'[EE]: RAM -> FLASH'

Hi all,

Does anyone know of a device that you could write a few K of data to RAM
and when needed dump that RAM directly to flash?

I may need a project that uses a continuous A2D writing to a largish
circular buffer. When a trigger event occurs, I need to save the buffer
contents to FLASH type memory.

Perhaps, lithium battery backed RAM may do too.

Yes - if you need the large RAM anyway, just battery-back it.

AT89S8252 and friends probably. 2K Flash data on chip. There are other
combinations available, also from other firms.
