DS1972
description
The DS1972 is a 1024-bit 1-Wire®EEPROM chip that hosts four 256-bits, each ruggediA button-wrapped ® memory page. The data is written to an 8-byte register, verified, and then copied to EEPROM memory. As a special feature, the four memory pages can be individually write-protected or EPROM emulation mode, where the bits can only change from 1 to 0 state. The DS1972 communicates over a single-conductor 1-Wire bus. communication, following the standard 1-Wire protocol. Each device has its own immutable and unique 64-bit ROM registration number that is a factory lithography device. Registration numbers are used to address devices in multipoint, 1-Wire network environments.
Key features
- 1024-bit EEPROM memory, divided into 4 pages of 256 bits each
- Individual memory pages can be permanently write-protected or in EPROM emulation mode ("Write 0")
- Switching point hysteresis and filtering optimize performance in noisy environments
- IEC 1000-4-2 Level 4 ESD Protection (±8kV contact discharge, ±15kV air, typical)
- Read and write over 2.8V over a wide voltage range from -40°C to 5.25V to +85°C
- Communication with a single digital signal host uses the 1-Wire protocol, at 15.4kbps or up to 125kbps
