What Last Mile Semiconductor does

Last Mile Semiconductor GmbH is a fabless semiconductor startup headquartered in Dresden, Germany, within the Silicon Saxony microelectronics cluster. Founded in 2024, the company designs and markets the LM10xx System on Chip, a single-chip solution based on the NR+ (DECT NR+) standard — a globally license-free, non-cellular 5G technology operating in the 1.9 GHz DECT spectrum. The LM10xx integrates a dual-core 200 MHz RISC-V application processor, up to 3 MB NVM and 512 KB RAM, an integrated 1.9 GHz low-power NR+ radio, a quantum-proof hardware secure element (secure boot, secure firmware update, ECDSA, X.509, tamper detectors, side-channel leakage protection), and comprehensive peripherals including a 14-bit ADC. The chip is built on 22nm FDSOI technology and supports up to 6 km range, up to 10 Mbit/s data rate, and sub-millisecond latency in both star and mesh topologies. The product is targeted at professional IoT device manufacturers across four primary use-case segments: Industrial IoT, Smart Energy, Smart Building, and Smart City.

Last Mile Semiconductor monetizes the LM10xx SoC via direct hardware sales to OEMs, with a Zephyr RTOS-based SDK supporting Matter, DLMS/COSEM, and Profinet protocols over IPv6 to accelerate integration. Pricing is not publicly disclosed and is likely negotiated per volume/order. The company's go-to-market relies on enterprise field sales triggered by datasheet and SDK information requests on its website, content marketing through its corporate blog, and participation in standards-aligned industry events such as CSA Unify. The firm is embedded in the NR+ partner ecosystem alongside Nordic Semiconductor, Wirepas, Siemens, Schneider Electric, Legrand, DSR, the DECT Forum, and CSA, and has secured non-dilutive capital from the European Union via the SEMECO-B4 project and EIC Accelerator, supplemented by regional Saxon investors. Customer logos and revenue figures are not publicly disclosed.

Broad incumbents

• Infineon Technologies: Infineon is a broad semiconductor incumbent with AIROC Wi-Fi/Bluetooth and PSoC/industrial MCUs serving smart building, smart energy, and industrial automation — directly adjacent to LMS's Industrial IoT, Smart Energy, and Smart Building segments. Infineon's focus on security and European regulatory compliance mirrors LMS's positioning.
• Texas Instruments: TI's CC13xx/CC26xx SimpleLink wireless MCUs serve the same industrial IoT, building automation, and asset-tracking markets with sub-GHz and 2.4 GHz connectivity. As a broad incumbent with massive scale, TI competes on BOM cost, longevity, and developer ecosystem rather than on a focused NR+ proposition.
• STMicroelectronics: STM32 wireless MCUs (including STM32WL sub-GHz LoRa SoCs) and Bluetooth/Thread/Matter solutions serve overlapping industrial and smart-metering markets. Like LMS, STM emphasizes integrated security and European manufacturing footprint, making it a credible alternative for industrial buyers.
• Renesas Electronics: Renesas offers RA, RX, and RL78 MCU families plus wireless connectivity (DA16xxx, Bluetooth/Thread SoCs) for smart building, metering, and industrial IoT. Comparable in target verticals and integrated security approach, with significantly broader scale.
• NXP Semiconductors: NXP's Kinetis, i.MX RT, and wireless connectivity solutions target industrial IoT and smart-building markets. Overlaps with LMS on smart-metering/utility and building-automation customers, with comparable emphasis on hardware-rooted security and regulatory compliance.

Emerging players

• Espressif Systems: Espressif's ESP32 series provides highly integrated Wi-Fi/Bluetooth SoCs at low cost for IoT, with a strong developer ecosystem. While protocol-overlap is partial (no NR+), Espressif competes for the same low-power, integrated-radio, secure-IoT design slots that LMS targets.
• Qorvo: Qorvo's ultra-wideband, sub-GHz, and IoT connectivity solutions (including DECT-related RF front-ends) serve industrial IoT and smart infrastructure markets. Partial overlap in RF/connectivity for smart-building and asset-tracking applications where LMS targets.
• Wirepas: Wirepas provides mesh networking software for IoT (including over NR+/DECT) and is a listed LMS ecosystem partner. Although more software/partner than direct chip competitor, Wirepas-enabled competing hardware (e.g., Nordic-based radios) is a substitute LMS design-in risk in industrial mesh deployments.

Direct peers

• Silicon Labs: Silicon Labs ships integrated wireless SoCs (Series 2) targeting smart home, industrial, and smart-metering applications. Overlaps with LMS on target verticals, integrated MCU + secure-element + multi-protocol approach, and enterprise field-sales motion to OEMs.
• Nordic Semiconductor: Nordic is the most direct peer — a fabless wireless SoC leader that also develops DECT NR+ silicon and is part of the same NR+ ecosystem alongside Last Mile Semiconductor. Both target low-power IoT connectivity with integrated MCU + radio architectures, making Nordic the primary head-to-head competitor.
