RF Microcontrollers

The AX8052F1xx family combines the superb performance of ON Semiconductor’s wireless transceiver technology with an ultra-low-power microcontroller featuring 64 kB Flash, 9.25 kB RAM, and sleep current consumption of 500 nA to 1500 nA. The AX8052F100 core is specifically designed to enable one-chip radio solutions for all levels of complexity. Its low power consumption combined with the rich feature set make it the ultimate choice for many RF systems. The AX8052F143 offers the same leading edge performance as the AX5043 combined with the flexibility and features of a leading edge 8-bit microcontroller on a single SoC without any sacrifice of performance.
