2 / 117 page  2 T89C51RB2/RC2 4105D–8051–10/06 a more versatile serial channel that facilitates multiprocessor communication (EUART) and a speed improvement mechanism (X2 mode). Pinout is the standard 40/44 pins of the C52. The fully static design reduces system power consumption of the T89C51RB2/RC2 by allowing it to bring the clock frequency down to any value, even DC, without loss of data. The T89C51RB2/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 T89C51RB2/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.
