Hi all.
Seems that Microchip have released the 12F1840, a new device which is able to write to its own program memory (!)
This means for the first time a $1 8 pin micro is able to modify its own program code...
In addition it also has 4 channel 10 bit A-D, 32MHz clock, 256 byte RAM, 256 byte E2PROM, CCP module, etc.
An example application is one reading data from a single MMC card, which implies it could also be used to read/write to SD cards as the large buffer can be used to store the required page writes.
I can think of a number of applications for this chip, even more so if they can increase the RAM to say 32Kbyte.
