Description
SX1282
Transceiver/MCU/ADC System-on-Chip with RISC CPU
for Battery-Powered Ultra-Low Power Applications
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.
The SX1282 is manufactured in an ultra modern 0.18µm
process, with the entire radio, CoolRISC MCU, ADCs, pe-
ripherals, 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.
