PECI-to-I C Translator

MAX621

General Description

Features

♦ 400kbps I C-Compatible, 2-Wire Serial Interface

The MAX6621 PECI-to-I C translator provides an effi-

cient, low-cost solution for PECI-to-SMBus^TM/I²C proto-

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

♦ +3V to +3.6V Supply Voltage

♦ PECI-Compliant Port

♦ PECI-to-I C Translation

♦ ALERT Output

♦ RESET Input (May Be Disabled as a Factory

host to reset the I C bus in the event of a communica-

Option)

tion error.

♦ Programmable Temperature Offsets

The I C interface provides an independent serial com-

peripheral devices in a multiple master or multiple slave

system. This interface allows a maximum serial-data

rate of 400kbps.
