BM71BLES1FC2-0004AA 概要
A Bluetooth Low Energy (BLE) module is a type of short-range RF module that integrates a Bluetooth radio, baseband controller, and protocol stack into a single shielded unit. Within the wireless hierarchy, it sits between discrete RF transceiver chips and fully qualified end products, allowing OEMs to skip costly Bluetooth SIG qualification and RF tuning. BLE, also called Bluetooth Smart, is the low-power variant of the Bluetooth 802.15.1 standard optimized for battery-powered devices.
Key features of the BM71 family include Bluetooth 5.0 compliance delivering up to 2.5x throughput improvement over Bluetooth 4.1 based designs, more secure connections, an on-board chip antenna requiring no external RF matching, and full shielding for coexistence with other radios. The embedded firmware implements the complete BLE stack, so the host MCU only needs a simple UART interface.
Technically, the BM71 uses Microchip's certified radio with an embedded protocol stack, offloading advertising, connection management, GATT services, and security pairing from the host processor. Configuration is performed via simple ASCII or transparent UART commands, reducing firmware complexity and certification burden.
Typical applications include IoT sensor nodes, smart home devices, battery-powered beacons, industrial wireless sensors, and connected medical accessories, where the module's low power sleep modes and small 9 x 11.5 mm footprint fit space- and energy-constrained designs.
Design consideration: keep the module antenna region clear of ground planes and metal per Microchip's layout guidelines, and power the module from a clean 3.3V rail with local decoupling.

主な用途
BM71BLES1FC2-0004AA の用途: 6 件s: IoT Sensor Nodes, Smart Home Devices, Bluetooth Beacons and Proximity Tags, Industrial Wireless Sensing, Connected Medical Accessories, Mobile Phone Companion Peripherals.
IoT Sensor Nodes
The BM71BLES1FC2-0004AA fits battery-powered IoT sensor nodes because it combines approximately 1.5 uA sleep current with Bluetooth 5.0 throughput up to 2.5x higher than Bluetooth 4.1 based designs, allowing fast burst transmissions between long sleep intervals. The module hosts the entire BLE stack, so a low-cost 8-bit or entry 32-bit host MCU handles only sensing logic and UART messaging, cutting firmware cost. Its 9 x 11.5 mm shielded footprint with integrated chip antenna slips into small sensor housings without RF layout expertise. Powered from a CR2032 or AAA cell through a 3.3V LDO, a node can advertise for years; the key trade-off is keeping connection intervals long and payload sizes small to stay in the sleep-dominated duty cycle.
おすすめ
Smart Home Devices
In smart home products such as door locks, dimmers, and presence sensors, the BM71BLES1FC2-0004AA provides BLE 5.0 connectivity with more secure connections than Bluetooth 4.1 based predecessors, supporting modern pairing methods required by consumer mobile apps. The shielded module construction limits RF interference with nearby Wi-Fi and Zigbee radios common in smart home hubs, while the integrated chip antenna avoids external antenna BOM cost. Its UART command interface lets a single appliance MCU manage both product logic and BLE provisioning, and Bluetooth SIG qualification transfer through Microchip shortens time to market. The design consideration is enclosure material: plastic housings preserve the omni-directional chip antenna pattern, while metal enclosures require an external antenna zone.
おすすめ
Bluetooth Beacons and Proximity Tags
For iBeacon/Eddystone-style beacons and asset tags, the BM71BLES1FC2-0004AA is attractive because advertising-only operation keeps average current near the module's ~1.5 uA sleep floor, enabling coin-cell lifetimes of one to two years. The 2.5x Bluetooth 5.0 throughput advantage over Bluetooth 4.1 designs matters less for beacons, but BLE 5.0 extended advertising and improved security future-proof the design. The shielded 9 x 11.5 x 2.1 mm package tolerates potting and tight enclosures used in ruggedized tags, and the industrial -40C to +85C rating covers cold-chain and outdoor asset tracking. Configurable I/O per the DS60001372J data sheet allows a button or LED to be driven directly from module pins, eliminating the host MCU in the simplest tags.
おすすめ
Industrial Wireless Sensing
Industrial deployments favor the BM71BLES1FC2-0004AA for its -40C to +85C operating range and shielded construction, which maintain BLE link integrity near motors, VFDs, and other interference sources found on factory floors. Condition-monitoring nodes for vibration, temperature, and current can transmit measurement bursts over BLE 5.0 with up to 2.5x the throughput of Bluetooth 4.1 based modules, shortening radio-on time and battery draw. Because the module carries Microchip's Bluetooth qualification, OEMs avoid per-product SIG certification for industrial SKUs. The 16-SMD footprint supports standard reflow assembly alongside the plant's other PCBs. Layout discipline is critical: keep the antenna clear of grounded enclosures and route the UART host bus away from switching regulator nodes to protect link margin.
おすすめ
Connected Medical Accessories
Consumer and accessory-class medical devices such as glucose meters, pulse oximeters, and medication adherence tags benefit from the BM71BLES1FC2-0004AA's pre-qualified BLE 5.0 link to smartphones via standard GATT profiles, simplifying app integration. The shielded module reduces radiated emissions relevant to EMC testing, and the configurable I/O assignment documented in the BM70/71 User's Guide (DS50002542) lets designers adapt pin functions to the host instrument rather than redesigning the RF section. Active-mode current of roughly 10 mA suits periodic measurement sync sessions from primary cells. Trade-off: this is a connectivity module, not a medical-grade part with special biocompatibility claims, so system-level risk management under the applicable medical quality framework remains the OEM's responsibility.
おすすめ
Mobile Phone Companion Peripherals
Accessories that pair with smartphones - remote controls, bike sensors, smart badges - use the BM71BLES1FC2-0004AA because BLE 5.0 ensures compatibility with current iOS and Android stacks while its improved security supports encrypted pairing required by consumer apps. The module's UART transparent mode lets the accessory's main MCU send application data as if over a serial cable, dramatically shortening firmware development. Its 9 x 11.5 mm chip-antenna footprint fits slim wearable and handheld enclosures, and the 2.5x throughput gain over Bluetooth 4.1 based designs supports faster OTA firmware updates of the host product. Designers should budget active current near 10 mA for sustained transfers and consider a rechargeable Li-Po cell with a low-Iq LDO for form-factor-critical products.

設計ノート
Keep the region around the integrated chip antenna free of ground pour, traces, and metal hardware. Follow Microchip's module layout guidelines in data sheet DS60001372J: typically a clearance keep-out around the antenna end of the module and no ground plane directly beneath the antenna area. Plastic enclosures are preferred; if metal is unavoidable, position the antenna outside the metal volume. Violating antenna keep-outs is the single most common cause of reduced BLE range in BM71 designs.
Power the BM71BLES1FC2-0004AA from a clean 3.3V rail with at least a 10 uF bulk capacitor and a 0.1 uF ceramic placed close to the module supply pin. BLE transmit bursts create current spikes of tens of milliamps; a weak or high-impedance supply causes brownouts and advertising dropouts. If the design sleeps at the module's ~1.5 uA floor, ensure the upstream LDO has an Iq low enough not to dominate the system budget, and avoid linear regulators with high ground-pin current.
Route the UART host interface as short, direct traces with a common ground reference to the host MCU. Because the BM71 handles the full BLE stack, the host link is the main noise entry point - keep it away from switching-regulator inductors and high-dv/dt nodes. Per DS60001372J, the I/O pin assignment is configurable; finalize the pin map against your firmware build before layout freeze, and add series resistors on UART lines if long board spans or cable connections are involved.
