    Which PICs have static RAM that doesn't get erased when you power-off?

    Too bad. I had high hopes for this.

    From Micros web site
    Static RAM or SRAM
    Static Random Access Memory. Program memory you can Read/Write on the target board that does not need refreshing frequently.
    Look to you data sheets. Many have SRAM.

    Does the static ram retain its contents when you power off?

    Sorry, I haven't been paying attention to this thread... I implied (perhaps erroneously) that all Static RAM is non-voltatile (trouble when reading too many different manufacturers product Datasheets). Only some types are. I haven't gone through all of Microchips offerings so I can't answer if there is non-volatile RAM amongst their product range - a question that could be posed to their technical enquiry line.
