New Product Introduction

ON Semiconductor AX8052F143 ultra-low RF microcontroller

The AX8052F143 is a one chip solution compatible with many standard applications in the IoT.


The AX8052F143 is a one chip solution compatible with many standard applications in the IoT. A sensitivity of -126 dBm at 868 MHz and 1.2 kbps with a current consumption of only 9.5 mA make the AX8052F143 an outstanding device in its field.
The low phase noise and high efficiency 16 dBm transmitter are obvious features. Data-rates range from 0.1 to 125 kbps. The frequency range from 27 MHz to 1050 MHz allows this RF-microcontroller to be the ideal device for many applications including automatic meter reading and security. The average 4.5 µA duty-cycle recieve current is just one of the many outstanding parameters.
The AX8052F143 microcontroller core executes the industry standard 8052 instruction set. The system clock can be programmed freely from DC to 20 MHz. As instructions are executed in a single cycle, the core can deliver 20 MIPS. A 64 kByte flash memory is provided, allowing to program applications in C. A fully associative cache and a pre-fetch controller hide the latency of the flash memory.
The AX8052F143 features a dual channel DMA engine that can transfer data to and from XRAM to any peripheral on chip. A dedicated AES engine with its own DMA engine is provided for encryption.Further peripherals include three general purpose timers with optional sigma-delta output mode. The timers can be used as baud rate generators for the two UARTs. A master/slave SPI interface is provided. A 10-bit, 500 kSample/s ADC with flexible input modes, as well as comparators allow to interface with analog data streams.
The F143-Mini-DVK is a miniaturized development kit for the designer starting out with the AX8052F143 ultra-low power high performance SoC RF-Microcontroller. The F143-Mini-DVK hardware consists of a USB debug adapter and a pair of RF modules (F143-Mini-A-MOD and F143-Mini-B-MOD modules) and includes all software necessary to develop systems in shortest times. The modules have a tiny footprint of just 33 x 15 mm2. One module comes with a chip antenna the other is equipped with an SMA connector.
