#187480 - Numbers always help
Responding to: ???'s previous message
Kurt Adam said:
Hello. I currently have a project Im working on that is coded for the 8051. However, I need more ports to connect external memory or on chip non-volatile RAM.

Is there an 8051 with more ports or on chip non-volatile RAM that someone could recomend. It would be much appreciated.


More ports than what ? How much 'NV RAM' ?

NV Ram is also probably not what you mean - do you want EEPROM, DataFLASH, or battery backed SRAM ?

You can get Serial EEPROM in small packages, as well as Serial SPI RAM, or there is FRAM if you need fast write turnaround.
