Hardware monitoring IC chip supports PECI 3.0 interface

Nuvoton Technology Corp. has launched a new discrete Hardware Monitoring device -- NCT7802Y to support the Intel PECI 3.0 (Platform Environment Control Interface) specification, and provides accurate voltage and temperature monitoring, patented SMART FAN IV fan control algorithms and advanced system protection mechanisms to ensure efficiency and reliability of Industrial PC or Thin Client system in applications such as desktop, notebooks, servers, VGA cards, projectors, and game console apps.

As explained by Nuvoton NCT7802Y consists of an internal 10-bit ADC is built inside it, to convert the monitored temperature into accurate in ±1? values and the remote inputs can be connected to CPU/GPU thermal diode or any thermal diode sensors and thermistor, moreover, it can get latest Intel CPU temperature directly via Intel PECI3.0 interface. Along with temperature and voltage sensors, it monitors up to 3 fan inputs and control 3 fan outputs (DC or PWM mode) by SMART FAN IV mode or Manual mode. The SMART FAN IV of NCT7802Y supports multi-zoned linear temperatures and fan speed mapping with hysteresis, to provide an easy method to implement quiet and cooling solution with maximum safety and flexibility says Nuvoton.

Nuvoton says the NCT7802Y implements an array of system alert features; there are several pure hardware event pinssuch as ALERT#, T_CRIT#, and RESET #, SMI # and BEEP alarm signals, and all threshold values could be set for immediately activating system protection and several SMBus addresses could be set for flexible system design.

Nuvoton's Hardware Monitoring IC solutions continue to be customer's primary choice. As the system hardware's first protection role, the Nuvoton Hardware Monitoring ICs series always integrate the most important and up-to-date hardware monitoring functions, also perfect the system stability and overall functionalities with excellent quality, efficiency.
