Class OneWireContainer09
1-Wire container for 128 byte Add-Only memory (EPROM) iButton, DS1982 and 1-Wire Chip, DS2502. This container encapsulates the functionality of the 1-Wire family type 09 (hex)
The iButton package for this device is primarily used as a read/write portable memory device. The 1-Wire Chip version is used for small non-volatile storage.
Features
- 1024 bits (128 bytes) Electrically Programmable Read-Only Memory (EPROM) communicates with the economy of one signal plus ground
- EPROM partitioned into four 256-bit (32-byte) pages for randomly accessing packetized data
- Each memory page can be permanently write-protected to prevent tampering
- Device is an "add only" memory where additional data can be programmed into EPROM without disturbing existing data
- Architecture allows software to patch data by superseding an old page in favor of a newly programmed page
- Reads over a wide voltage range of 2.8V to 6.0V from -40@htmlonly °C @endhtmlonly to +85@htmlonly °C @endhtmlonly; programs at 11.5V to 12.0V from -40@htmlonly °C @endhtmlonly to +50@htmlonly °C @endhtmlonly
Alternate Names
- D2502
Memory
The memory can be accessed through the objects that are returned from the
getMemoryBanks
method.
