FlexMemory versus Traditional EEPROM
Attribute Traditional Embedded EEPROM FlexMemory
Read-while-write with program memory Yes Yes
Granularity Byte write/erase Byte write/erase
Write time ~1.5msec (byte write only) ~100usec (word or byte program, brown-outs w/o loss or corruption of data)
Erase + write time ~5-10 msec ~750 usec + ~750 usec (1.5 msec)
Guaranteed endurance 50-300K cycles (fixed) SoC implementation and user configurable, can exceed 10M cycles
Minimum write voltage ≥2.0V 1.71V
Flexibility Fixed by part number Programmable trade-off - quantity vs. endurance
