Focuses on the MAX77693 and MAX77686

For technicians, these diagrams are essential for diagnosing common hardware failures:

Details the 2G/3G RF transceiver chip (often the PMB5712) and its associated antenna filters and oscillators. Samsung Galaxy S3 I9300 Schematic Diagram

Covers the Broadcom chips for GPS/GLONASS (BCM47511) and the Murata module for dual-band WiFi and Bluetooth 4.0.

The is a foundational document for engineers and repair professionals, detailing the intricate electrical architecture of one of Samsung's most historically significant flagship devices. Often referred to under its internal codename "MIDAS," the schematic reveals a multi-sheet layout that maps the phone's quad-core processing power, specialized radio frequency (RF) paths, and complex power management systems.

PMICs (Power Management Integrated Circuits), which regulate voltage across the motherboard. Maps the Wolfson Microelectronics audio hub

At the heart of the I9300's schematic is the . The diagram illustrates its tight integration with 1GB of LP DDR2 RAM and 16GB/32GB/64GB NAND Flash memory. Key technical highlights include: Often referred to under its internal codename "MIDAS,"

The schematic shows the circuitry for individual power gating across the four ARM Cortex-A9 cores, a design choice meant to reduce power consumption by shutting down inactive cores.
