Technical Summary
The Shuttle Inc A14HV motherboard is built on the Sandy Bridge processor platform paired with the Cougar Point PCH. System management is handled by an IT8518 Embedded Controller in a 128-pin LQFP package, with the BIOS ROM serving as the EC flash. The BIOS SPI flash is a Flash Rom 2 device in an 8-pin M-SOP package. Memory architecture consists of dual-channel DDR3 across two SO-DIMM slots. Audio is provided by a 92HD88B codec. The charging subsystem uses an OZ8602 charger IC. Power regulation is managed by ISL62881 for CPU core, OZ8116 and OZ815 for additional rails, OZ8291 and OZ8033 for sequencing, along with AM4826, AM4828, FP6137, APL5315, and APL1084 regulators. Networking, card reading, and USB hub functions are consolidated in the JMC251 controller. HDMI connectivity is supported by a CH7318B level shifter.
