==== External LCD display (CN8)  ====
[[File:G1E_Connecting-LCD-KIT-B01.png|right|thumb|400px|Connecting LCD-KIT-B01 to the Renesas RZ/G1E Starter Kit board]]
The Renesas RZ/G1E Starter Kit board has a dedicated connector for [http://www.apnet.co.jp/product/xg/items/lcd_kit_b01.html LCD-KIT-B01] touchscreen panel.

[http://www.apnet.co.jp/support/man/lcd_kit_b01.pdf Datasheet] is available in Japanese.

[http://en.wikipedia.org/wiki/I%C2%B2C I<sup>2</sup>C] interface is available for getting touchscreen data.<br clear=all>

=== Audio ===
[[File:G1E_SSI_routing.png|right|thumb|400px|SSI routing on the Renesas RZ/G1E Starter Kit board]]

==== Analog In/Out ====
[http://www.akm.com/akm/en/product/datasheet1/?partno=AK4643EN AKM AK4643] audio codec is integrated on the Renesas RZ/G1E Starter Kit board.

AK4643 is in slave mode after reset and can be switched to master by writing to a special register via the [http://en.wikipedia.org/wiki/I%C2%B2C I<sup>2</sup>C] interface. It is assumed that SSI_DATA0 is set to transmit mode and SSI_SDATA1 is set to receive mode. 

==== HDMI (CN6) ====

=== Debug Interface (CN1) ===
[[File:G1E_Arm-jtag-layout.gif|right|thumb|Pinout of ARM JTAG connector]]
The Renesas RZ/G1E Starter Kit board includes a 20-pin header for attaching a [http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0499b/BEHEIHCE.html ARM JTAG] debugger. TCK, TDI and TMS have internal 1.8V pull-up resistors. An additional resistor can be soldered to the board to add 1.8V pull-up to the ASEBRK pin. Refer to [[Board manual]] for more information.<br clear=all>

=== MicroSD card slot ===
The MicroSD card slot (CN4) is connected to the SD card host interface SDHI1 of the RZ/G1E SoC. When GP4_26 is set to 1, power is supplied. When GP4_26 is set to 0, power is shut off.

=== eMMC ===
8GB eMMC [https://www.micron.com/parts/nand-flash/managed-nand/mtfc8glwdq-3m-ait-z  MTFC8GLWDQ-3M AIT Z] (U5) is installed on the Renesas RZ/G1E Starter Kit board. It is connected to the SoC via 8-bit MMC interface.

eMMC is governed by [http://www.jedec.org/standards-documents/results/jesd84-b50 JESD84-B50 standard].

=== Ethernet ===
The RZ/G1E Starter Kit board has one 10/100 Ethernet port compliant with IEEE 802.3u. [http://www.micrel.com/index.php/en/products/lan-solutions/phys/article/24-ksz8041rnl.html Micrel KSZ8041] (U13) PHY is used, in RMII mode. The port is Auto MDI/MDI-X
Since Ethernet AVB and EthetMAC use same pins of the SoC they cannot be used simultaneously. EtherMAC_B can be used with Ethernet AVB.

=== Video In ===
The Video Input interface on the RZ/G1E Starter Kit board can be used with misc. sources of standard analog baseband television signals compatible with NTSC, PAL. (For example: traditional analog CCTV or car front/rear cameras, media players)

The video signal from the Video In connector is converted with [http://www.analog.com/en/audiovideo-products/video-decoders/adv7180/products/product.html Analog Devices ADV7180] into 4:2:2 component 8-bit ITU-R BT.656 video data and passed to the RZ/G1E SoC VIN0 interface

=== USB ===
[[File:G1E_USB.png|right|thumb|400px|USB connector on the Renesas RZ/G1E Starter Kit board]]
The CN2 USB type A connector has two ports. The upper port is Ch 0 and the lower port is Ch 1. USB 2.0 mode is supported to the corresponding USBx_OVC pin.

In host mode, each port is current-limited at 2.4 A by [http://www.rohm.com/web/eu/products/-/product/BD82065FVJ ROHM BD82065FVJ]. Overcurrent is reported to the Renesas RZ/G1E SoC.

==== USB Host ====
USB host mode is possible for both Ch 0 and Ch 1. For Ch0, SW10 should be switched to pin 1 side.

==== USB Function ====
USB function mode is possible for Ch0 when SW10 is set to pin 3 side. VBUS from CN2/lower is routed to USB0_OVC/VBUS pin of the Renesas RZ/G1E SoC.

Refer to [[RZ/G1E Starter Kit hardware manual]] for more information.<br clear=all>

=== Debug Serial (CN13) ===
The Renesas RZ/G1E SoC debug interface SCIF2 is exposed to the microUSB connector (CN13) via [http://www.silabs.com/support%20documents/technicaldocs/cp2102-9.pdf Silicon Labs CP2102]. Refer to [[RZ-G/Boards/SK-RZG1E#Booting_over_TFTP_from_U-Boot]] for configuring and using the interface.

CP2102 is self powered and requires no power over USB. Keep in mind that CP2102 will not be detected by the host PC until the Renesas RZ/G1E Starter Kit board is connected to 5 V power source.

=== EXIO (JP1, JP2) ===
[[File:G1E_EXIO.png|right|thumb|upright|Pin locations on EXIO connectors (JP1, JP2) of the Renesas RZ/G1E Starter Kit board]]
The Renesas RZ/G1E Starter Kit board includes two EXIO connectors. Both are "Box Wafer, 2.0-mm pitch".

JP1 has [http://en.wikipedia.org/wiki/I%C2%B2C I<sup>2</sup>C] interface, connected to SDA3/SCL3 of the Renesas RZ/G1E SoC.
