Atmel 89C55 replacement

[Unomano]

Hi,
I want to replace 89C55 (20k ROM) in my project with other microcontroller which has more program memory. Does anybody know any MCU with the same package type and pinout.
10x.

I use P89C51RD2, P89V51RD2 from Philips.

What is a difference between RD2 and ED2?
