A good point. We have very long product live cycles so component EOL is a big problem. Parts that don't reach a critical mass tend to be dropped. The AT91SAM7S256 comes in a TQFP64 too and has twice the memory.

The AT91SAM7x series can support a continuous bitstream at
3,84 Mbps * 2 = 7,68 Mbps with a 50 Hz interrrupt rate with a single SSC. You may need a little external H/W to convert the bitstream to a parallel format, if the LCD display cannot handle 1 bit serial transmission.-- Best Regards, Ulf Samuelsson This is intended to be my personal opinion which may, or may not be shared by my employer Atmel Nordic AB
Don't use the SPI, use the SSC.

The AT32uC3xxx chips were only released a few months ago and production volumes are not here yet (samples are!). The "A" version came in 100+ package, but the "B" version released this summer should be similar to the SAM7S in size.
