SMARC® 2.0 – Innovation meets backward compatibility

What´s new?

The new computer-on-module standard SMARC® 2.0 supports up to four digital displays. A new DP++ (Dual-mode DisplayPort) interface to support resolutions up to Ultra HD/4K with 3840 × 2160 pixels was added. It can be used to connect DisplayPort, HDMI and DVI displays. The single-channel LVDS interface in SMARC® 1.1 was upgraded to dual-channel LVDS in 2.0. This interface can drive either two low-resolution or one high-resolution display. Depending on which processor is used, the interface can support up to 1920 x 1200 pixels at 60Hz. Since the HDMI/DP interface remains unaltered, developers can connect up to three high resolution digital displays via modern serial display interfaces. Existing carrier boards with single channel LVDS and HDMI can be used with SMARC® 2.0 just as before.

New I/Os of the SMARC® 2.0 standard

Furthermore, the number of USB interfaces has been increased significantly. The SMARC® 2.0 standard supports up to six USB 2.0 ports and two USB 3.0 interfaces. Also it supports two GbE interfaces including IEEE1588 trigger signals. Four instead of three PCIe lanes are available for platform-specific extensions, which increases the flexibility for individual function extensions. Three of these PCIe lanes are backward compatible with SMARC® 1.1. One of the two SPI buses has been upgraded to eSPI/SPI and instead of triple I2S (I2S2 for HDA option) and SPDIF, 1x I2S (for ARM designs) and 1x HDA (for x86 designs) are now supported.

What has not been changed is the support of 1x SATA, 12x GPIO, 2x CAN, 1x SDIO (4bit), 4x UART, 1x HDMI, 1x SPI and 4x I2C.
