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. 80C51 High Performance ROM 8-bit Microcontroller AT80C51RD2 AT83C51RB2 AT83C51RC2 |
