ON Semiconductor’s AX8052F143 is an RF microcontroller offering high performance combined with low power consumption over a broad frequency range of 27MHz to 1,050MHz.

By combining a microcontroller core with an RF transceiver in a single chip, the AX8052F143 enables designers to save board space, design time and bill-of-materials costs compared to circuits comprised of a discrete MCU and RF ICs.

ON Semiconductor provides a development ecosystem to support the AX8052F1xx family of devices, including a C compiler, Integrated Development Environment (IDE) and application generator. In addition, ON Semiconductor can pre-programme AX8052F143 devices to implement standard protocols such as SIGFOX, EnOcean, KNX or Wireless M-Bus.

The AX8052F143 is notable for its low power consumption. At its maximum RF power output of 16dBm at 868MHz, the transmitter draws just 48mA. In addition, the receiver’s high sensitivity – up to -137dBm at a low data rate – enables the AX8052F143 to be used in applications requiring a high link budget.

Spans of more than 15km are possible without the need for an external RF power amplifier or low-noise amplifier.

A dedicated AES engine is provided for encryption. For wireless communication at frequencies up to 1,050MHz,
ON Semiconductor also supplies:

  • the AX5051, a universal wideband single-chip RF transceiver supporting the 433MHz, 868MHz and 915MHz Short-Range Device (SRD) frequency bands
  • the AX5043 narrowband, ultra low-power RF transceiver operating at frequencies between 27MHz and 1,050MHz. It supports the FSK, MSK, 4-FSK, GFSK, GMSK, AFSK and ASK modulation schemes. Unlike the AX8052F143, it does not include a built-in MCU core.
