New Quad Core Cortex-A53 System-On-Module supports DDR3/DDR3L/DDR4 memories from 1 up to 4GB

Our RK3328-SOM prototypes are testing now.

These are with dimensions of only 55 x 41 mm.

RK3328 SOC has:

  • 4x Cortex-A53 cores @1.5Ghz
  • DDR3/DDR3L/DDR4 support 1/2/4GB
  • GPU: ARM Mali-450MP2
  • HDMI 2.0
  • CSI up to 5Mpix
  • Video decode H.264 H.265 4K@60Hz
  • Video encode H.264 H.265 1080p@30Hz
  • Audio: I2S, Codec
  • Gigabit 10/100/1000 Ethernet
  • Megabit 10/100 Ethernet with PHY
  • USB3.0 host
  • USB2.0 host
  • USB-OTG 2.0
  • SPI/eMMC Flash
  • SD-card

RK3328-SOM-EVB is evaluation board and reference design for RK3328-SOM:

Software support:

  • Android 10
  • Linux Kernel 4.4 is the official SDK of Rockchip. There is just basic mainline support with no drivers for USB3 although these SOCs are on the market for quite a lot of time.

The preliminary prices are:

  • RK3328-SOM-1G (1GB DDR3L) EUR 27.00
  • RK3328-SOM-2G (2GB DDR3L) EUR 37.00
  • RK3328-SOM-4G (4GB DDR4) EUR 57.00
  • RK3328-SOM-EVB (no SOM installed) EUR 18.00

SOM204 is SODIMM form factor System-On-Module we are working for a while (actually from so long time ago that SOM204-EVB platform is made in Eagle which we dropped to use officially from quite some time ago).

The SODIMM connector has these signals:

  • Power supply: +5V, GND, LiPobattery, RTC_backup, Stepup-Output, Stepup-enable, USB+5V
  • Interfaces: Gigabit Ethernet, Megabit Ethernet, CAN, SATA, PCIe, USB2.0 HOST x2, USB-OTG, USB3.0 HOST, HSIC, UARTx3, SPIx2, I2Cx2, CSI, microSD, GPIOs with interrupts,
  • Display: HDMI, VGA
  • Audio: SPDIF, Line-in/out, Microphone, Headphone.

You can see complete SOM204 platform signals here.

The idea behind SOM204 is to make Universal interchangeable SOM with different performance and resources.

Our first SOM204 module is with A20 processor, it’s now in production and will be available for purchase next week.

The second SOM204 module is with A64, the third is with RK3328 which we expect to be ready for production around June. Next to follow is AM335X which will be ready by end of the year together with RK3399. The goal is to have 5 different modules by the end of the year.

A20-SOM204 comes with 1GB RAM, optional SPI Flash or eMMC Flash up to 64GB, two native Ethernets (this is the only A20 board with dual native Ethernets) Gigabit and Megabit, SATA and so on. The USB3.0 interface and PICe interfaces are not wired. On top on SOM204 platform LCD and additional GPIOs are exposed on FPC connectors:

The A20-SOM204 schematic is here.

A20-SOM204-EVB is evaluatuon board with A20-SOM204SOM204-EVB2

A20-SOM204 software is Armbian with mainline kernel and support for all SOM peripherials.
