General Description
The EMC1001 is a tiny SMBus temperature sensor
with ±1.5°C accuracy and two interrupts. Packaged in
a SOT23-6, the EMC1001 provides an accurate,
low-cost, low-current solution for critical temperature
monitoring in a PC or in embedded applications.
The EMC1001 generates two separate interrupts with
programmable thermal trip points. The THERM output
operates as a thermostat with programmable threshold
and hysteresis. The ALERT output can be configured
as a maskable SMBus alert with programmable win-
dow comparator limits, or as a second THERM output.
An efficient fan control system can be created since
this output may be used to control a fan.
A power-down mode extends battery life in portable
applications.
Each part number may be configured to respond to one
of four separate SMBus addresses.

3.3 SMBus Send Byte
The Send Byte protocol is used to set the Internal
Address Register to the correct Address. The Send
Byte can be followed by the Receive Byte protocol
(Section 3.4 “SMBus Receive Byte”) in order to read
data from the register. The send byte protocol cannot
be used to write data; if data is to be written to a regis-
ter, then the Write Byte protocol must be used (see
Section 3.1 “SMBus Write Byte”). The Send Byte
protocol is shown in Table 3-4.

3.4 SMBus Receive Byte
The Receive Byte protocol is used to read data from a
register when the internal register address pointer is
known to be at the right location (e.g., set via Send
Byte). This is used for consecutive reads of the same
register as shown in Table 3-5.

3.5 Alert Response Address
The ALERT/THERM2 output can be used as an
SMBALERT# as described in Section 4.3
“ALERT/THERM2 Output” The Alert Response
Address is polled by the Host whenever it detects an
SMBALERT#, i.e. when the ALERT/THERM2 pin is
asserted. The EMC1001 will acknowledge the Alert
Response Address and respond with its device
address as shown in Table 3-6.

3.6 SMBus Addresses
The EMC1001 is available in two versions (EMC1001
and EMC1001-1), each of which has four 7-bit slave
addresses that are enabled based on the pull-up resis-
tor on the ADDR/THERM pin. The value of this pull-up
resistor determines the slave address per Table 1-1.
Attempting to communicate with the EMC1001 SMBus
interface with an invalid slave address or invalid proto-
col results in no response from the device and does not
affect its register contents.
The EMC1001 supports stretching of the SMCLK
signal by other devices on the SMBus but will not
perform this operation itself. The EMC1001 has an
SMBus timeout feature. Bit 7 of the SMBus Timeout
Enable register enables this function when set to 1 (the
default setting is 0). When this feature is enabled, the
SMBus will timeout after approximately 25 ms of
inactivity.
