The TQMa117xL, based on the i.MX RT1170 CPU from NXP, measures just 31x31 mm and provides all signal pins via a total of 240 LGA pins. The module is equipped with sufficient external memory, an optional security chip and a PMIC connected to the CPU. It therefore meets the highest demands. Thanks to the versatility of the processor and the very good power dissipation of less than one watt, this module design already promises multiple applications in many control systems.

With this module, TQ is developing a new LGA module based on the i.MX RT1170 MPU from NXP. This new generation of the i.MX RT processor family from NXP is also known as a crossover CPU, as it bridges the gap between CPU and MPU. A powerful Cortex-M7 core with up to 1GHZ CPU frequency, supported by a Cortex-M4 core with up to 400MHZ and many interfaces, e.g. Gigabit Ethernet, CAN FD, USB 2.0, UART and SPI, are built into the peripherals of the MPU. The module is also equipped with a graphics processing unit (GPU) with 2D support. An external PMIC (Power Management IC), which is independent of the CPU, ensures reliable, high-performance module operation even at higher temperatures.

The TQMa117xxL is equipped with a 16-bit wide LP-SDRAM, which allows a memory expansion of up to 64 GB. A Quad SPI NOR flash memory with a capacity of up to 256 MB is used as the fixed memory. Further system components such as an external and therefore energy-saving real-time clock (RTC), a user EEPROM memory and a temperature sensor round off the module design. Free RTOS - including many application examples - is implemented as the operating system. The SE050 security chip is available as an assembly option for applications that require increased security functions. The module is soldered directly to the mainboard using LGA technology and is therefore also suitable for applications that require a very flat and robust design. The first available samples are planned for mid-August 2021.

"As a long-standing partner of NXP, we are delighted to be able to offer a cost-effective module based on this powerful crossover CPU. This new development offers an ideal platform for applications such as small gateways, room controls, decentralized intelligence in automation, time recording systems or even voice-controlled elevator control," explains Konrad Zöpf, the responsible product manager at TQ.

Adapted to the numerous application possibilities of the TQMa117xL, TQ is also developing a suitable mainboard in parallel with the module. In addition to various interfaces such as two Gigabit Ethernet, two USB 2.0 and two CAN FD galvanically isolated and an SD card interface, four digital 24V inputs/outputs are also implemented to control external peripheral devices. The mainboard is extended with an analog front end from NXP (NAFE13388B40BS). This allows up to eight programmable analog inputs to be used. The connection of touch displays with a resolution of up to 1280x800 pixels is possible via a MIPI-DSI or alternatively an LVDS interface.

The mainboard, which measures just 160 x 100 mm, also scores points with a WiFi and mobile radio option, scalable from LTE to Nero band, for wireless communication. Three user LEDs and a CSI interface with two lanes for camera connection as well as the option of supplying the industrial-grade mainboard via Ethernet complete the design. The SBC (Single Board Computer), consisting of a soldered LGA module and mainboard, can already be used as a fully qualified industrial board thanks to its many functions. It can also be used as the basis for your own designs: from smart HMI solutions in building automation to decentralized intelligence for controlling functions and real-time recording of sensor data in automation.
