DS2505+ (MAXIM INTEGRATED PRODUCTS)
EPROM, Add-On, 1-Wire Net, 16Kbit, 16384bit, 2.8V to 6V, TO-92-3
The DS2505+ is a 16kB Add-only Memory with built-in multidrop controller ensures compatibility with other 1-Wire net products. The DS2505 16kB add-only memory identifies and stores relevant information about the product to which it is associated. This lot or product specific information can be accessed with minimal interface, for example a single port pin of a microcontroller. The DS2505 consists of a factory-lasered registration number that includes a unique 48-bit serial number, an 8-bit CRC and an 8-bit Family Code (0BH) plus 16kB of user-programmable EPROM. The power to program and read the DS2505 is derived entirely from the 1-Wire® communication line. Data is transferred serially via the 1-Wire protocol which requires only a single data lead and a ground return. The entire device can be programmed and then write-protected if desired.
- 16384-bit EPROM communicates with the economy of one signal plus ground
- EPROM partitioned into sixty-four 256-bit pages for randomly accessing packetized data records
- Each memory page can be permanently write-protected to prevent tampering
- Reduces control, address, data, power and programming signals to a single data pin
- Directly connects to a single port pin of a microprocessor and communicates at up to 16.3kbps
- 8-bit Family code specifies DS2505 communications requirements to reader
- Presence detector acknowledges when the reader first applies voltage
