Asus Chromebook C223NA Schematic
Technical Specifications
Technical Summary
This schematic covers the C223NA, C423NA, and C523NA motherboard platforms, revision 1.2, dated May 31, 2018. The core architecture is built around an Intel Apollo Lake CPU with dual-channel LPDDR4 4GB memory. System management is handled by an NPCX586GA0BX EC/KBC, while audio processing uses a DA7219-02VB6 codec and a MAX98357AETE+ speaker amplifier. The BIOS is stored on a SPI ROM. Power management includes a Type-C charger. Connectivity features include WLAN BT, a uSD card reader, and multiple Type-C and Type-A ports. The board also integrates a BMI 160 and BMM 150 sensor for gyroscope, accelerometer, and compass functions, along with eMMC storage.
