Hi all,

Is there any '51 with large on chip RAM?
My limitations are:
1. Since I use HiLo All-11 chip programmer, I prever '51 in DIP/DIL package,
2. '51 with ISP feature is OK,
3. on chip RAM size is 1 kbyte minimum.

Now I use (always) 2 kbyte XRAM as UART stream buffer. I use it for PDU parsing.
