SX1282 Datasheet | SEMTECH

.. WIRELESS & SENSING PRODUCTS Description Transceiver/MCU/ADC System-on-Chip with RISC CPU for Battery-Powered Ultra-Low Power Applications The SX1282 transceiver with embedded Cool RISC® MCU, dual 10 and 16-bit ADC and peripherals provides a highly-integrated single-chip acquisition processing and RF solution. With a design which sets state-of-the-art standards in low receiver consumption, dual ISM-band transceiver blocks are bined with a sophisticated ultra low-power 8-bit RISC core plus extensive signal acquisition peripherals to provide a plete system on chip for ISM-band applications. The SX1282 is manufactured in an ultra modern 0.18µm process, with the entire radio, Cool RISC MCU, ADCs, peripherals, inductors and filters all integrated on a single die. The circuit is capable of operating down to 1.0V, which makes operation from a single alkaline battery possible. The circuit is enclosed in a 60-pin QFN package of dimensions 7x7mm. Features - Operating voltage down to 1.0V - Supply voltage range from 1.0V to 1.6V - Entire circuit can operate on a single AA battery - Transceiver Chain - Dual-Band operation, 434 MHz and 868 MHz - Multi-channel, on-chip PLL,12.5 k Hz steps - FSK and OOK modulation - Data rate up to 80 kbit/s FSK - Sensitivity of -102 d Bm @ 25 kbit/s, FSK, 10-3 BER - Receive current 2.5 m A - Autonomy up to four years from a single AA battery in wireless sensing - Transmit power +10 d Bm differential (35 m A supply current) - Integrated RX-TX switch - Super heterodyne architecture - First conversion: IF @ 96 MHz for 868 MHz band - Second conversion: zero IF - HW support for symbol synchronization and clock recovery - Power Management - High-current step-up for external EEPROM supply @ 2.7V - Low-current step-up for the supply of the data acquisition chains - POR and brown-out detector - Sophisticated Power Management - Unused blocks...
