Description  
AT8xC51Rx2 microcontrollers are high performance ROM versions of the 80C51 8-bit  
microcontrollers. They contain a 0K, 16K or 32K bytes ROM memory block for  
program.  
The microcontrollers retain all features of the Atmel 80C52 with 256 bytes of internal  
RAM, a 7-source 4-level interrupt controller and three timer/counters.  
In addition, the microcontrollers have a Programmable Counter Array, an XRAM of  
1024 byte, a Hardware Watchdog Timer, a Keyboard Interface, a more versatile serial  
channel that facilitates multiprocessor communication (EUART) and a speed improve-  
ment mechanism (X2 mode).  
The microcontrollers have 2 software-selectable modes of reduced activity and 8 bit  
clock prescaler for further reduction in power consumption. In Idle mode, the CPU is  
frozen while the peripherals and the interrupt system are still operating. In the Power-  
down mode, the RAM is saved and all other functions are inoperative.
