Hey everybody,
I am using DS89C450 uC in my final year project. There are a few doubts i would like to clarify.
1)The datasheet says it is compatible with 80C52 micro. But it has EA pin on it. The 89C52 micro has EA(bar) i. it is active low. Is it the same or the Dallas' micro is active high. 2)I have gone through the ISP prgramming pdf available on maxim's site. The question is can i program my DS89C450 by connecting EA(bar) to VCC, PSEN(bar) to GND and RST to VCC. rather making use of HC 125 buffer.
Regards, Shirazi
