RZ-G/Boards/SK-RZG1E:Hardware

This page contains information on the RZ-G/Boards/SK-RZG1E hardware.

Power Plug
The RZ/G1E Starter Kit board uses a 5.5 x 2.1mm barrel 5V power plug. It is a Center Positive power supply, indicating that the center (tip) of the output plug is positive (+) and the outer barrel is negative (-).

SW1 (SSI_DATA1 Routing)
SW1 selects the device to be connected to the SSI_DATA1/ETH_RXD0_B (GP-5-13) pin of the the RZ/G1E SoC. The pin is normally set to receive mode.

SW2 (TRST# Pull-up)
SW2 selects whether to pull up or down the TRST# pin of the RZ/G1E SoC JTAG interface.

SW3, SW4, SW6 (Push Buttons)
The active signal (low or high) for SW3-SW5 is selected by the corresponding bit of POSNEG register. Refer to to the section GPIO in the RZ/G1E Hardware Manual for details.

SW7 (Mode Setting A)
MD21 determines the JTAG mode. Select OFF position to use JTAG debugger. MD19 determines the SDRAM clock speed. It must remain in OFF position to select DDR3-1333.

SW9 (SPI Flash Memory Selection)
The RZ/G1E Starter Kit board is equipped with 512 Mbits SPI flash memory (U6: S25FL512SAGMFIG11) and 32 Mbits SPI flash memory (U7: S25FL032P0XMFI011). When SW9 is set to the pin 1 side, the SSL pin of the RZ/1GE SoC to the 512 Mbits flash memory. When SW9 is set to the pin 3 side, the SSL pin of the RZ/G1E SoC to the 32 Mbits flash memory.

SW10 (USB2.0 Channel 0 Host or Function Selection)
SW10 selects the mode of USB port 0 located on top of the USB connector.

SW12 (User-Defined Software Switch)
Before using SW12 as a general-purpose input switch, set up the GPSR3 register of the RZ/G1E SoC to select the GPIO function and set the PUPR3 register to enable pulling up. For details, refer to the section on the Pin Function Controller (PFC) in the RZ/G1E Hardware Manual.

LEDs
LD1 (blue): indicates that 5V power has been applied to the board.

LD2 (red): indicates that the board is turned on and has 3.3V power.

Turning On and Off
Special sequence is required for turning on and off the power supply to the RZ/G1E Starter Kit board:
 * To turn ON: Press SW11 once
 * To turn OFF: Long press SW11

HDMI (CN6)
The digital RGB888 signal from the RZ/G1E SoC DU0 is connected to Analog Devices ADV7511 HDMI transmitter. The internal registers of ADV7511 are accessible via I2C interface (slave addresses: 0x72 for writring, 0x73 for reading).

The following displays have been tested with the RZ/G1E Starter Kit board:
 * Gechic On-Lap1502I Touch Monitor (Don't forget to set CONFIG_HID_MULTITOUCH and connect USB touchscreen)
 * Lilliput 10' with capacitive touch screen (NOTE: picture quality is not good due to limited native resolution]
 * Xenarc 7' capacitive touch

VGA (CN9)
The digital RGB666 signal from the RZ/G1E SoC DU1 is connected to Analog Devices ADV7123 video D/A converter. This signal is then feed to the CN9 VGA connector.

The following displays have been tested with the RZ/G1E Starter Kit board:
 * Gechic On-Lap1502I Touch Monitor (Don't forget to set CONFIG_HID_MULTITOUCH and connect USB touchscreen)

External LCD display (CN8)
The Renesas RZ/G1E Starter Kit board has a dedicated connector for LCD-KIT-B01 touchscreen panel.

Datasheet is available in Japanese.

I2C interface is available for getting touchscreen data.

Analog In/Out
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 I2C interface. It is assumed that SSI_DATA0 is set to transmit mode and SSI_SDATA1 is set to receive mode.

HDMI (CN6)
TBD Describe Audio Out through HDMI connector

Debug Interface (CN1)
The Renesas RZ/G1E Starter Kit board includes a 20-pin header for attaching a 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.

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 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 JESD84-B50 standard.

Ethernet
The RZ/G1E Starter Kit board has one 10/100 Ethernet port compliant with IEEE 802.3u. 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 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
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 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.

Debug Serial (CN13)
The Renesas RZ/G1E SoC debug interface SCIF2 is exposed to the microUSB connector (CN13) via Silicon Labs CP2102. Refer to RZ-G/Boards/SK-RZG1E 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)
The Renesas RZ/G1E Starter Kit board includes two EXIO connectors. Both are "Box Wafer, 2.0-mm pitch".

JP1 has I2C interface, connected to SDA3/SCL3 of the Renesas RZ/G1E SoC.

U17 - Placeholder
U17 can be used to connect Apple Authentication IC (I2C4 on the RZ/G1E)
