1. Writing to Address 0x0F causes the NVT210 to perform a single measurement. It is not a data register, and it does not matter what data is
written to it.
2. THERM
limit for MSOP8 package = 85癈, THERM
limit for WDFN8 package = 108癈.
Serial Bus Interface
Control of the NVT210 is carried out via the serial bus.
The NVT210 is connected to this bus as a slave device, under
the control of a master device.
The NVT210 has an SMBus/I
2
C timeout feature. When
this is enabled, the SMBus/I
2
C times out after typically
25 ms of no activity. However, this feature is not enabled by
default. Bit 7 of the consecutive alert register
(Address = 0x22) should be set to enable it.
Addressing the Device
In general, every SMBus/I
2
C device has a 7-bit device
address, except for some devices that have extended 10-bit
addresses. When the master device sends a device address
over the bus, the slave device with that address responds.
The NVT210 is available with one device address, 0x4C
(1001 100b). An NVT210D is also available.
The NVT210D has an SMBus/I
2
C address of 0x4D
(1001 101b). This is to allow two NVT210 devices on the
same bus, or if the default address conflicts with an existing
device on the SMBus/I
2
C. The serial bus protocol operates
as follows:
1. The master initiates a data transfer by establishing
a start condition, defined as a high-to-low
transition on SDATA, the serial data line, while
SCLK, the serial clock line, remains high. This
indicates that an address/data stream follows. All
slave peripherals connected to the serial bus
respond to the start condition and shift in the next
eight bits, consisting of a 7-bit address (MSB first)
plus an R/W
bit, which determines the direction of
the data transfer, that is, whether data is written to,
or read from, the slave device. The peripheral
whose address corresponds to the transmitted
address responds by pulling the data line low
during the low period before the ninth clock pulse,
known as the acknowledge bit. All other devices
on the bus remain idle while the selected device
waits for data to be read from or written to it. If the
R/W
bit is a 0, the master writes to the slave
device. If the R/W
bit is a 1, the master reads from
the slave device.
2. Data is sent over the serial bus in a sequence of
nine clock pulses, eight bits of data followed by an
acknowledge bit from the slave device. Transitions
on the data line must occur during the low period
of the clock signal and remain stable during the
high period, since a low-to-high transition when
the clock is high can be interpreted as a stop
signal. The number of data bytes that can be
transmitted over the serial bus in a single read or
