Description

The SX1282 transceiver with embedded CoolRISC?MCU, dual 10 and 16-bit ADC and peripherals provides a highly-in tegrated 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 combined with a sophisticated ultra low-power 8-bit RISC core plus extensive signal acquisition peripherals to provide a complete system on chip for ISM-band applications.
