Product Introduction

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
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.
