DS28E04-100: 4096-Bit 1-Wire Addressable EEPROM with PIO
5 of 36
OVERVIEW
The block diagram in Figure 1 shows the relationships between the major control and memory sections of the
DS28E04-100. The DS28E04-100 has five main data components: 1) 64-bit device ID number, 2) 32-byte
scratchpad, 3) sixteen 32-byte pages of EEPROM, 4) Special Function Register, and 5) PIO Control Registers. The
hierarchical structure of the 1-Wire protocol is shown in Figure 2. The bus master must first provide one of the eight
ROM Function Commands, 1) Read ROM, 2) Match ROM, 3) Search ROM, 4) Conditional Search ROM, 5) Skip
ROM, 6) Resume, 7) Overdrive-Skip ROM or 8) Overdrive-Match ROM. Upon completion of an Overdrive ROM
command byte executed at standard speed, the device enters Overdrive mode where all subsequent
communication occurs at a higher speed. The protocol required for these ROM function commands is described in
Figure 14. After a ROM function command is successfully executed, the memory/control functions become
accessible and the master may provide any one of the nine Memory/Control Function commands. The protocol for
these commands is described in Figure 9.
All data is read and written least significant bit first.
