05 — 12 November 2009 Product data sheet 1.
General description The P89V51RB2/RC2/RD2 are 80C51 microcontrollers with 16/32/64 kB ﬂash and 1024 B of data RAM.
A key feature of the P89V51RB2/RC2/RD2 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 (six 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 E...
