CompuLab has introduced the UCM-iMX952, a 28 x 40mm System-on-Module based on NXP’s i.MX952 processor. The module supports up to 16GB of LPDDR5 or LPDDR4X memory and 128GB of eMMC storage, along with PCIe Gen 3, 2.5GbE, Wi-Fi 6, Bluetooth 5.4, and multiple display and camera interfaces.

The NXP i.MX952 is available on the module in dual- or quad-core Arm Cortex-A55 configurations, with clock speeds up to 1.7GHz. The processor also integrates an Arm Mali-G310 GPU supporting OpenGL ES 3.2, Vulkan 1.2, and OpenCL 3.0, along with a 4K video processing unit and an eIQ Neutron NPU for machine-learning acceleration.

Real-time and low-power processing is handled by Arm Cortex-M7 and Cortex-M33 cores, operating at up to 800MHz and 333MHz, respectively.

Memory configurations range from 4GB to 16GB using LPDDR5 or LPDDR4X connected through a 32-bit interface. Onboard eMMC storage is available in capacities from 16GB to 128GB and is used for the bootloader, operating system, and general-purpose data.

Display connectivity includes two four-lane LVDS interfaces that can alternatively operate as a single eight-lane interface, supporting resolutions up to 1080p60. The four-lane MIPI-DSI interface supports up to 4K30 or 3840 x 1440 at 60Hz, with a maximum data rate of 2.5Gbps per lane.

For camera applications, the module provides MIPI-CSI connectivity configurable as either one four-lane interface or two two-lane interfaces. Digital audio support includes up to five SAI interfaces for protocols such as I2S, AC97, TDM, and codec/DSP connections.

Networking options include 2.5GbE through an SGMII interface and an optional 10/100/1000Mbps Ethernet PHY. The 2.5GbE interface shares its signals with PCIe Gen 3 x1, while a separate RGMII interface is available for connecting an external Ethernet PHY.

Optional wireless connectivity is provided through an Ezurio SONA NX611 module based on the NXP IW611 chipset. It supports IEEE 802.11ax Wi-Fi and Bluetooth 5.4 and connects to the processor through SDIO. Two MHF4 connectors are provided for 2.4GHz Wi-Fi/Bluetooth and auxiliary 2.4/5GHz Wi-Fi antennas.

Other interfaces include two USB 2.0 ports, up to eight UARTs, three CAN-FD interfaces, eight SPI buses, six I2C interfaces, two SD/SDIO interfaces, six PWM signals, eight ADC channels, and up to 94 GPIOs. Many of these signals are multiplexed across the module’s carrier-board connectors.

CompuLab also provides the SB-UCM-iMX95 carrier board for evaluation and development. Display connectivity includes an LVDS interface supporting up to 1366 x 768 at 60Hz and a MIPI-DSI interface supporting up to 1920 x 1080. Headers are also provided for capacitive touchscreens.

Camera support consists of two two-lane MIPI-CSI interfaces exposed through an edge connector. Raspberry Pi camera modules can be connected using CompuLab’s optional EB-EVCAMRPI adapter. Analog audio is provided through a WM8962 codec with separate 3.5mm line-in and line-out jacks.

The carrier board provides two Gigabit Ethernet ports and a mini-PCIe socket for cellular modems, accompanied by an onboard micro-SIM socket. Expansion options also include an M.2 Key-M socket for NVMe storage, a microSD slot, and two USB 2.0 Type-A ports.

Additional interfaces are exposed through 100-mil headers, including two UARTs, CAN/CAN-FD, SPI, I2C, and up to 16 GPIOs. Debug and programming features include a micro-USB serial console, JTAG header, two programmable user LEDs, and a separate micro-USB connection supporting NXP’s SDP/UUU programming protocol.

For software, CompuLab lists Debian Linux, Yocto Project, and RTOS support, along with Board Support Packages, Linux kernel support, U-Boot, and ready-to-run images. The company also lists support for Docker, Microsoft Azure IoT, Node-RED, and Mender-based OTA updates.
