Specifications
Description Minimum Maximum Comment
EEPROM write/erase cycles 1 million Minimum valid over entire operating temperature
range.
EEPROM used in PLUS+1 ® controllers is rated for one million read/write cycles per sector. Sector size is 32
bits. When a value is written to EEPROM, all 32 bits in a particular sector are always written, regardless of
the size of the size of the saved value. If the value being saved in a sector is less than 32 bits (such as U8,
S16, BOLL) adjacent bits in the same EEPROM sector are rewritten with their previous value. The
implication of this memory property is that if two values are being written to the same memory sector,
the useful life of the sector is determined by the value being written most frequently. If that value
exceeds 1 million read/write cycles, all values in the sector may be compromised if the useful life is
exceeded.
