AT89C51RB2/RC2
4180E–8051–10/06
The AT89C51RB2/RC2 retains all features of the 80C52 with 256 Bytes of internal
RAM, a 9-source 4-level interrupt controller and three timer/counters.
In addition, the AT89C51RB2/RC2 has a Programmable Counter Array, an XRAM of
1024 Bytes, a Hardware Watchdog Timer, a Keyboard Interface, an SPI Interface, a
more versatile serial channel that facilitates multiprocessor communication (EUART)
and a speed improvement mechanism (X2 mode).
The Pinout is the standard 40/44 pins of the C52.
The fully static design reduces system power consumption of the AT89C51RB2/RC2 by
allowing it to bring the clock frequency down to any value, even DC, without loss of data.
The AT89C51RB2/RC2 has 2 software-selectable modes of reduced activity and 8-bit
clock prescaler for further reduction in power consumption. In Idle mode, the CPU is fro-
zen while the peripherals and the interrupt system are still operating. In power-down
mode, the RAM is saved and all other functions are inoperative.
The added features of the AT89C51RB2/RC2 make it more powerful for applications
that need pulse width modulation, high speed I/O and counting capabilities such as
alarms, motor control, corded phones, and smart card readers.
