I am looking for the an ARM7 system with the following features:
- 256kB on-chip SRAM.
- Ethernet MAC (Could be external)
- USB Device interface (Could be external)
- External interface for several MB of flash memory.
My application:
- No more than about 10 MIPS processing speed, plus any extra for servicing Ethernet and USB.
- Cost sensitive.
- Planned to stay in production for 5 years.
- Long-term availablity is an important consideration.
So far I am looking at the Atmel AT91R40008 with an external solution for Ethernet and USB. Should I be looking at ARM9, or maybe a Motorola processor?
regards, Johnny.
