Single core Cortex

iWave has added an NXP i.MX 91 option to its iW-RainboW-G50M family of OSM v1.1

iWave has added an NXP i.MX 91 option to its iW-RainboW-G50M family of OSM v1.1 solderable LGA system-on-modules.

These recently introduced processors flesh-out the low end of NXP's i.MX 9x range with a single Arm Cortex-A55 core, intended to run Linux in edge devices.

As well as the 45 x 45mm (size L) system-on-module, iWave has created a 100 x 72mm Pico-ITX single-board computer built around the module. Both module and board are specified over the industrial -40 to +85°C temperature range.

Alongside the processor, running up to 1.4GHz, the IC has a security enclave that offers life-cycle management, tamper detection and secure boot. There is also dual Gigabit Ethernet (one with time-sensitive networking) and dual USB ports.

This is joined on the module by 2Gbyte LPDDR4 RAM, 16Gbyte eMMC flash, a 4bit SD interface, Wi-Fi 6, Bluetooth 5.3 and IEEE802.15.4.

It has "provision for 662 contacts, offering the highest pin-to-area ratio across SoM standards", said iWave. "The ability to directly solder the SoM on to the carrier card ensures high levels of robustness. [It] is ideal for products prone to vibrations."

To the above, the single-board computer (left), which doubles as an evaluation board, adds a GNSS receiver for GPS, Glonass, Galileo and BeiDou, dual Ethernet connectors, multiple USB connectors (2.0 OTG microAB, dual TypeA 2.0 Host and Type-C), a Micro SD slot, 3.5mm audio in-out, a Key B M.2 slot, RS232 on a header and an expansion connector with UART, CAN, ADC and PWM.

A board support package is available, and "iWave maintains a product longevity program and ensures the availability of the modules for 10+ years", it said.

Applications are foreseen in smart factories, smart homes, medical devices and smart metering.

In April, iWave released robot software ROS 2 for its similar i.MX 8 Pico-ITX single-board computers.
