This document presents a comprehensive block diagram of the Apollo4 Blue Lite System-on-Chip (SoC), showcasing its architecture and connectivity to various peripheral devices. The diagram highlights the power management system, including USB power input, over-voltage and over-current protection (OVP/OCP), and a Li-ion battery charging circuit managed by the BQ24210DQCT. Power regulation is achieved through BVP62840 buck converters, providing stable voltage rails for different SoC components.
The Apollo4 Blue Lite SoC (AMA4B2KL-KXR) interfaces with a range of sensors, including a PPG/ECG sensor (MAX86176ENX+), a G-Sensor (LSM6DSLTR), a light sensor, and a temperature sensor (MAX30208). Wireless connectivity is facilitated by the ATWINC1500B module, supporting both Bluetooth (BT:2402-2480MHz) and Wi-Fi (WIFI:2412-2462MHz) communication. The diagram also illustrates connections to external memory, such as EMMC and PSRAM, and a TFT Amoled display. Load switches (GLF71301) are used for power control of specific peripherals. The diagram provides a clear overview of the system's architecture and interconnections, aiding in design and debugging efforts.
