Description

Universal short range wireless RF solution

The AX8052F151 is a complete universal RF-microcontroller for usage in the 400 - 470 MHz and 800 - 940 MHz bands. It offers high integration, small footprint, flexibility and ultra-low power consumption. The AX8052F151 is able to transmit and receive data rates of 1 - 600 kbps for ASK modulated data, 1 - 350 kbps for FSK modulated data and 10 - 600 kbps for PSK modulated data. With a sensitivity of -116  dBm for 1.2 kbps FSK and 15 dBm maximum output power at 868 MHz, the AX8052F151 offers an attractive link budget.

AX8052 microcontroller core

The AX8052F151 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.
AX8052F151 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 AX5052F151 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 AX5052F151 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.
AX8052F151 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 AXSEM RF ICs. It is suited for real performance tests using professional lab equipment, as well as for application code development.  AXSEM offers both the AX-RadioLab GUI as well as the advanced graphic integrated development environment AX8052-IDE together with the freely usable SDCC C-compiler to go with it.
