1128 bits of 5V EEPROM memory partitioned into four pages of 256 bits, a 64-bit write-only secret and up to five general purpose read/write registers |
Write access requires knowledge of the secret and the capability of computing and transmitting a 160-bit MAC as authorization |
Secret and data memory can be write-protected (all or page 0 only) or put in EPROM-emulation mode ("write to 0", page 1) |
On-chip 512-bit SHA-1 engine to compute 160-bit MAC and to generate secrets |
Reads and writes over a wide voltage range of 2.8V to 5.25V from -40°C to +85°C |
Communicates to host with a single digital signal at 14.1kb per second using 1-Wire protocol |
On-chip 16-bit CRC generator for safeguarding data transfers |
Overdrive mode boosts communication speed to 125kbps |
Operating temperature range from -40°C to +85°C |
Minimum 10 years of data retention at 85°C |
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 |
Multidrop controller for 1-Wire net |
Digital identification and information by momentary contact |
Chip-based data carrier compactly stores information |
Data can be accessed while affixed to object |
Button shape is self-aligning with cup-shaped probes |
Durable stainless steel case engraved with registration number withstands harsh environments |
Easily affixed with self-stick adhesive backing, latched by its flange, or locked with a ring pressed onto its rim |
Presence detector acknowledges when reader first applies voltage |
