Perhaps an ARM9 or similar class of MCU will be better choice. Atmel/NXP/ST/etc have quite some parts. Maybe even an RTOS is warranteed in this case. Freescale ColdFire might be a good choice (some of them with built-in Ethernet and maybe LCD). According to some rumors, Microchip will soon come out 32bit PIC32. Not so sure what is the core based. Not ARM according to the rumor. Xiaofan -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
