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 Dallas
Semiconductor 1-Wire protocol.
