AX8052F100
Ultra-Low Power
Microcontroller
OVERVIEW
The AX8052F100 is a single chip ultra−lowpower microcontroller
primarily for use in radio applications. The AX8052F100 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 AX8052F100 features 3 16−bit general purpose
timers with SD 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.
