I'm starting a new project and I intend to use an 8051 derivative.
Specifically, I'm looking for a chip that has at least 3MIPS, 64K
FLASH, an SPI port, and must be RoHS compliant.

The real reason that I'm posting is that I want to use a chip(s) that
are truly second sourced. We intend to produce this product for maybe
10 years or so, so we don't want to have to be concerned about having
a chip manufacture stopping production.

For example, I know that the Philips's P89V51RD2 is second sourced by
SST's SST89E516RD2. Atmel makes an AT89C51RD2, but the SPI signals
are pined out differently then the first two chips. But this is the
only second sourced chip that I can find with the above mentioned
requirements. I was wondering is anyone knows of other 8051 type chips
that are second sourced.

Thanks George
