Introduction

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.
