The P89V51RD2 is an 80C51 microcontroller with 64 kB Flash and 1024 bytes of
data RAM.
A key feature of the P89V51RD2 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 progra ....etc

I am a small time entrepreneur and need to program MCs from time to time.

Please give me the details\availability of parallel stand alone programmer
for P89V51RD2BN.
Would appreciate if it can also program Phillips LPC 1114 series .
Thanks and regards

Hi there!
Thanks for suggesting me. As we are working on our final year project we are supposed to use ADC0808 coz we have read something about it in our academics.I request u to please send me the C code for Interfacing LM35 With P89V51RD2 which also includes a LCD display for the reference of the temperature.I am using keil4 software for programming
The Conditions are
1) If the temp is b/w 23 degree to 26 degree the micro controller has to perform 4 operations which are
i)heater ON
ii)Blower ON
ii)Fan1 ON
iv)Fan2 OFF
2) If temp is 26 ....etc
