P89LV51RB2/RC2/RD2
8-bit 80C51 3 V low power 16/32/64 kB Flash microcontroller
with 1 kB RAM
Rev. 04 鈥?02 December 2004
Product data
1. General description
The P89LV51RB2/RC2/RD2 are 80C51 microcontrollers with 16/32/64 kB Flash and
1024 bytes of data RAM.
A key feature of the P89LV51RB2/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 (6 clocks per machine cycle) to
achieve twice the throughput at the same clock frequency. Another way to bene铿乼
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
In-System Programming (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
铿乪ld/update the application 铿乺mware makes a wide range of applications possible.
The P89LV51RB2/RC2/RD2 is also In-Application Programmable (IAP), allowing the
Flash program memory to be recon铿乬ured even while the application is running.
