ATSAMB11-MR510CA 概述
Key features include Bluetooth v4.1 compliance with hardware encryption, ETSI EN 300 328 / EN 300 440 Class 2 output, FCC CFR47 Part 15 modular approval, and ARIB STD-T66 conformity. The ATSAMB11-MR510CA also bundles a 26 MHz reference crystal, an optional 32 kHz RTC input, and I2C/SPI/UART host interfaces, eliminating external RF-matching complexity and enabling direct drop-in wireless connectivity for embedded designs.
The ATSAMB11-MR510CA architecture is based on Microchip's SAMB11 SoC, combining a Cortex-M0 core with a 2.4 GHz radio block. Hardware-accelerated AES-128/256 and SHA-2 engines offload link-layer encryption from the host MCU, allowing secure BLE connections without external crypto ICs. The integrated PMU supports 2.3V to 3.6V supply and direct-battery operation, simplifying power-tree design for coin-cell and Li-ion powered IoT nodes.
Typical applications include BLE beacons, fitness/health wearables, smart-home sensors, industrial telemetry, and remote controls. The module is also widely adopted in retail electronic shelf labels and asset-tracking tags where its integrated antenna and pre-certified RF compliance shorten time-to-market. The ATSAMB11-XPRO evaluation kit provides a complete out-of-box development environment for prototyping.
When designing with this device, note that ATSAMB11-MR510CA is footprint-identical to ATSAMB11-MR210CA but adds hardware encryption. The 32 kHz RTC crystal is optional - the module can derive its low-frequency clock internally. Ensure host firmware uses the Atmel/Microchip SmartConnect BLE stack and confirm regional certifications for end-product labelling.

典型应用
ATSAMB11-MR510CA 适用于 6 应用s: BLE Beacons and Proximity Tags, Wearable Fitness and Health Devices, Smart Home and IoT Sensors, Industrial Wireless Telemetry, Electronic Shelf Labels (ESL), BLE Remote Controls and HID Devices.
BLE Beacons and Proximity Tags
The ATSAMB11-MR510CA is well suited for iBeacon/Eddystone beacon designs requiring long battery life. Its integrated ARM Cortex-M0 core plus BLE 4.1 radio and -96 dBm sensitivity allow coin-cell-powered proximity tags to broadcast for 1-3 years on a single CR2032 cell. The module's pre-certified modular approval eliminates RF compliance testing, accelerating retail and asset-tracking rollouts. Designers can keep the BOM minimal: the module integrates the antenna, 26 MHz crystal, and PMU, so only a battery holder, decoupling capacitor, and host MCU (or the on-board Cortex-M0 itself) are required. The 256 KB flash comfortably stores beacon profiles, custom payload formats, and over-the-air firmware update handlers, while the hardware AES/SHA-2 block secures signed firmware images against tampering in commercial deployments.
推荐
Wearable Fitness and Health Devices
Fitness bands and wearable health monitors benefit from the ATSAMB11-MR510CA's ultra-low-power Cortex-M0 core and BLE 4.1 radio. The integrated PMU accepts 2.3-3.6 V direct from a Li-ion cell, removing the need for an external LDO and reducing quiescent losses. With 4 dBm TX power and -96 dBm RX sensitivity, reliable links to a paired smartphone are maintained even when the wearable is on a wrist behind clothing. The 256 KB integrated flash stores sensor fusion algorithms, activity logs, and BLE GATT profiles, while hardware AES-128/256 encryption protects personal health data (PHI) in transit - a hard requirement for medical-grade devices under FDA and EU MDR guidelines. The compact surface-mount module footprint supports slim wearable enclosures where PCB real estate is at a premium.
推荐
Smart Home and IoT Sensors
Smart-home temperature, occupancy, and air-quality sensors gain a complete wireless front-end from the ATSAMB11-MR510CA. The integrated ceramic chip antenna plus pre-certified RF compliance (FCC Part 15, ETSI EN 300 328, ARIB STD-T66) means designers can ship globally without re-running compliance tests on the radio portion. The module's I2C/SPI/UART host interfaces connect directly to common sensors like the BME280 (environmental) or PIR motion detectors, while the on-board Cortex-M0 runs the BLE stack and sensor sampling logic. Hardware AES-128 encryption from the MR510CA variant secures over-the-air firmware updates, critical for IoT devices deployed in the field for 5-10 years and vulnerable to evolving cybersecurity threats.
推荐
Industrial Wireless Telemetry
Factory-floor wireless sensor nodes use the ATSAMB11-MR510CA for cable-free monitoring of vibration, temperature, and pressure on rotating or remote equipment. The module's surface-mount design and pre-certified 2.4 GHz radio eliminate the need for an external RF matching network, simplifying harsh-environment PCB layout. Although operating temperature is datasheet-dependent, the integrated PMU supports 2.3-3.6 V direct battery or 24 V industrial bus operation with an external regulator. BLE 4.1's adaptive frequency hopping and the module's -96 dBm sensitivity provide robust links in noisy industrial RF environments with Wi-Fi and microwave interference. Hardware AES-256 from the MR510CA variant encrypts proprietary process data in transit, addressing rising IIoT cybersecurity requirements.
推荐
Electronic Shelf Labels (ESL)
Retail electronic shelf labels deploy the ATSAMB11-MR510CA in their thousands per store for wireless price updates. The module's integrated antenna and PMU keep each ESL node's BOM under $1 of components beyond the e-paper display and battery, while 4 dBm TX power covers typical retail floor distances of 15-30 m. BLE 4.1 adaptive frequency hopping is critical in dense retail deployments where hundreds of labels contend with Wi-Fi access points and shopper smartphones. The 256 KB flash stores multi-language price databases and update scheduling logic, while hardware AES encryption protects promotional pricing data from unauthorized competitors sniffing the RF channel - a growing concern in retail loss-prevention strategies.
推荐
BLE Remote Controls and HID Devices
Smart-TV remotes, presentation clickers, and BLE HID input devices use the ATSAMB11-MR510CA for low-latency wireless control. The Cortex-M0 core handles HID report generation and button debouncing, while BLE 4.1's connection subrating (down to 7.5 ms) keeps input lag imperceptible. The module's ultra-low deep-sleep current (sub-microamp when properly configured) extends remote battery life to multiple years on two AAA cells - a key consumer-experience metric. Hardware AES-128 secure connections protect against 'replay' attacks where attackers spoof legitimate remote commands, a vulnerability demonstrated against unencrypted BLE remotes in academic research. The integrated ceramic antenna eliminates the need for a trace antenna, simplifying FCC certification of the final remote-control enclosure.

设计说明
Maintain a minimum 5 mm copper keep-out zone beneath and around the integrated ceramic chip antenna. Ground planes, traces, and components placed too close to the antenna will detune the 2.4 GHz radiator and degrade both TX power and RX sensitivity. The manufacturer's reference layout in the Atmel-42498 datasheet shows the recommended placement on the corner of the PCB with antenna facing outward. Do not place a ground plane on any layer under the antenna zone; if multilayer stack-up requires inner planes, use a cutout.
Place a 10 uF X5R/X7R ceramic bypass capacitor as close as possible to the module's VDD pin, with a parallel 0.1 uF capacitor for high-frequency decoupling. The integrated PMU is sensitive to supply ripple above 50 mV peak - this is especially important when sharing a rail with an external MCU or switching regulator. Estimated: at peak TX current of ~15 mA and 3.3 V supply, voltage drop across a 100 mOhm trace exceeds 1.5 mV per cm, justifying short, wide power traces from the decoupling cap to the module pin.
Do not assume the optional 32 kHz RTC crystal is mandatory - the module can derive its low-frequency clock from the internal 26 MHz oscillator divided down, saving BOM cost at the price of slightly higher sleep current. Verify the SmartConnect BLE stack version supports your required GATT profiles (e.g. standard Battery Service, custom vendors) before committing to firmware. Also note that ATSAMB11-MR510CA and ATSAMB11-MR210CA share a single datasheet (Atmel-42498) - do not interpret the shared document as a typo; both variants are active products.
