ATSAMB11-XR2100AT Visão geral
What is a BLE SiP module? A System-in-Package (SiP) module is a miniaturized electronic assembly that combines multiple ICs - here a microcontroller, radio transceiver, power management, and passive RF components - inside one substrate-level package. Compared to a discrete MCU plus transceiver design, a BLE SiP shortens RF design time, eliminates bill-of-material duplication, and minimizes the PCB footprint required to add Bluetooth Low Energy to an embedded product. Within the wireless module hierarchy, ATSAMB11 sits between bare SoCs (which require external balun, antenna matching, and crystal) and pre-certified modules (which add the regulatory certification layer).
Key specifications of the ATSAMB11-XR2100AT include an integrated Cortex-M0 core with embedded Flash memory, support for BLE v4.2 protocol features, and ultra-low-power operating modes targeted at battery-powered IoT endpoints. The module's PMU handles DC-DC conversion internally, freeing the host board from complex power-tree design. Its surface-mount LFLGA-49 footprint is suitable for reflow soldering on standard FR-4 PCBs.
Architecturally, the SiP pairs an ATSAM D-series-class Cortex-M0 microcontroller die with Microchip's BLE radio die, interconnected via an internal serial bus. This co-design allows the firmware to control radio events, sleep cycles, and advertising intervals directly from the application code, eliminating the external host-processor burden common to discrete BLE chipsets.
Typical applications include IoT sensor nodes, smart-home lighting controls, fitness bands, BLE beacons for asset tracking, and wireless human-interface devices (HID) such as remote controls and smart styluses. The integrated antenna and pre-tuned RF matching simplify Type 1 antenna designs.
Design consideration: because this is a SiP module rather than a bare IC, layout should treat the module as a single RF component - keep the keep-out area beneath the antenna trace clear of copper, route the host MCU I/O away from the RF section, and follow the reference PCB stackup in the manufacturer's datasheet for antenna-matching reproducibility.

Aplicações típicas
ATSAMB11-XR2100AT é adequado para 6 aplicaçãos: IoT Sensor Nodes, Smart Home Lighting Controls, Fitness Bands and Wearables, BLE Beacons for Asset Tracking, Wireless HID Remotes and Styluses, Industrial Wireless Sensor Modules.
IoT Sensor Nodes
The ATSAMB11-XR2100AT is well-suited to battery-powered IoT sensor endpoints thanks to its integrated Cortex-M0 core, BLE v4.2 radio, and on-chip PMU. Its deep-sleep current and advertising-only mode support multi-year coin-cell operation for temperature, humidity, or motion sensors. Placing the module at the PCB edge with a clear antenna keep-out zone preserves radiated efficiency, while the external wire antenna allows enclosure-tuned matching for retrofit industrial housings.
Recomendado
Smart Home Lighting Controls
BLE-based lighting remotes and dimmers benefit from the ATSAMB11-XR2100AT's sub-1-second wake-and-advertise cycle, which minimizes perceived latency when a user twists a dimmer knob. The integrated Cortex-M0 runs the lighting control state machine while the BLE stack handles mesh-ready phone pairing. Unlike Wi-Fi modules, BLE avoids 2.4 GHz congestion during high-density installations of dozens of bulbs in one room.
Recomendado
Fitness Bands and Wearables
Wearable fitness bands demand both low average power and a small PCB footprint - both delivered by the ATSAMB11-XR2100AT's integrated BLE v4.2 SiP. The module's 2.4 GHz radio coexists cleanly with Wi-Fi access points in home gyms, while the Cortex-M0 supports on-device step counting or heart-rate fusion before transmitting. The external wire antenna allows the OEM to tune radiation patterns along the wrist band, improving body-loss performance.
Recomendado
BLE Beacons for Asset Tracking
For retail, warehouse, or hospital asset-tracking beacons, the ATSAMB11-XR2100AT provides BLE v4.2 advertising with configurable intervals from 100 ms to several seconds, allowing a trade-off between location freshness and battery life. Its integrated PMU handles the high-peak transmit currents directly from a coin cell, and the LFLGA-49 module footprint drops into compact tag PCBs. The Cortex-M0 can run custom payload formats beyond the standard iBeacon or Eddystone frames.
Recomendado
Wireless HID Remotes and Styluses
BLE-connected remote controls, presentation clickers, and active styluses leverage the ATSAMB11-XR2100AT's sub-15 ms connection interval for a responsive user experience. The Cortex-M0 processes button events or stylus pressure locally and emits HID-over-GATT reports with minimal latency. Compared to proprietary 2.4 GHz protocols, BLE pairs natively with tablets and laptops without additional dongles, reducing end-user friction.
Recomendado
Industrial Wireless Sensor Modules
Industrial sensor modules for predictive maintenance, tank-level monitoring, or HVAC control use the ATSAMB11-XR2100AT to deliver BLE telemetry to a gateway within a 30-50 m line-of-sight range. The SiP integration simplifies IEC 61000-4 EMI compliance because the radio is pre-tuned inside a controlled module boundary. The wire antenna supports metal-enclosure deployments where a chip antenna would otherwise be detuned by nearby conductive surfaces.

Notas de projeto
Treat the ATSAMB11-XR2100AT as an RF component when laying out the host PCB. The LFLGA-49 module requires a copper keep-out region beneath the antenna feed pad and routing traces - the exact dimensions are given in the manufacturer's reference PCB layout. Place the module at the board edge whenever possible to maximize antenna radiation efficiency, and avoid routing GPIO or DC traces beneath the module body.
The integrated PMU handles DC-DC conversion internally, but the host board must still provide a low-impedance supply rail. Decouple the module supply pin with a 1 µF X7R ceramic capacitor placed within 2 mm of the pad, plus a 10 µF bulk capacitor. Peak transmit currents can momentarily reach tens of milliamps, so a regulator with low output impedance during load transients is required.
A common pitfall is reusing the same BLE firmware binary across the ATSAMB11-XR2100AT (wire antenna) and ATSAMB11-XR2100A (chip antenna) variants without retuning the antenna-matching network. Although the silicon is identical, the antenna impedance differs, which can degrade radiated output by 2-4 dB and cause radiated emissions re-certification failures.
