Product details
Overview
ATSAMB11-ZR210CA from Microchip Technology is a fully certified Bluetooth Low Energy 5.0 System-in-Package (SiP) module integrating the ATSAMB11-XR2100A SoC, RF front-end, T/R switch, and a ceramic high-gain chip antenna. It delivers -92.5 dBm RX sensitivity, programmable TX output from -55 to +3.5 dBm, and ultra-low power operation (2.03 µA sleep current), enabling compact, battery-powered BLE end nodes such as medical sensors and asset trackers.
For engineers reviewing the ATSAMB11-ZR210CA datasheet, ATSAMB11-ZR210CA pinout, ATSAMB11-ZR210CA application, or ATSAMB11-ZR210CA equivalent, key selection criteria include its pre-certified RF design (QDID 117593), integrated antenna eliminating external matching, 32.768 kHz RTC requirement, and support for Microchip BluSDK Smart with SIG-qualified profiles.
Technical Context
The ATSAMB11-ZR210CA embeds the ATSAMB11-XR2100A die - an ARM Cortex-M0 MCU with 256 KB Flash, 128 KB RAM, and dedicated BLE protocol stack in ROM - within a shielded 35-pin module package. Its RF subsystem includes a fully matched 2.4 GHz transceiver with integrated T/R switch and monolithic ceramic antenna, bypassing discrete RF layout and tuning.
Power management integrates a buck DC/DC converter supporting 2.3–4.3 V battery input, while timing relies on both an internal 26 MHz XO and external 32.768 kHz RTC crystal. The module operates across -40°C to +85°C and supports BLE 5.0 features including LE 2M PHY and extended advertising.

Equivalent & Alternatives
The following parts are listed as comparable options for similar BLE SiP/module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| nRF52833 DK (nRF52833 + PCB antenna) | Requires external antenna matching and full RF layout; no integrated ceramic antenna or pre-certification. | Demands RF validation and regulatory testing; suitable only for designs with in-house RF engineering resources. | Select when custom antenna placement or multi-band support (e.g., Thread/Zigbee) is required beyond BLE-only use. |
| ESP32-WROOM-32 | Wi-Fi + BLE dual-mode; higher sleep current (~10 µA); larger 18 mm × 25.5 mm footprint; no BLE 5.0 QDID. | Introduces Wi-Fi interference risk in dense BLE deployments; less optimal for pure low-power BLE sensor nodes. | Choose only if concurrent Wi-Fi connectivity and cloud uplink are mandatory and power budget permits. |
Compared with nRF52833 DK and ESP32-WROOM-32, ATSAMB11-ZR210CA reduces time-to-certification by 6–9 months and cuts PCB area by >60%, making it optimal for volume production of compact, battery-constrained BLE peripherals where RF simplicity and regulatory assurance are critical.

FAQ
What regulatory certifications does the ATSAMB11-ZR210CA hold?
The ATSAMB11-ZR210CA holds Bluetooth SIG qualification (QDID 117593) for BLE 5.0 interoperability and is pre-certified for FCC Part 15.247, IC RSS-247, and CE RED compliance. These approvals cover conducted and radiated emissions, intentional radiator limits, and RF exposure - allowing direct integration into end products without additional RF testing.
Does the ATSAMB11-ZR210CA require an external crystal oscillator?
Yes, the ATSAMB11-ZR210CA requires a 32.768 kHz crystal connected to XTAL32K pins for real-time clock functionality and low-power sleep/wake timing. The 26 MHz crystal is internal to the ATSAMB11-XR2100A die and not exposed externally - no 26 MHz crystal is needed on the host PCB.
Can the ATSAMB11-ZR210CA operate without the integrated chip antenna?
No - the ATSAMB11-ZR210CA is a fully encapsulated module with a monolithic ceramic chip antenna embedded in the package. There is no ANT pad or RF test point for external antenna connection; the antenna is non-removable and integral to the module's RF certification and performance.
What development tools support firmware development for the ATSAMB11-ZR210CA?
Firmware development for the ATSAMB11-ZR210CA is supported by Microchip's MPLAB X IDE with XC32 compiler, the ATSAMB11-XR2100A Curiosity Development Board (DM320116), and the BluSDK Smart software suite. Debugging uses standard SWDIO/SWCLK pins and is compatible with PICkit™ 4 and Atmel-ICE programmers.
How does the power management architecture of the ATSAMB11-ZR210CA reduce system-level complexity?
The ATSAMB11-ZR210CA integrates a buck DC/DC converter, eliminating the need for external voltage regulation. It accepts 2.3–4.3 V directly from primary batteries and generates stable internal rails, while its 2.03 µA deep-sleep mode and hardware-controlled wake-up timers simplify energy harvesting and battery-life modeling - reducing BOM count and layout area versus discrete PMIC solutions.
