Part Details:

19-0729; Rev 1; 9/07 PECI-to-I2C Translator MAX6621 General Description Features The MAX6621 PECI-to-I2C translator provides an effi- 400kbps I2C-Compatible, 2-Wire Serial Interface cient, low-cost solution for PECI-to-SMBusTM/I2C proto- +3V to +3.6V Supply Voltage col conversion. The PECI-compliant host reads temperature data directly from up to four PECI-enabled PECI-Compliant Port CPUs. Interrupts are generated when the measured PECI-to-I2C Translation temperature exceeds the high-temperature limit and ALERT Output causes ALERT to assert. The RESET input allows the RESET Input (May Be Disabled as a Factory host to reset the I2C bus in the event of a communica- Option) tion error. Programmable Temperature Offsets The I2C interface provides an independent serial com-munication channel to communicate synchronously with -20°C to +120°C Operating Temperature Range peripheral devices in a multiple master or multiple slave VREF Input Refers Logic Levels to the PECI system. This interface allows a maximum serial-data Supply Voltage rate of 400kbps. Automatic I2C Bus Lockup Timeout Reset The MAX6621 is designed to operate from a +3.0V to Lead-Free, 10-Pin µMAX® Package +3.6V supply voltage and ambient temperature rangeof -20°C to +120°C.
