Introduction

AI Translation

The DS28EC20 is a 20480-bit, 1-Wire EEPROM organized as 80 memory pages of 256 bits each. An additional page is set aside for control functions. Data is written to a 32-byte scratchpad, verified, and then copied to the EEPROM memory. As a special feature, blocks of eight memory pages can be write protected or put in EPROM-Emulation mode, where bits can only be changed from a 1 to a 0 state. The DS28EC20 communicates over the single-conductor 1-Wire bus. The communication follows the standard 1-Wire protocol. Each device has its own unalterable and unique 64-bit ROM registration number. The registration number is used to address the device in a multidrop 1-Wire net environment.

Features

AI Translation
  • 20480 Bits of Nonvolatile (NV) EEPROM Partitioned into Eighty 256-Bit Pages
  • Individual 8-Page Groups of Memory Pages (Blocks) Can Be Permanently Write Protected or Put in OTP EPROM-Emulation Mode ("Write to 0")
  • Read and Write Access Highly Backward Compatible to Legacy Devices (e.g., DS2433)
  • 256-Bit Scratchpad with Strict Read/Write Protocols Ensures Integrity of Data Transfer
  • 200k Write/Erase Cycle Endurance at +25°C
  • Unique, Factory-Programmed, 64-Bit Registration Number Ensures Error-Free Device Selection and Absolute Part Identity
  • Switchpoint Hysteresis and Filtering to Optimize Performance in the Presence of Noise
  • Communicates to Host at 15.4kbps or 90kbps Using 1-Wire Protocol
  • Low-Cost TO-92 Package
  • Operating Range: 4V to 5.25V, -40°C to +85°C
  • Operating Range: 3.135V to 3.465V, 0°C to +70°C
