Technical Specifications
Technical Summary
This Lenovo Miix730 & ThinkX1 motherboard, manufactured by LC Future Center, is built on the Intel Kabylake Platform U-Series. The system management is handled by a MEC1650 EC/KBC, with the BIOS stored on a W25Q128FVPIQ SPI flash IC. Audio processing is split between an ALC3277 audio codec and an ALC3291 audio DSP. The board supports up to 16GB of LPDDR3 memory in a Memory Down configuration. Power management includes a BQ25700 battery charger, with core voltage regulation provided by NCP81218 and NCP81382 controllers. Thunderbolt connectivity is managed by a JHL6540 Alpine Ridge controller, while USB-C PD control is handled by TPS65982 and TPS65982D controllers. The HDMI interface uses a PS8338 level shifter, and a TS3USB31E USB hub IC is present for USB switching.
