The MAX6621 PECI-to-I
cient, low-cost solution for PECI-to-SMBus
col conversion. The PECI-compliant host reads
temperature data directly from up to four PECI-enabled
CPUs. Interrupts are generated when the measured
temperature exceeds the high-temperature limit and
causes ALERT to assert. The RESET input allows the
host to reset the I
tion error.
The I
munication channel to communicate synchronously with
peripheral devices in a multiple master or multiple slave
system. This interface allows a maximum serial-data
rate of 400kbps.
The MAX6621 is designed to operate from a +3.0V to
+3.6V supply voltage and ambient temperature range
of -20°C to +120°C.
