There's also the TI TUSB3410 (think that's the right part number)
which is 8052 based and communicates with external chips over a UART/GPIO. So no need to bitbang a memory bus. Program execution is out of RAM (can either be loaded from the host driver or else a I2C rom). Haven't used it yet, but am planning to try it with the 210x in the next week or so.
