Calixto Systems introduces i.MX93 VERSA SO-DIMM SoM and EVK with NXP i.MX 93 Edge AI SoC

India-based Calixto Systems has unveiled the i.MX93 VERSA SO-DIMM system-on-module (SoM) powered by an NXP i.MX 93 Arm Cortex-A55/M33 SoC with Ethos-U65 micro NPU for Edge AI applications, as well as an evaluation kit (EVK).

The system-on-module features up to 2GB LPDDR4x RAM, 16GB eMMC flash, a gigabit Ethernet PHY, and exposes various I/Os through a 200-pin SO-DIMM edge connector, such as MIPI DSI, LVDS, and parallel RGB display interfaces, MIPI CSI and Parallel camera interfaces, dual GbE (on PHY on-module, one on carrier), and more. The i.MX93 VERSA module targets smart industrial automation, healthcare, retail, and connected edge systems with specific size, performance, and power efficiency requirements.

i.MX93 VERSA specifications:

• SoC – NXP i.MX 93
  • CPU
    • Up to 2x Arm Cortex-A55 up to 1.7 GHz
    • 2x Arm Cortex-M33 up to 250 MHz
  • GPU – PXP 2D GPU with blending/composition, resize, color space conversion
  • NPU – Arm Ethos-U65 NPU @ 1 GHz up to 0.5 TOPS
  • Memory – 640 KB OCRAM w/ ECC
  • Security – EdgeLock Secure Enclave
• System Memory – 256MB to 2GB LPDDR4x
• Storage – 4GB, 8GB, or 16GB eMMC flash
• Networking – On-module gigabit Ethernet PHY
• 200-pin SO-DIMM edge connector
  • Storage – 2x SD
  • Display Interfaces – MIPI DSI, LVDS, and Parallel RGB
  • Camera Interfaces – MIPI CSI, Parallel Camera
  • Audio – SAI, PDM
  • Networking – 2x gigabit Ethernet
  • USB – 2x USB 2.0
  • Analog – ADC channels
  • Low-speed I/Os – 8x UART, 8x SPI, 8x I2C, 2x CAN-FD, PWM
• Power Supply – 3.3V DC @ 0.70A
• Dimensions – TBD

There’s nothing much about software on the product page, but the company told CNX Software they provide a Linux BSP featuring U-Boot bootloader, the Linux Kernel, and Yocto Project build system for custom Linux distributions, as well as a Debian-based filesystem. The BSP also includes reference drivers, sample applications, and documentation, and has been fully tested on the VERSA Evaluation Board shown below. The calixto-systems GitHub account may have more for the new module and board later on.

The i.MX93 VESA SOM EVB comes with a Gigabit Ethernet port, a USB 2.0 host and OTG ports, a microSD card slot, MIPI DSI and LVDS display connectors, a MIPI CSI connector, CAN Bus and RS485 interfaces, 12V DC input, 50-pin and 20-pin GPIO headers, debug serial and JTAG connectors, and an RTC with a super capacitor.

The market is already well-served with various NXP i.MX 93 system-on-modules such as Forlinx FET-MX9352-C and CompuLab UCM-iMX93 with board-to-board connectors, iWave Systems iW-RainboW-G50M and ADLINK OSM-IMX93 OSM-compliant modules, the Ronetix RNX-iMX93-SMARC following the SMARC 2.1 standard with a 313-pin MXM edge connector, and other NXP i.MX 93 SO-DIMM SoMs like the VAR-SOM-MX93.

The i.MX93 VERSA SO-DIMM system-on-module just adds to the list, and I could not find any specific selling points/differentiating features compared to competitors. It’s not the first time we have written about the company, as we covered Calixto Systems AM335x-VERSA-SOM on CNX Software back in 2012.

Pricing information has not been made public. The products page has limited additional information about the VERSA family of CPU modules.
