The MAX6621 PECI-to-I²C translator provides an efficient, low-cost solution for PECI-to-SMBus™/I²C protocol 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 the active-low ALERT to assert. The active-low RESET input allows the host to reset the I²C bus in the event of a communication error.
The I²C interface provides an independent serial communication 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.
