   Maybe we all should go in sleep mode, until Microchip
starts producing devices on 0.13-micron low-k copper process.
This will dramatically decrease power consumption.
   There is a rumour, Microchip has intentions to become
partially a sort of a "fabless" supplier, based on the Xilinx and
others most advanced semiconductor 0.13-micron process
technologies.
   This strategy allows Microchip to focus on designing new product
architectures, software tools and intellectual property instead of
wasting money on legacy  technologies. For the first time it may
convert some microcontroller lines to 0.13-micron FPGA or CPLD,
using existing software.
   I don't know is this truth, or not, nobody knows, I think.
   Sounds great, cause we may get a chip with 16 bit core and a lot
of free cells to be configured via ICSP as one wish. It needs to be
implemented even for the only reason, Olin Lathrop seems to get
fed-up with this Bank switching and 8 bit data bus. :-0)
   Besides, storing program code in RAM instead of Flash increases
speed by many times.

   Mike.
