Page 29: Real Time Clock (Rtc)
System Features Real Time Clock (RTC) The Bengal features a real-time clock/calendar (RTC) circuit. The RTC can be set using the BIOS Setup utility. The Bengal supplies RTC voltage in S5, S3, and S0 states, but requires an external +2.75 V to +3.3 V battery connection to maintain RTC functionality and RTC CMOS RAM when the Bengal is not powered. -
Page 30: Table 9: Pci/104-Express
System Features Integrator’s Note: The PCIe/104 OneBank version of the interface does not implement the Bank 2 or Bank 3 connectors. CAUTION: No attempt should be made to add SUMIT-based products to the OneBank connector. The SUMIT interface is not mechanically or electrically compatible with the OneBank interface. Attempting to use SUMIT expansion modules will damage the OneBank connector and void the warranty. -

Page 37: Power Button
Interfaces and Connectors Power Button Connector J18 includes an input for a power button. Shorting J18 pin 41 to ground causes the board to enter an S5 power state (similar to the Windows Shutdown state). Shorting it again returns the board to the S0 power state and reboots the board. The button can be configured in Windows to enter an S3 power state (Sleep, Standby, or Suspend-to-RAM), an S4 power state (Hibernate or Suspend-to-Disk), or an S5 power state (Shutdown or Soft-Off). -
Page 38: Pushbutton Reset
Interfaces and Connectors Pushbutton Reset Connector J18 includes an input for a pushbutton reset switch. Shorting J18 pin 40 to ground causes the Bengal to reboot. The input can be connected to ground using the normally open contacts of a pushbutton switch or a relay, or with a switching transistor (open-collector or open-drain) capable of sinking 1 mA. -
Page 39: Video Interfaces
Interfaces and Connectors Video Interfaces The Bengal incorporates the Intel Gen-7 graphics core with four Execution Units and Turbo Boost. It supports two independent displays. It also supported formats including DirectX 11, OpenGL 3, VP8, MPEG2, H.264, VC1, 2 HD streams (1080p@30fps), Flash and WMP support. Analog and dual mini DisplayPort video interfaces support Extended Desktop, Clone, and Twin display modes. -

Page 53: Thermal Considerations
By itself, the heat plate is not a complete thermal solution. Integrators should either implement a thermal solution using the accessories available from VersaLogic or develop their own thermal solution that attaches to the heat plate, suitable for environments in which the EPMe-30 will be used. -
Page 54: System-Level Considerations
Thermal Considerations System-level Considerations The EPMe-30 thermal solutions – either the HDW-406 heat sink alone or with the HDW-407 fan – are part of the larger thermal system of the application. Other PC/104 boards stacked under the Bengal and any other nearby heat sources (power supplies or other circuits), all contribute to how the EPMe-30 will perform from a thermal standpoint. -
Page 55: Cpu Thermal Trip Points
