Technical Summary

The Inventec A10 motherboard, revision A02 dated 03-Oct-2019, is built around the CML U42/U62 CPU platform. Graphics processing is handled by an NVIDIA GPUN N17S-G2/G5 discrete GPU. The embedded controller is an NPCE285UA0DX in a 128-pin LQFP package. System firmware is stored on a Winbond SPI ROM. The charging architecture uses a BQ24780S charger IC, accepting power from a DCIN jack adapter to manage PVBAT. Memory configuration supports DDR4 1.2V at 2400MHz or 2667MHz. The audio subsystem features both ALC1304 and ALC256M codecs. Power management is distributed across multiple regulators including Intersil ISL95808HRZU, Renesas ISL95880HRTZ, and various Silergy and Richtek converters. Connectivity includes RTS5441P and RTS5450 USB hub controllers, an RTS5170 card reader, and PS8330B/PS8407/PS8713B LAN ICs. The board also integrates an HDMI 4K repeater and CNVI-based WLAN/BT.
