DS28E04-100 4096-bit 1-Wire®EEPROM

Key features:

  • 4096-bit EEPROM memory, divided into 16 pages, 256 bits
  • 7. Address input of physical location configuration
  • Two universal PIO pins with pulsed power generation capability
  • Individual memory pages can be permanently write-protected or OTP EPROM emulation mode ("write 0")
  • Communication is done with a single digital signal, and the host utilizes the 1-Wire protocol at 15.3kbps or 111kbps
  • Parasitic or V CC power supply
  • Conditional search based on PIO status or PIO activity
  • Switching point hysteresis and filtering optimize performance in noisy environments
  • Read and write from -40°C over a wide voltage range of 2.8V to 5.25V to +85°C
  • 16-pin SO package with 150 mils

Applications/Uses:

  • Access products, optical network units and PBXs
     
  • Accessory/PCB identification
     
  • Automatically configured modular systems such as central office switches, cellular base stations, access products, optical network units, and PBXs

description

The DS28E04-100 is a 4096-bit 1-Wire®EEPROM 7-address input chip. The 1-Wire 64-bit device ID number mapped directly to the address input makes it easy for the host system to identify the physical location or function association of multiple devices in a DS28E04-100 1-Wire network environment. The 4096-bit EEPROM array is configured as a 16-page 32-byte, 32-byte register to perform write operations. The EEPROM memory page can be written to either protect or EPROM simulation modes separately, and the mid-bit can only be changed from 1 to 0 state. In addition to memory, the DS28E04-100 has two universal I/O ports that can be used to input or generate horizontal and/or pulsed outputs. Activity registration also captures monitoring activity for port state changes. The DS28E04-100 communicates via a single-contact 1-Wire bus. Communication is based on the standard Maxim 1-Wire protocol.
