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 EMI.

The ﬂash program memory supports both parallel programming and in serial ISP. Parallel

programming mode offers gang-programming at high speed, reducing programming costs

and time to market. ISP allows a device to be reprogrammed in the end product under

software control. The capability to ﬁeld/update the application ﬁrmware makes a wide

range of applications possible.

The P89V51RB2/RC2/RD2 is also capable of IAP, allowing the ﬂash program memory to

be reconﬁgured even while the application is running.
