Texas Instruments makes the TMS370 family (no, these do not emulate an
IBM 370 mainframe). As I recall, there are two branches to the family.
One is a 28 pin device, the other something like 68 pins. At least one
member in each branch has EEROM for program memory. The timers for
the 28 pin branch are not as fancy but I think you can do two PWM outputs.
The family sports both asynchronous and synchronous serial I/O; I don't
recall if the 28 pin branch has async I/O.

There is a branch of the National Semi COP800 family of microprocessors
that had members with 2 timers, async serial I/O and EEROM for both
program and data. COP8784CK and COP8788CK. These don't seem to have
made it into production. They appear in the 1988 Master Selection Guide
but not in the 1989 one. There is a ROM version of a device in this branch
that is in production. I think I heard that there is either an UV EPROM or
piggyback development device to support the ROM version.
