New Lantronix SIPs use Qualcomm QCS2290 and QCS4290 SoCs

Feb 15, 2023 — by Giorgio Mendoza 590 views

Lantronix released this month two System-in-Package modules based on Qualcomm System-on-Chip Technology. The Lantronix Open-Q SIP modules are equipped with the Qualcomm Adreno GPU, LPDDR4 RAM, eMMC Flash storage, camera support, GNSS, Wi-Fi 5/BT 5.0 connectivity and many other peripherals.

The Open-Q 2290 Series SIP is described as an entry-tier embedded solution which features the Qualcomm QCS2290 with 11 nm process node.  


  •  QCS2290 – 64-bit Quad-core Arm Cortex-A53 (up to 2.0 GHz) w/ DSP; 64-bit Qualcomm Adreno GPU 702 (Up to 845MHz); 1080p @30 fps encode / 1080p @30fps decode           

This SIP (LGA form-factor) is available in a single configuration: 2GB LPDDR4 & 16GB eMMC 5.1. The Open-Q 2290 also supports MicroSD cards for external storage.

The Open-Q 2290 camera interface can handle two 13MP cameras @30fps or one 25MP camera @30fps. The display interface offers one 4-lane DSI D-PHY 1.2 with resolution up to 1680×720 @60fps.  

The datasheet indicates that the Open-Q 2290CS includes a WGR7640 (Qualcomm) RF IC for GNSS support and a WCN3950 chip for 802.11 a/b/g/n/ac Wi-Fi and Bluetooth 5.0 connectivity.

On the other hand, the Open-Q 4290 SIP measures about 36mm x 36mm x 2.76mm and it aims at advanced AI vision applications.

  •  QCS4290 – 64-bit Octa-core Arm Cortex-A53 (up to 2.0 GHz) w/ DSP  Qualcomm Hexagon Vector Processor (Up to 1GHz); 64-bit Qualcomm Adreno GPU 610 (Up to 950MHz); Up to 1080p 60fps encode / 1080p 60fps decode 

Unlike the previous variant, the Open-Q 4290 can be ordered with 2GB LPDDR4/ 16GB eMMC, 4GB LPDDR4/ 64GB eMMC and 4GB LPDDR4/ 256GB eMMC.

The brief for the Open-Q 4290 specifies that this is a Wi-Fi 5 solution with Wi-Fi 6 features: Target Wake Time (TWT) & 8SS. This variant also includes the WGR7640 RF receiver for GNSS functionality.

The camera interface consists of three 4-lane CSIs while the display interface provides one 4-lane MIPI DSI supporting D-PHY 1.2 (1.5 Gbps/lane). The QCS4290 and the QCS2290 support up to 4x DMIC interfaces for digital microphones. The Open-Q 4290 also includes 3x Analog mic inputs, headphone, line-out and speaker outputs.

Both Open-Q variants support standard protocols such as USB 3.1 Type-C, UART, I2C, I3C, SPI and configurable GPIOs. Additionally, the Open-Q 4290 seems to support 4-bit SD.

Lantronix is also selling a companion Open-Q AL Development Kit compatible with both Open-Q chipsets to accelerate product development. Some of the key features of this board include 1x HDMI Type-A, 1x Gigabit Ethernet (via USB 3.0), 1x MicroSD card, 2x 4-lane MIPI CSI, etc. Refer to the block diagram and the table above for complete details.
