RF Features & Applications
- 1024 bits of EEPROM memory are partitioned into four pages of 256 bits each for structured data storage
- Individual memory pages can be permanently write-protected or placed in EPROM-emulation mode where bits only change from 1 to 0
- Reads and writes operate over a wide 2.8 V to 5.25 V range from -40°C to +85°C on a single-contact 1-Wire bus
- Communicates at 15.4 kbps standard or 125 kbps overdrive speed over one digital signal for minimal pin cost
- IEC 61000-4-2 level 4 ESD protection of ±8 kV contact and ±15 kV air typ survives harsh handling environments
- 64-bit ROM registration number guarantees absolute device identity in multidrop 1-Wire networks
- 200k write/erase endurance cycles at +25°C and 40-year data retention at +85°C for long-life product records
- Switchpoint hysteresis and built-in filtering optimize reliability in noisy electrical environments
