The AX8052F143 is a true single chip narrow-band, ultra-low power RF-microcontroller SoC for use in licensed and unlicensed bands ranging from 70 MHz to 1050 MHz The on-chip transceiver consists of a fully integrated RF front-end with modulator and demodulator. Base band data processing is implemented in an advanced and flexible communication controller that enables user friendly communication. The AX8052F143 contains a high speed microcontroller compatible to the industry standard 8052 instruction set. It contains 64 Kbytes of FLASH and 8.25 Kbytes of internal SRAM. The AX8052F143 features 3 16-bit general purpose timers with capability, 2 output compare units for generating PWM signals, 2 input compare units to record timings of external signals, 2 16-bit wakeup timers, a watchdog timer, 2 UARTs, a Master/Slave SPI controller, a 10-bit 500 kSample/s A/D converter, 2 analog comparators, a temperature sensor, a 2 channel DMA controller, and a dedicated AES crypto controller. Debugging is aided by a dedicated hardware debug interface controller that connects using a 3-wire protocol (1 dedicated wire, 2 shared with GPIO) to the PC hosting the debug software. While the radio carrier/LO synthesizer can only be clocked by the crystal oscillator (carrier stability requirements dictate a high stability reference clock in the MHz range), the microcontroller and its peripherals provide extremely flexible clocking options. The system clock that clocks the microcontroller, as well as peripheral clocks, can be selected from one of the following clock sources: the crystal oscillator, an internal high speed 20MHz oscillator, an internal low speed 640 Hz/10 kHz oscillator, or the low frequency crystal oscillator. Prescalers offer additional flexibility with their programmable divide by a power of two capability. To improve the accuracy of the internal oscillators, both oscillators may be slaved to the crystal oscillator.
