4 / 35 page  Silicon Labs BLE121LR Bluetooth® Low Energy Module DESCRIPTION BLE121LR is a Bluetooth Low Energy Long Range module targeted for Bluetooth Low Energy applications where the best possible RF performance and range are required. At +8 dBm TX power and -98 dBm sensitivity BLE121LR has best-in-class RF performance and can provide Bluetooth Low Energy connectivity up to 450 meters. BLE121LR integrates all features required for a Bluetooth Low Energy application: Bluetooth radio, software stack and GATT based profiles. and it can also host end user applications, which means no external micro controller is required in size, price or power constrained devices. BLE121LR Bluetooth Low Energy module also has flexible hardware interfaces to connect to different peripherals or sensors. Although BLE121LR Bluetooth Low Energy Long Range Module is target for applications requiring high RF performance, it is still has relatively low power consumption and can be power using a standard 3V coin cell batteries. APPLICATIONS: • Smart home accessories • beacon devices • Health and fitness sensors • Medical sensors • iPhone and iPad accessories • Security and proximity tags KEY FEATURES: • Bluetooth v. 4.0 Single Mode Compliant o Master and slave modes o Up to eight connections • Integrated Bluetooth Low Energy Stack o GAP, ATT and GATT o Bluetooth Low Energy profiles • Best-in-Class RF Performance o Transmit power : +8 dBm o Receiver sensitivity: -98 dBm o Range up to 450 meters • Low Current Consumption o Transmit: 36 mA (+8 dBm) o Receive: 33 mA (-98 dBm) o Power mode 3: 0.5 uA • Flexible Peripheral Interfaces o UART and SPI o I2C, PWM and GPIO o 12-bit ADC • Host Interfaces: o UART • Programmable 8051 Processor for Stand-alone Operation o Simple Bluegiga BGScriptTM scripting language for quick application development o Bluegiga Profile ToolkitTM allowing the quick development of GATT based profiles • Dimensions: 14.7 x 13.0 x 1.8 mm • Bluetooth, CE, FCC, IC, South Korea, Japan and Brazil qualified |
