1-WIRE INITIALIZATION SEQUENCE (RESET PULSE AND PRESENCE

WRITE TIME SLOTS
A write time slot is initiated when the bus master pulls the 1-Wire bus from a logic high (inactive) level to
a logic low level. There are two types of write time slots: Write 1 and Write 0. All write time slots must
be t
SLOT
(60μs to 120μs) in duration with a 1μs minimum recovery time, t
REC
, between cycles. The
DS2770 samples the 1-Wire bus line between 15μs and 60μs after the line falls. If the line is high when
sampled, a Write 1 occurs. If the line is low when sampled, a Write 0 occurs (see Figure 19). For the bus
master to generate a Write 1 time slot, the bus line must be pulled low and then released, allowing the line
to be pulled high within 15μs after the start of the write time slot. For the host to generate a Write 0 time
slot, the bus line must be pulled low and held low for the duration of the write time slot.
READ TIME SLOTS
A read time slot is initiated when the bus master pulls the 1-Wire bus line from a logic high level to logic
low level. The bus master must keep the bus line low for at least 1μs and then release it to allow the
DS2770 to present valid data. The bus master can then sample the data t
RDV
(15μs) from the start of the
read time slot. By the end of the read time slot, the DS2770 releases the bus line and allows it to be pulled
high by the external pull-up resistor. All read time slots must be t
SLOT
(60μs to 120μs) in duration with a
1μs minimum recovery time, t
REC
, between cycles. See Figure 19 for more information.
