AX8052F143 - Ultra Low Power RF Microcontroller IC

System-on-Chip ultra-low-power RF Microcontroller IC for the 70 - 1050MHz bands

The RF-microcontroller AX8052F143 can output 0 dBm with the record breaking low current consumption of 8 mA at 1.8 V or 5 mA at 3.6 V supply voltage in the 868 MHz or 926 MHz frequency ranges. Combined with its 10 mA current consumption in receive mode the AX8052F143 is enabling technology for battery driven or energy harvesting based wireless Internet of Things (IoT) or Machine to Machine (M2M) nodes.

High performance narrow-band wireless RF solution

The AX8052F143 targets the highest performance narrow-band market with demands for many miles of communication range. A sensitivity of -126 dBm (-129 dBm with FEC) at 868 MHz and 1.2 kbps with a current consumption of only 12.5 mA (RF and MCU both running) 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 1 to 115.2 kbps. The frequency range from 70 MHz to 1050 MHz allows this RF-microcontroller to be the ideal device for many applications including automatic meter reading and security. The average 6 µA duty-cycle receive current is one of the many outstanding parameters.

AX8052 microcontroller core

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.
AX8052F143 specifically targets ultra-low power applications. Four system clock sources can be selected on the fly, allowing to flexibly adapt the system speed to varying application needs. The core consumes 150 µA/MHz and AX8052F143 consumes 950 nA in sleep mode with wake-up timer running and with 256 Byte SRAM retention.

Powerful peripherals tailored to support SRD applications

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.

Productivity enhancing complete development tool suite

A hardware debug unit considerably eases debugging compared to other 8052 microcontrollers. The debug unit communicates with a host PC running the debugger using a 3-wire interface. AX8052F143 is supported by the AXSEM development kit DVK-2. This is a complete and flexible ready-to-go solution for easy testing, evaluation and development with RF ICs. It is suited for real performance tests using professional lab equipment, as well as for application code development.
