Technical Specifications
Technical Summary
This Apple J43 MLB DVT schematic, revision 6.5.0 dated April 9, 2013, documents a Haswell-based platform with LPDDR3 memory configured across four banks in dual-channel architecture (Channel A and B, each split into 0-31 and 32-63 bit ranges). The board integrates a GL3219 SD controller for the SD card reader interface. The schematic includes detailed power delivery sections such as CPU VR12.5/12.6 VCC regulation, PBus supply and battery charger, LPDDR3 supply, and LCD/KBD backlight driver. Connectivity is supported by Thunderbolt host controllers, a wireless connector, and an external USB3 connector. The document also specifies SMC (System Management Controller) support and project-specific constraints for memory, PCH, CPU, Thunderbolt, and camera subsystems.
