iWave unveils the RZ/G1C Single Board Computer
iWave’s new iW-RainboW-G23S RZ/G1C SBC runs Linux on a Renesas RZ/G1C, power efficient Dual core ARM Cortex A7 CPU @ 1GHz. The iW-RainboW-G23S is the industry’s first SBC launched based on Renesas RZ/G1C SoC, which debuted earlier this year.

RZ G1C Single Board Computer

The power-efficient RZ/G1C SoC integrates the 3D capable PowerVR SGX531 GPU and support full high-definition video encoding and decoding, making them ideal fit for human-machine interface (HMI) applications. Other target applications include Access Control, Industrial Control, Healthcare devices, Point of sale, IoT, Home & Office automation and White goods & appliances.
The iW-RainboW-G23S supports up to 2GB DDR3 and 8GB or more of eMMC, plus a microSD slot and SPI flash. The SBC has 2x USB 2.0 host ports, Gigabit Ethernet port, micro-USB port and HDMI port are also supplied, along with a CVBS input jack and optional CVBS output. The board supports dual 40Pin expansion connector where additional IO interfaces like LVDS display, CAN, UART and GPIO ports are supported. For development purpose JTAG connector and serial console also supported in the SBC. A third 20-pin connector includes serial debug and other interfaces.
The features of the SBC are as follows:
Renesas’ RZ/G1C Dual/Solo ARM Cortex™-A7 MPCore™ cores @ 1GHz
DDR3 SDRAM – 512 MB (Expandable Up to 2GB)
eMMC Flash - 8GB (Expandable)
