Oxfordshire, UK June 2020: Direct Insight, the UK-based, technical systems integrator and reseller of system-on-module (SoM) and other embedded systems, has announced the tiny QSMP Solder-down module with STMicro ST32M1 single/dual core ARM Cortex-A7, manufactured by the company’s long-standing partner, Aachen-based Ka-Ro Electronics. The module’s ST32M1 family processor provides a single or dual 650MHz ARM Cortex-A7 core as well as a separate ARM Cortex-M4 running at 200MHz. Also featured is up to 512MB of DDR3L RAM, up to 4GB eMMC Flash, and a range of interfaces. As well as very low-power operation, the ST32M157C can offer a powerful 3D GPU, secure boot and an AES/TDES/SHA crypto-engine.
The new QSMP SoM measures 27mm square and just 2.3mm high. It features a solder-down package with a QFN-type pin-out based on a 1mm pitch with 100 edge-located pads. This design aids inspection and simplifies routing, even permitting a two-layer baseboard and a base plane. An innovative ground plane design ensures that the modules effectively ‘float’ into position during reflow, unlike a BGA which require X-Ray inspection to ensure full connectivity. Also, these QS solder-down modules are so small that warping does not occur.
The design of the package also improves thermal efficiency and EMI performance as the base functions as both a ground pad and a thermal conductor. Modules operate across an industrial temperature range of -40 or -25 to +85degC.
Comments David Pashley, Direct Insight’s MD: “Solder-down SoMs offer simplicity and reduced cost but can be tricky to handle during production. Ka-Ro’s QS modules address these challenges, simplifying inspection and PCB layout, while delivering huge processing power – all in a miniature package.”
The module features a wide range of connectivity options including CANbus (ST32M153A and ST32M157C), UART (x3), SPI (x2), I2C (x2), Audio, Gb Ethernet, SD, USB Host and Client and a parallel or MIPI-DSI (ST32M157C) display. It requires a single 3.3V supply.
The ST32M1 ARM Cortex-A7-powered QSMP solder-down SoM comes with a dedicated development system, equipped with Linux BSP.
