Dell Latitude E5250 LA-A891P
Technical Specifications
Technical Summary
This Dell Houston 12" UMA Dock motherboard, manufactured by Compal under board number LA-A891P revision 1.0 (A00), is built around the Intel Broadwell U processor platform. The system firmware is stored on a W25Q32BVSSIQ SPI flash with 64M 4K sector capacity, with a compatible W25Q64CVSSIQ alternative. Embedded controller functionality is handled by the SMSC KBC MEC5085. Audio is provided by an ALC3235 HDA codec, while networking is managed by an Intel Clarkville I218L LAN IC. The board supports DDR3L memory across four DIMM banks. Peripheral connectivity includes an O2 Micro OZ777FJ2LN-B card reader, a Parade PS8339 HDMI level shifter, a PI3USB3102ZLEX USB hub, and a TPS2544 USB power share controller. Security features include a discrete AT97SC3205 TPM and a BCM20793 NFC controller alongside a BCM5882 smart card reader.
