NuPRO-E330

Serial ATA

The NuPRO-E330 provides six Serial ATA ports with data transfer
rates of up to 3.0 GB/s. Intel® Rapid Storage Technology supports
AHCI and RAID 0/1/5/10 functionality.

Universal Serial Bus (USB) 2.0

The NuPRO-E330 provides nine USB 2.0 ports supporting trans-
fer speeds up to 480 Mbps. All ports are high-speed, fullspeed,
and low-speed capable.

Hardware monitoring

A built-in, proactive hardware monitoring system in the Super I/O
monitors the CPU temperature, system fan speed, and voltage
levels to prevent overheating and/or component damage, effect
timely failure detection, and ensure stable supply of current for
critical components.

Watchdog Timer

The watchdog timer (WDT) monitors system operations based on
user-defined configurations. The WDT can be programmed for dif-
ferent time-out periods, such as from 1 to 255 seconds or from 1 to
255 minutes. The WDT generates a reset signal, then a reset
request, after failure to strobe it within the programmed time
period. A register bit may be enabled to indicate if the watchdog
timer caused the reset event. The WDT register is cleared during
the power-on sequence to enable the operating system to take
appropriate action when the watchdog generates a reboot.

Trusted Platform Module

The NuPRO-E330 optionally supports TPM ver. 1.2 (Trusted Plat-
form Module) for secure storage of keys, passwords and digital
certificates. Systems supporting TPM offer improved hard-
ware-based security in numerous applications, such as file and
folder encryption, local password management, S-MIME e-mail,
VPN and PKI authentication and wireless authentication for
802.1x and LEAP.
