The memory can be partitioned into segments having different levels of write protection, thus preventing changes to certain data while allowing data changes to other portions of the memory. In addition to software write protection, the devices offer hardware write protection. Using the write protection input pin the system designer can protect specific blocks of the memory area reserved for configuration or serialization data, such as serial numbers or system setup parameters, from inadvertent changes. With these write protection features there is no need for additional components to permanently protect system configuration data. They are specified to operate from a low-voltage power source of 1.8 volts to 6.0 volts for read and program operations.
Standby current is only picoamperes.
Larger quantities are priced at significantly lower levels. Samples are available now, and production quantities are scheduled for the third quarter.
