Technical Summary

This Wistron Caramel-1 SA reference design, documented under project code 91.4Y401.001 and document number A3262, is built around an Intel Penryn LV/ULV SFF processor paired with an Intel Cantiga-GS integrated graphics core and an Intel ICH9-M SFF southbridge. The platform supports two DDR3 SODIMM slots operating at 1067/800MHz. System management is handled by a Renesas H8S/2116 EC/KBC in a BG20V package, with SPI-FLASH for BIOS storage. Power delivery is managed by a TPS51221 system DC/DC converter, an ADP3808 battery charger/selector, and multiple VR controllers including BD3550, VT1311, VT451, and VT450. The board features a USB2514 USB hub, a BOAZMAN LAN controller, a PI3L500AZFEX HDMI level shifter, and an R5C811 card reader. Thermal monitoring is provided by MAX6622 and LM265 sensors. The PCB uses an 8-layer stackup.
