  • Product introduction

DS28EC20A 20,480-bit 1-Wire®EEPROM is organized into 80 x 256-bit memory

Key features

  • The division of 20480-bit non-volatile (NV) EEPROM into 80-256-bit pages
  • 8-page memory pages (blocks) individuals can be permanently write-protected or in OTP EPROM emulation mode ("Write 0")
  • Read and write access are highly backward compatible with legacy devices (e.g., DS2433)
  • Strict read/write protocol The 256-bit scratchpad ensures data transmission integrity
  • 200K write/erase cycle endurance between +25°C
  • A unique factory-programmed 64-bit registration number ensures error-free device selection and absolute partial approval
  • Switching point hysteresis and filtering optimize performance in noisy environments
  • The communication host utilizes the 1-Wire protocol, at 15.4kbps or 90kbps
  • Low-cost TO-92 package
  • Business range: 5V±5%, -40°C to +85°C
  • Complies with IEC 1000-

description

The DS28EC20 is a 20480-bit 1-Wire®EEPROM with an organization of 80 256-bitsmemoryPage. An additional page reservation control feature. The data is written to a 32-byte scratchpad, verified, and then copied to EEPROM memory. As a special feature, the 8 memory page blocks can be write-protected or EPROM emulation mode, where the bits can only change from 1 to 0 state. The DS28EC20 communicates a single-conductor 1-Wire bus. communication, following the standard 1-Wire protocol. Each device has its own immutable, unique 64-bit ROM registration number. Registration numbers are devices that are used to address a multipoint 1-Wire network environment.
