Lenovo ThinkBook 13x ITG Huaqin NB3629 Schematic
Technical Specifications
Technical Summary
The Lenovo Thinkbook plus gen2 (NB3629_MB&DB) motherboard, designed by Huaqin Telecom Technology, is built around the Intel TGL Lake UP4-Processor platform. The system utilizes dual-channel LPDDR4x memory down architecture, supporting configurations from 8GB to 16GB using Micron, Samsung, or Hynix memory packages. The embedded controller is an IT5571VG, and the audio subsystem is managed by a Realtek ALC3306-CG codec. The board features two SPI ROMs for firmware storage: a 16MB SPI ROM 1 and an 8MB SPI ROM 2. Power management includes a TPS65994 charging IC and a TPS65185 power IC. Connectivity is provided by an onboard WLAN/BT CNVIC module and an L860 M.2 KEY B WWAN module. The T1000 IC handles both the card reader and HDMI level shifting functions.
