The GK7102 is a High Definition Video Encoder SoC (System on Chip) manufactured by Goke Microelectronics. It is widely used in the IP security camera and DVR (Digital Video Recorder) industry.

Here is a summary of the specifications and features typically found in the GK7102 datasheet, along with information on how to find the full document.

For embedded firmware developers, the datasheet provides a memory map. Key base addresses:

| Peripheral | Base Address (Hex) | Interrupt # | | :--- | :--- | :--- | | UART0 | 0x1000_0000 | 12 | | SPI0 (Nor Flash) | 0x1800_0000 | 18 | | I2C0 | 0x1800_8000 | 19 | | Timer 0-3 | 0x1300_0000 | 26-29 | | Video Encoder (H.264) | 0x2100_0000 | 45 | The Goke GK7102 is a High-Definition (HD) IP

Note on Boot Options: The GK7102 boots from an external SPI NOR flash (max 32MB). The first 4KB of flash must contain a valid boot header (magic number 0x4B474F for "GKO").

This is your first stop. The datasheet clearly stresses:

Pro tip from the datasheet: Power sequencing matters. VDD_IO should rise simultaneously or before VDD_CORE to avoid latch-up.

A typical GK7102 application (from the datasheet's "Typical Application Diagram") includes:

A unique aspect highlighted in the GK7102 datasheet is its flexible memory architecture. It supports SIP (System-in-Package) DDR2 memory, meaning the RAM is stacked within the same package as the processor. This reduces PCB layout complexity and electromagnetic interference (EMI), which is vital for compact camera designs. Alternatively, it supports external DDR2 up to 512Mb. For storage, the chip integrates a SD/SDIO controller and a NAND Flash controller. This allows the chip to boot directly from NAND or SPI NOR flash, store video footage locally on an SD card, and stream over Ethernet or Wi-Fi simultaneously.
