Description
- OVERVIEW
- The block diagram in Figure 1 shows the relationships between the major control and memory sections of the DS2505. The DS2505 has three main data components: 1) 64-bit lasered ROM, 2) 16384-bits EPROM Data Memory, and 3) 704 bits EPROM Status Memory.
- FEATURES
- 16384 bits Electrically Programmable Read Only Memory (EPROM) communicates with the economy of one signal plus ground
- Unique, factory-lasered and tested 64-bit registration number (8-bit family code +48-bit serial number + 8-bit CRC tester) assures absolute traceability because no two parts are alike
- Built-in multidrop controller ensures compatibility with other 1-WireNet products
- EPROM partitioned intosixty-four 256-bit pages for randomly accessing packetized data records
- 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
- 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 16.3 kbits per second
- 8-bit family code specifies DS2505 communications requirements to reader
- Presence detector acknowledges when the reader first applies voltage
- Low cost TO-92 or 6-pin TSOC surface mount package
- Reads over a wide voltage range of 2.8V to 6.0V from -40°C to +85°C; programs at 11.5V to 12.0V from -40°C to +50°C
