Manufacturer: Description:The block diagram in Figure 1 shows the relationships between the major control and memory sections of the MEM2012T25R0T0S1. The MEM2012T25R0T0S1 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. |
