P89V51RB2/RC2/RD2  
8-bit 80C51 5 V low power 16/32/64 kB Flash microcontroller  
with 1 kB RAM  
Rev. 03 — 02 December 2004  
Product data  
1. General description  
The P89V51RB2/RC2/RD2 are 80C51 microcontrollers with 16/32/64 kB Flash and  
1024 bytes 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 (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.  
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  
field/update the application firmware makes a wide range of applications possible.  
The P89V51RB2/RC2/RD2 is also In-Application Programmable (IAP), allowing the  
Flash program memory to be reconfigured even while the application is running.  
2. Features  
80C51 Central Processing Unit  
5 V Operating voltage from 0 MHz to 40 MHz  
16/32/64 kB of on-chip Flash user code memory with ISP (In-System  
Programming) and IAP (In-Application Programming)  
Supports 12-clock (default) or 6-clock mode selection via software or ISP  
SPI (Serial Peripheral Interface) and enhanced UART  
PCA (Programmable Counter Array) with PWM and Capture/Compare functions  
Four 8-bit I/O ports with three high-current Port 1 pins (16 mA each)  
Three 16-bit timers/counters  
Programmable watchdog timer  
Eight interrupt sources with four priority levels  
Second DPTR register  
Low EMI mode (ALE inhibit)  
TTL- and CMOS-compatible logic levels
