After all, engineers who needed Wi-Fi didn\u2019t wait for the ST67W611M1. They just got a device from a third party and installed it onto their PCB.\u00a0<strong>The problem was that we also heard from engineers who complained that this approach was complex, costly, and far from optimal.<\/strong>\u00a0Not all Wi-Fi modules are created equal. Not all drivers are straightforward. And IoT devices are continually seeking to enhance their power efficiency. Put simply, when ST and Qualcomm Technologies announced their collaboration, the feedback we got was overwhelmingly positive.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"thecollaborativesolution\">The collaborative solution<\/h3>\n\n\n\n<p>A practical example of the fruit of the collaboration between ST and Qualcomm Technologies is the integration of the ST67W611M1 into our ecosystem.&nbsp;<strong>In a nutshell, the RTOS communicates with the Wi-Fi module using the SPI protocol; however, developers only need to use simplified API abstraction layer commands.<\/strong>&nbsp;Moreover, we provide examples to help them get started. And while we don\u2019t ship all BLE profiles in our software packages, as it would make them too onerous to download, developers can rapidly add the relevant ones to their application. Consequently, we didn\u2019t just simplify the integration of the device, but also its usage. For instance, writing a basic MQTT application only takes a few hours.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"thest67w611m1journey\">The ST67W611M1 journey<\/h3>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-full\"><img decoding=\"async\" width=\"400\" height=\"345\" src=\"https:\/\/electronicsmaker.com\/wp-content\/uploads\/2025\/08\/ST67-perspective-recto.jpg\" alt=\"\" class=\"wp-image-80831\" srcset=\"https:\/\/electronicsmaker.com\/wp-content\/uploads\/2025\/08\/ST67-perspective-recto.jpg 400w, https:\/\/electronicsmaker.com\/wp-content\/uploads\/2025\/08\/ST67-perspective-recto-300x259.jpg 300w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><figcaption class=\"wp-element-caption\">The ST67W611M1A6P<\/figcaption><\/figure><\/div>\n\n\n<p>To help integrators take advantage of the new device as rapidly as possible, we released the\u00a0<strong>X-NUCLEO-67W61M1<\/strong>\u00a0expansion board and the\u00a0<strong>STDES-67W61BU-U5<\/strong>\u00a0reference design that pairs the ST67W611M1 with an STM32U5. We have already updated STM32CubeMX, and\u00a0<strong>X-CUBE-ST67W61<\/strong>\u00a0software package, which contains drivers, firmware for the STM32U5, STM32H5, STM32H7, and STM32N6, and application examples, also helps reduce development times. Moreover, developers can already use the Wi-Fi module with nearly all STM32 devices. Put simply, this announcement demonstrates why engineers have been seeking a more seamless integration of a Wi-Fi module with the STM32 ecosystem and how the new solution leverages the existing ecosystem that ST has developed over the years.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"whypartnerwithqualcommtechnologiescertifiedhigh-performancewirelessconnectivity\">Why partner with Qualcomm Technologies? Certified high-performance wireless connectivity<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"flexibilityandpragmatism\">Flexibility and pragmatism<\/h3>\n\n\n\n<p>The ST67W611M1 module comes in three variants for greater flexibility. We provide a model with an integrated antenna (ST67W611M1A6B), one with an MHF4 connector for an external antenna (ST67W611M1A6U), and the ST67W611M1A6P, which supports a pinned antenna. All of them are pin-to-pin compatible with each other.&nbsp;<strong>Put simply, we ensure that engineers can easily tailor their BOM should they choose a different model on their journey to their final design.<\/strong>&nbsp;ST is also making the new device pragmatic by ensuring that Wi-Fi and Bluetooth LE come with global certifications (USA, Canada, Europe, UK, Japan, Australia, New Zealand, India, Thailand, and more soon), thus making it far easier for companies to bring their products to market.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"performanceandenergyefficiency\">Performance and energy efficiency<\/h3>\n\n\n\n<p>The new Wi-Fi\/Bluetooth combo uses a 40-nm process node, 4 MB of flash with over-the-air update capabilities, and supports 2.4 GHz 802.11b\/g\/n\/ax, which is the frequency with the greatest reach.&nbsp;<strong>The ST67W611M1 also offers a TCP throughput of up to 18 Mbps, which far exceeds the needs of most IoT applications.<\/strong>&nbsp;It also features a transmit output power of +21 dBm, while providing optimized adjacent channel interference reduction and a deep sleep mode of 90 \u00b5A, along with a wake-up time of between 50 ms and 100 ms.<\/p>\n\n\n\n<p>In essence, the collaboration between Qualcomm Technologies and ST not only guarantees a Wi-Fi module that\u2019s easy to use, but one that respects the energy constraints most IoT solutions face.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ST and Qualcomm Technologies, Inc are thrilled to announce the mass market availability of the\u00a0ST67W611M1, a Wi-Fi co-processor stemming from our strategic collaboration, paving the way for future innovations.\u00a0Compatible with Wi-Fi 6 and Bluetooth 5.4, support for Matter over Wi-Fi should arrive in Q3, while Matter over Thread should come later in the year.
