BLE113-A-M256K Visão geral
A Bluetooth Low Energy (BLE) module is a complete wireless subsystem within the broader hierarchy of RF transceiver modules and short-range wireless communication devices. Whereas a bare radio chip requires the designer to integrate a microcontroller, antenna matching network, and protocol stack, a BLE module such as the BLE113 integrates all features required for a Bluetooth smart application: the Bluetooth radio, antenna, MCU, and certified stack, reducing time to market and RF design risk.
Key features include the 256 KB flash variant (versus 128 KB on BLE113-A-V1), which is significant for over-the-air (OTA) firmware updates and extensive BGScript applications, integrated chip antenna eliminating external RF matching design, and low power operation targeted at small sensors and accessories. Serial interfaces include ISP, PWM, SPI, and UART, allowing flexible host connectivity or fully standalone operation via BGSCRIPT.
Technically, the module is built around the Texas Instruments CC2541 utilized IC and belongs to the Bluegiga BLE113 family acquired by Silicon Labs. The -93 dBm sensitivity supports reliable connections at Class 2 power levels on the 2.4 GHz ISM band, and the integrated antenna means the RF performance is pre-certified, saving regulatory test cost.
Typical applications include low-power sensors and accessories, battery-powered health and fitness devices, beacons, smart home endpoints, and industrial wireless sensor nodes where a compact, certified BLE link is required.
A key design consideration is supply voltage: the module accepts only 2.0 V to 3.6 V, so a single CR2032 coin cell or a regulated LiPo rail works well, but 5 V systems require an LDO. Allow antenna keep-out clearance on the PCB around the chip antenna region.

Aplicações típicas
BLE113-A-M256K é adequado para 6 aplicaçãos: Battery-Powered BLE Sensors, Fitness and Health Accessories, Smart Home and IoT Endpoints, iBeacon and Eddystone Beacons, Industrial Wireless Sensor Nodes, Smartphone-Connected Consumer Devices.
Battery-Powered BLE Sensors
The BLE113-A-M256K was purpose-built for small and low power sensors and accessories, making it the default choice for coin-cell sensor nodes. Its 2.0 V to 3.6 V supply accepts a CR2032 directly without a regulator, and Bluetooth Low Energy connection intervals let the module sleep at microamp average current between events. The 256 KB flash leaves room for sensor calibration tables, a full BGScript application, and an OTA update image simultaneously. In a typical temperature or humidity sensor node, the module connects via its SPI, UART, or PWM interfaces to the sensor IC and reports over BLE GATT characteristics at -93 dBm sensitivity, giving reliable whole-home coverage from the integrated chip antenna with zero external RF components.

Fitness and Health Accessories
Wearable health and fitness products such as heart-rate straps, activity trackers, and thermometers benefit directly from the BLE113-A-M256K integration level: radio, MCU, certified Bluetooth 4.0 stack, and chip antenna in one castellated surface-mount module, shrinking the wireless BOM to a single part. The 2 Mbps over-the-air rate handles streaming sensor data to smartphone apps, while the standard GATT profiles used by the Silicon Labs stack ensure interoperability with iOS and Android devices. Because regulatory certification of the radio is already completed at module level, accessory makers avoid costly RF requalification. The 256 KB flash supports OTA firmware updates, a practical necessity for consumer wearables that receive feature updates in the field.

Smart Home and IoT Endpoints
Smart home endpoints such as door/window sensors, smart plugs, lighting controls, and BLE-to-cloud bridges use the BLE113-A-M256K as a certified 2.4 GHz Bluetooth Smart link. The UART and SPI interfaces connect cleanly to any host MCU, or BGScript eliminates the host MCU entirely for simple devices, cutting BOM cost. The -93 dBm receiver sensitivity and integrated chip antenna deliver Class 2 range suitable for room-to-room coverage, and the 2.0 V to 3.6 V supply works from mains-derived 3.3 V rails or backup coin cells for power-loss memory retention. OTA capability enabled by the 256 KB flash lets installed endpoints receive stack and application updates without physical access, which is essential for large smart home fleets.
Recomendado
iBeacon and Eddystone Beacons
Proximity beacons are an ideal single-purpose fit for the BLE113-A-M256K: the device only transmits periodic advertisement packets, so it can run for many months on a CR2032 cell within the module's 2.0 V to 3.6 V input range. A compact BGScript application configures the 256 KB flash to hold multiple beacon frames (iBeacon, Eddystone-URL, Eddystone-UID) and switch between them, while the integrated chip antenna provides consistent radiated output without RF tuning. Deployments in retail proximity marketing, asset tracking, and indoor navigation use the module's configurable advertising interval to trade beacon rate against battery life, and OTA updates allow re-flashing beacon identifiers across a fleet without physical retrieval.

Industrial Wireless Sensor Nodes
Industrial condition-monitoring nodes measuring vibration, current, or temperature use the BLE113-A-M256K to bridge sensor frontends to smartphones and gateways without cabling. The module's SPI and UART interfaces connect to industrial ADCs and MCUs, PWM supports simple actuator or alarm outputs, and the castellated pads allow reflow soldering onto conformal-coated industrial PCBs. The -93 dBm sensitivity penetrates typical factory obstruction better than lower-sensitivity radios at Class 2 power, and operation down to 2.0 V permits direct battery backup designs. With the certified Bluetooth Smart stack on-module, integrators avoid RF layout risk in electrically noisy enclosures, and the 256 KB flash hosts protocol translation firmware alongside OTA maintenance images.

Smartphone-Connected Consumer Devices
Consumer products that pair with a mobile app - toys, locks, scales, coffee machines, audio accessories - use the BLE113-A-M256K as the certified wireless interface. Because the Bluetooth 4.0 stack runs on-module and exposes a simple UART/SPI API, the host MCU only needs to implement product logic, and the CC2541-based radio interoperates with every BLE-capable phone. The 2 Mbps air rate provides responsive app interaction, the chip antenna removes RF certification design work, and the 3.3 V-friendly supply integrates into typical consumer electronics rails. The 256 KB flash supports product-specific GATT services plus OTA update capability, letting manufacturers ship hardware early and refine firmware through app-triggered updates after launch.

Principais diferenciais
- Double the flash for OTA and large BGScript apps (vs BLE113-A-V1)
- Longer-range sibling with same flash (vs BLE121LR-A-M256K)
- Newer generation sensitivity (vs BLE112-A-V1)
Notas de projeto
Design the supply rail for 2.0 V to 3.6 V strictly; 3.3 V LDO output or a fresh lithium coin cell sits comfortably in range. Place a 100 nF ceramic capacitor close to the module supply pads plus bulk 10 uF for TX burst current. Estimated: BLE-class radios draw burst currents in the tens of milliamps during transmit; undersized decoupling causes brownout resets during connection events, so verify rail droop with an oscilloscope on first prototypes.
Respect the antenna keep-out: no copper pours, traces, ground planes, batteries, or metal enclosures in the region specified by the Silicon Labs datasheet around the integrated chip antenna end of the module. Even though the antenna is pre-tuned and certified, nearby dielectric or metal detunes it and can cost several dB of link margin. If the enclosure is metal, place the module at a plastic window or use an external antenna variant instead.
Confirm flash budget early: the -M256K was chosen over BLE113-A-V1 specifically for OTA updates or large BGScript applications, which consume the 256 KB quickly. If you later footprint-swap to BLE113-A-V1 (128 KB), OTA images plus application may no longer fit. Also note that BLE113-A-M256K-MT4 is a custom preloaded-firmware OPN available only direct from Silicon Labs - do not expect to source it from distribution.
