Anaren Integrated Radio (AIR) Low-power RF modules, rfi mware & development tools that make it easy to go wireless 2541 System on Chip Series The A2541R24A is a surface-mount radio module featuring Bluetooth SMART technology that incorporates the Texas Instruments ultra-low-power CC2541 SoC, crystals, a PCB antenna and a DC/DC converter, all in one of the industrys smallest packages: 11x19x2.5mm. The module is pre-loaded with either TIs BLE-Stack or Em-Ware software from Emmoco and is certified with the Bluetooth SIG, US (FCC), Canada (IC), and compliant with European (ETSI) and other global standards. A2541R24A Features Benefits General: Minimal RF engineering experience necessary 2.4-GHz RF transceiver incorporating Minimal Bluetooth experience necessary Bluetooth SMART technology Easy to implement, short design cycle Excellent receiver sensitivity and robustness to No additional Intentional Radiator certification interference (-89/-94dBm typical in BLE LGM/HGM required (FCC 15.247, IC RSS-210, EN 300 328) mode with <0.1% BER) FCC ID: X7J-A12062101 // IC: 8975A-A12062101 Programmable output power up to +1dBm Minimal real estate required Supports data rates up to 2 Mbps Easily implemented on a two layer PCB Wide input voltage range (2.0V 3.6V) No additional harmonic filtering required Available in tape & reel and matrix tray 100% RF-tested in production Module weight approximately 0.7 grams Common footprint for similar products in family Certified/compliant for use in USA, Canada, Europe, No additional DC decoupling required and many other global locations Accurate Digital RSSI support Current Consumption: (Typ TC = 25C, VDD = 3.0V) Operating temperature 40 to +85C Active mode RX (CPU Idle): 14 mA PLEASE NOTE: Active mode TX (CPU Idle): 13 mA 0dBm, with Additional information on the Texas Instruments CC2541 3 low power/sleep modes from 0.5uA to 270 uA device can be found in the companys latest datasheet Features TI TPS62730 step-down converter for release at Anaren Integrated Radio (AIR) Low-power RF modules, rfi mware & development tools that make it easy to go wireless Product overview Block diagram The A2541R24A is a high-performance, FCC & IC certified and ETSI-compliant SOC module featuring Bluetooth SMART technology that incorporates the Texas Instruments CC2541 transceiver chip in one of the industrys smallest package (11 x 19 x 2.5 mm). The module incorporates two crystals, TPS62730 step-down converter and the required RF matching and filtering for regulatory compliance. The modules operate in the global unlicensed 2.4GHz ISM/SRD frequency band. These radio modules are ideal for achieving low power wireless connectivity without having to deal with extensive Protocol, RF design and regulatory compliance, allowing quick time to market. The modules are 100% RF-tested to provide consistent performance.
