I am intending to use an Atmel AT89LP6440 in a new design. I noticed that this device does not show up in the supported devices list. The chip met the project requirements: non-volatile data memory, plenty of needed I/O pins, SPI/TWI, etc. Any suggestions? Thanks for any help sent!
All 8051s share the same instruction set - so the compiler will work.
the "support" mostly refers to simulation, having ready-made headers & startup code, etc.
Thanks so much for your input. However, how does the compiler know much built in memory, etc. the unsupported device has?
You tell it!

Thanks Andy for all your help! Will give a go now.
