P89V51RB2, P89V51RC2, and P89V51RD2 device highlight

Key Features: 80C51 core Superior price/performance ratio X2 clock mode IAP and ISP 16, 32, or 64 kilobytes of flash 1024 bytes of data RAM Low-power and power-down modes

A key feature of the P89V51RB2, P89V51RC2, and P89V51RD2 series of microcontrollers is its X2 mode option. The design engineer can choose to run the application with the conventional 80C51 clock rate (12 clocks per machine cycle) or select the X2 mode (6 clocks per machine cycle) to achieve twice the throughput at the same clock frequency. Another way to benefit from this feature is to keep the same performance by reducing the clock frequency by half, thus dramatically reducing the EMI.
