size: 128M Bytes

● Auto Refresh supported

SPI Multi I/O Bus Controller

● 1 channel (4-bit Double data rate)

● 1 serial flash memory with multiple I/O bus sizes (single / quad) can be connected

● External address space read mode (built-in read cache)

● SPI operation mode

● Maximum Clock Frequency:

– 50 MHz (Quad-SPI DDR)

– 66 MHz (Quad-SPI SDR)

SD Card Host Interface(SD)

● 1 channel

● Channel 0 supports SDHI

● SD memory I/O card interface (1-bit / 4-bit SD bus)

● SD, SDHC and SDXC SD memory card access supported

● Compliant with SD 3.0

● Default, high-speed, UHS-I/SDR50, SDR104 transfer modes supported

● Error check function: CRC7 (Command), CRC16 (Data)

● Card detection function, write protect supported

Note 1. This LSI is a SiP (system in package) with build-in DDR3L SDRAM, so customers cannot use DDR interface.

1.1.5

Video Processing Unit

Item

Description

2D drawing engine

(DRW)

● Support almost any object geometry, rather than being bound to only a few specific geometries

such as lines, triangles, or circles. The edges of every object can be independently blurred or

anti-aliased

● Color Formats

Frame buffer formats

8-bit: a (8)

16-bit: RGB (565), aRGB (4444), aRGB (1555)

32-bit: aRGB (8888)

Texture formats

1-bit: CLUT (1) / I (1)

2-bit: CLUT (2) / I (2)

4-bit: CLUT (4) / I (4)

16-bit: aRGB (4444), aRGB (1555), RGB (565)

24-bit: RGB (888) (run length encoded (RLE) unit)

32-bit: aRGB (8888).

CLUT formats use a 256-entry color lookup table.
