DS28E04-100

4096-Bit Addressable 1-Wire EEPROM with PIO

GENERAL DESCRIPTION

The DS28E04-100 is a 4096-bit, 1-Wire EEPROM

chip with seven address inputs. The address inputs

are directly mapped into the 1-Wire 64-bit Device ID

Number to easily enable the host system to identify

the physical location or functional association of the

DS28E04-100 in a multidevice 1-Wire network en-

vironment. The 4096-bit EEPROM array is configured

as 16 pages of 32 bytes with a 32 byte scratchpad to

perform write operations. EEPROM memory pages

can be individually write protected or put in EPROM-

emulation mode, where bits can only be changed

from a 1 to a 0 state. In addition to the memory, the

DS28E04-100 has two general-purpose I/O ports that

can be used for input or to generate level and/or

pulse outputs. Activity registers also capture port

activity for state change monitoring. The DS28E04-

100 communicates over the single-contact 1-Wire

bus. The communication follows the standard Maxim

1-Wire protocol.
