... FUNCTION DESCRIPTIONS SC23M42 provides 256×8 bits EEPROM memory units and 32×1 protect units, and there is writing-protect for the former 32-bit bytes. Except PSC (Programmable Security Code) memory unit, all units are readable. The unit can be erased and written before the write-protect is active, or else the unit is only readable after the write-protect. ...
