The FR series have the advantages of extra low power draw and you can use the FRAM as RAM which is magically non-volatile. Until this chip came out, the FR series were mostly smaller units with limited I/O. This one has it all, it's a really cool chip. FRAM is a really cool technology. You can read and write individual bytes with no penalty, it's very fast, it's low power. There's really no need for flash or EEPROM if you have FRAM. It's not quite as fast as SRAM, but that's not much of an issue. On these chips, if you run at the max 16MHz clock, FRAM runs with 1 wait state, which isn't much of a big deal. If there's something you need done at max speed, put those variables in SRAM. If you're clocking it at 8MHz or slower (reasonable if you're going for minimum power draw), the FRAM is as fast as RAM. Imagine, a microcontroller with 264kB of RAM, and 256kB of that is non-volatile. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
