UM2080F32 — 32-bit Sub-1GHz Wireless SoC

The UM2080F32 is an ultra-low-power, high-performance 32-bit SoC built around an ARM Cortex-M0+ core with a fully integrated (G)FSK/OOK transceiver operating in the 200–960 MHz range. It supports flexible packet formats, auto-ACK/retransmit, frequency hopping, and FEC. The chip contains a complete RF receiver, transmitter, frequency synthesizer, and modem — requiring only simple, low-cost external components for excellent RF performance.

The UM2080F32 also integrates CAN, 12-bit SAR ADC, UART, SPI, QSPI, I²C, OPA, comparators, LPTIMER, WDT, and built-in RC oscillators. Its unique low-power design delivers high integration, strong anti-interference capability, high reliability, and ultra-low power consumption. Development is supported in Keil MDK with C and assembly languages.
