#79179 - RE: FLASH OR EEPROM ??? Responding to: ???'s previous message |
hi,
Is the data storage area EEPROM which can byte-write, or FLASH, which cannot, but has a simulated byte-write using ram ? You should read the datasheet once again. Page 91 says you about EEPROM of ED2: Data is written by byte to the EEPROM memory block as for an external RAM memory. [my comment: "as for very slooooooow external RAM" because write cycle takes 7..17ms] ...and page 95 says you about Flash of RD2/ED2: The 64-K byte Flash is programmed by bytes or by pages of 128 bytes. Regards, Oleg |
