MAX6618

19-0730; Rev 1; 8/07 www.DataSheet4U.com PECI-to-I2C Translator General Description The MAX6618 PECI-to-I2C translator provides an efficient, low-cost solution for PECI-to-SMBusTM/I2C protocol conversion. The PECI-compliant host reads temperature data directly from up to four PECI-enabled CPUs. 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 MAX6618 is designed to operate from a +3.0V to +3.6V supply voltage and ambient temperature range of -20°C to +120°C. ♦ ♦ ♦ ♦ ♦ ♦ Features ♦ 400kbps I2C-Compatible, 2-Wire Serial Interface +3V to +3.6V Supply Voltage PECI-Compliant Port PECI-to-I2C Translation Programmable Temperature Offsets -20°C to +120°C Operating Temperature Range VREF Input Refers Logic Levels to the PECI Supply Voltage ♦ Automatic I2C Bus Lockup Timeout Reset ♦ Lead-Free, 10-Pin µMAX® Package MAX6618 Applications Servers Workstations Desktop Computers PART MAX6618AUB+ MAX6618AUB+T Ordering Information TEMP RANGE -20°C to +120°C -20°C to +120°C PIN-PACKAGE 10 µMAX 10 µMAX T = Tape and reel. +Denotes a lead-free package.
