i need an external nvram to interface with my 89c51 which ic is best to use and readily available?? i tried looking online for navrams, but all i get is EEPROM
i dont want to use EEPROM as a nvram, coz i need to read and write to it a lot...
help pleasE??
What would be the advantage over FRAM? Only 4 pins instead of many pins? pins? IIC FRAM and IIC EEPROM uses TWO (uC) pins. SPI FRAM and SPI EEPROM uses 4 (uC) pins. parallel FRAM and parallel EEPROM uses bunches of (uC) pins.
