P89V51RB2/RC2/RD2
8-bit 80C51 5 V low power 16/32/64 kB flash microcontroller
with 1 kB RAM
Rev. 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 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.
