AX-SIP-SFEU, AX-SIP-SFEU-API Sigfox RF Transceiver System in Package (SiP) for Up-Link and Down-Link Applications www.onsemi.com UltraLow Power, UltraMiniature, AT Command/API Controlled, Sigfox Verified and CE Certified OVERVIEW Conformal shielding Supply range 2.1 V 3.6 V Circuit Description AXSIPSFEU and AXSIPSFEUAPI are ultralow 30C to 85C power, ultraminiature SysteminPackage (SiP) solutions Temperature sensor for a node on the Sigfox network with both up and Supply voltage measurements downlink functionality. 15 GPIO pins With a footprint of just 7 mm 9 mm and conformal 6 GPIO pins with selectable voltage measure shielding, the AXSIPSFEU SiP, contains all the necessary functionality, differential (1 V or 10 V range) or components and firmware for transmit and receive single ended (1 V range) with 10 bit resolution operation on the European (RC1) Sigfox network. No 2 GPIO pins with selectable sigma delta DAC additional passive components or reference frequency output functionality providing parts are required on the customers PCB. 2 GPIO pins with selectable output clock A singleended 50 antenna port is provided. 3 GPIO pins selectable as SPI master interface The AXSIP SFEU connects to the customer product Integrated RX/TX switching with singleended using a logic level RS232 UART. AT commands are used to 50 antenna pin send frames and configure radio parameters. The AXSIP SFEU API variant is intended for Power Consumption: customers wishing to write their own application software Ultralow Power Consumption: based on the AXSIPSFLIB1GEVK library. Charge required to send a Sigfox OOB packet at The SiP is fully Sigfox Verified and CE certified, vastly nominal transmitter power (13 dBm typical at reducing risk and time to market delays. nominal temperature): 0.24 C Deep Sleep mode current: 180 nA Features Sleep mode current: 1.2 A Functionality and Ecosystem: Standby mode current: 0.55 mA Single package, zero external components, full Sigfox Continuous radio RXmode at 869.525 MHz: uplink and downlink functionality controlled by AT 14 mA commands or API Continuous radio TXmode at 868.130 MHz: The AXSIPSFEU and AXSIPSFEUAPI SiPs are 45 mA nominal transmitter power (13 dBm) part of a whole development and product ecosystem High Performance Narrowband Sigfox RF Transceiver available from ON Semiconductor for any Sigfox Receiver requirement.
