SOM Adds Cost-Effective Wireless Connectivity
Supporting a diverse range of embedded applications, Direct Insight can now address development for cost-constrained embedded systems requiring integrated wireless connectivity with the QSMP-15W solder-down QFN-style system-on-module (SOM).
The SOM leverages an industrial-grade STM32MP1 MPU and a Murata Wi-Fi + Bluetooth module. It also incorporates an STMicroelectronics’ STM32MP157C microprocessor based on a 650-MHz, dual-core Arm Cortex-A7 and a 209-MHz Arm Cortex-M4 coprocessor, with a dedicated 3D GPU.
Manufactured by Direct Insight’s partner, Ka-Ro Electronics, the module adds 512 MB of DDR3L RAM and 4-GB eMMC flash on a 27- × 27- × 2.3-mm solder-down package with QFN-type pinout and 1-mm pitch. There are 100 edge-located pads for thermal efficiency and EMI minimization. Features include an operating temperature range from –40 to +85°C and a range of I/O interfaces, including CANbus, UART, SPI, I2C, audio, Gigabit Ethernet, SD, USB, and a MIPI-DSI display interface.
Requiring a single 3.3-V supply, the Murata Type 2AE Wi-Fi + Bluetooth module supports dual-band 2.4- and 5-GHz Wi-Fi 802.11a/b/g/n/ac + Bluetooth 5.2 BR/EDR/LE, and its Infineon CYW4373E chipset provides coexistence hardware mechanisms and algorithms. Security and power management features support IoT and industrial applications, with readiness for low-power and CRA-compliant system implementations.
The QSMP-15W comes with a dedicated development system, a Linux board support package, and an available development kit that includes a Molex 2.4/5-GHz balanced PCB antenna.
