Compact Renesas RZ/G1C based ARM Linux Single Board Computer Exposes 100 Expansion Pins

Orange Pi Development Boards

iWave Systems has released a new business card sized single board computer (SBC) with iW-RainboW-G23S, which looks somewhat similar to a Raspberry Pi 3 board, but is equipped with Renesas RZ/G1C single or dual core ARM Cortex A7 processor, up to 2GB RAM, Gigabit Ethernet, and provides plenty of I/Os through 3 headers for a total of 100 pins.

Target applications include HMI & access control, industrial control, healthcare devices, point of sale, IoT, home & office automation, and white goods & appliances.

iW-RainboW-G23S board specifications:

  • SoC – Renesas RZ/G1C Dual/Solo ARM Cortex-A7 processor @ 1.0 GHz with PowerVR SGX531 3D GPU
  • System Memory – 512 MB DDR3 (expandable up to 2GB)
  • Storage – 2MB SPI Flash  (expandable), 8GB eMMC Flash (expandable), and micro SD connector
  • Video Output/Input – 1x HDMI output port,  1x CVBS input RCA jack, optional 1x CVBS output RCA jack/header
  • Video – HD encode/decode
  • Connectivity – 100/1000Mbps Ethernet
  • USB – 2x USB 2.0 host ports, 1x micro USB OTG port
  • Expansion Headers
    • 40-pin connector 1 compatible with Raspberry Pi 3 header with 1x UART, 1x SPI, 2x SPI, 17x GPIOs
    • 40-pin connector 2 with 1x LVDS, 1x CAN, 2x I2S/SSI, 2x UART (with CTS & RTS), 1x UART (without CTS & RTS), 1x I2C, 1x PWM
    • 20-pin connector 3 with debug UART, 1x UART (without CTS & RTS) or 1x I2C, 1x 8-bit parallel camera interface (VIN0), 1x PWM
  • Misc – JTAG header, SPI flash programming header, Reset switch, RTC controller with coin cell battery (optional)
  • Power Supply – 5V/2A with optional power input lockable header
  • Dimensions – 85mmx 56mm
  • Temperature Range – -20 to +85° C
  • Compliance – REACH & RoHS Compliant;  CE, FCC certification in progress

We don’t have a whole lot of information about software support except the company provide a Linux BSP based on the not-so-recent Linux 3.10.31.  Renesas recently announced a Super Long Term Kernel with 10-year of support based on CIP Linux 4.4 for RZ/G processors,  starting with RZ/G1M, and plans for other RZ/G1 SoCs in the future, so hopefully RZ/G1C will be covered eventually, but there’s no guarantee. [Update: RZ/G1C support is coming in H1 2018]

Strange they release a new board with an old 1Gh A7 cpu.

Hmmm, not totally surprised, I bet it’s meant to test out and develop around a CPU that will carry long term support, which is a strong point for some industries.
I have family at airbus, they are at last allowed to have 68k cpus and old but hardened powerpc chips 🙂

Oh look, a GPU that’s actually worse than the ARM Mali 400…
This is a bizarre SoC on a bizarre board…

too bad they ditched their excellent SH-core series

dual cores are mostly not produced anymore, at least not in the tablet/smartphone/setopbox markets.

Really not sure what the problem with a cortex A7 is. The article says the target market is white goods etc.. why would you need anything else?
