DDR3 SDRAM
Renesas R-Car M2 Porter board DDR3-1600 RAM is organised into four 4-Gbit DDR3-SDRAMs (2 channels x 32 bit).

128 MB NOR
1 Gbit NOR flash S29GL01GP is available on R-Car M2 Porter board. Full 128 MB are addressable only if CS1 is used for the most significant bit of the address. Otherwise only 64 MB are addressable.

Note: QSPI pins are multiplexed with the higher-order address pins (A20 to A25) of the LBSC due to the specifications of the R-CarM2W’s pin function controller. Accordingly, when the QSPI is in use, only the lower-order address pins (A0 to A19) of the LBSC are available for use. 2 MB are addressable with CS1 and 1 MB without CS1. Refer to SW18.

64 MB SPI
64 MB Spansion S25FL512SAGMFIG11 SPI Flash is available if SW18 is set. Maximum clock rate for SPI is 48.75 MHz.

Video Out
R-CarM2 incorporates one display unit (DU) with the LVDS interface and one display unit with the digital RGB interface.

HDMI (CN45)
Digital RGB888 signal from E-Car M2's DU1 is connected to Analog Devices ADV7511 HDMI transmitter. Internal registers of ADV7511 are accessible via I2C interface (slave addresses: 0x72 for writring, 0x73 for reading).

The following displays have been tested with SILK board: TBD

LVDS (CN30)
DU_LVDS channel 0 of R-car M2 is connected directly to the LCD connector. TBD

Video In (CN15)
Video Input interface on Porter board could be used for misc. sources of standard analog baseband television signals compatible with NTSC, PAL. (For example: traditional analog CCTV or car front/rear cameras, media players)

Video signal from Video In connector is converted with Analog Devices ADV7180 into 4:2:2 component 8-bit ITU-R BT.656 video data and passed to R-Car M2 VIN0 interface
