i.MX8M Plus comes in the Qseven form factor

Congatec’s Qseven form factor module “Conga-QMX8-Plus” runs under Linux or Android on the i.MX8M Plus equipped with NPU with up to 6 GB LPDDR4, up to 128 MB eMMC, a microSD slot, GbE with TSN and optional -40 to 85 ° C support.

Congatec announced the first Qseven form factor module we’ve seen to build NXP’s i.MX8M Plus, which it has already implemented in its Conga-SMX8-Plus SMARC module. The Conga-QMX8-Plus, which succeeds earlier Qseven modules in the i.MX8 family, including the i.MX8X-based Conga-QMX8X, runs on Linux, Yocto or Android on the 14 nm quad-core Cortex A53 SoC with 1.8 GHz.

The i.MX8M Plus is also equipped with a Cortex-M7 MCU, Vivante GC7000UL 3D and GC520L 2D GPUs, an 800 MHz HiFi4 DSP, dual ISPs, AES encryption and other security features. The most notable feature, however, is a 2,3 TOPs NPU for AI acceleration.

The announcement came in conjunction with the 15th anniversary of the Qseven form factor that preceded SMARC. The MXM-inspired 70 x 70 mm compute module standard was announced 13 and a half years ago in early 2008 by a Qseven consortium led by Congatec, MSC Vertriebs and Seco. Qseven was officially released in July of this year, with Congatec presenting the first prototype with a Conga QA module based on an Intel Atom Z5xx with 1 GB DDR2 and up to 4 GB SSD in December 2008.

Nowadays you can fit a lot more in a footprint of 70 x 70 mm. The Conga-QMX8-Plus supports up to 6 GB 4000 MT / s LPDDR4, including inline ECC RAM. The module can load up to 64 MB SPI NOR Flash and up to 128 GB eMMC 5.1 memory. There is even a microSD slot.

The Conga-QMX8-Plus is equipped with a GbE controller with IEEE 1588 and TSN support. Other interfaces are dual role USB 3.0, 3x USB 2.0, 2x I2C and 12x GPIO (14x according to the announcement).

The individual I / Os include SDIO, PCIe 3.0, SPI and CAN FD. The specs mention a single UART with handshake, but the announcement says there are 4x UARTs. There is also support for JTAG and an RTC.

Media functions include HDMI 2.0a, which the i.MX8M Plus limits to HD resolution. However, there is an optional “Conga-DP / HDMI Adapter 4k” accessory that Congatec says supports 4K video.

Other display interfaces include dual-channel, 24-bit LVDS, and 4-lane MIPI-DSI, which share a signal with a second LVDS interface. You also get 2x 4-lane MIPI-CSI for up to 12 megapixel resolution and 2x I2S for digital audio.

The Conga-QMX8-Plus is available in the operating ranges 0 to 60 ° C and -40 to 85 ° C (in this case the clock rate drops to 1.6 GHz). There is a tolerance of 10–90% non-condensing relative humidity and the module is operated with 2–5 W power.

Options include heat spreaders, active coolers, an 8MP Basler dart camera, and various cables. Congatec also offers its Conga-QEVAL Qseven carrier board.

“This year we are celebrating the 15th anniversary of Qseven,” said Ansgar Hein, chairman of SGET, the current manager of the Qseven standard. “With this new generation of modules with long-term availability of at least 10 years, I am more than confident that we will also celebrate our 25th anniversary.”
