Download DatasheetQuickLogic has developed a Customer Specific Standard Product (CSSP) to provide a camera interface bridge for the Texas Instruments (TI) Sitara AM335x processor line. It is designed to connect a camera sensor with a 10-bit parallel interface to the AM335x GPMC 16-bit multiplexed address/data bus. The reference design based on the PolarPro platform using an Aptina 3.1 MP sensor and is available from CircuitCo or BeagleBoard.org as part their Camera Cape for the BeagleBone system.This CSSP meets the specifications and requirements defined by TI to provide a complete high performance, low power CAMIF for the AM335x family of processors.
uickLogic’s CSSP technology, combining customizable silicon platforms, PSBs, and software drivers, can help OEMs and ODMs address the connectivity gap with a single chip solution optimized for the TI-based AM335x processor, enabling smaller PCB space requirements, much lower power consumption and lower BOM costs.
This connectivity solution offers designers the integration and flexibility to accelerate time-to-market and differentiation in the mobile market. The CSSP provides a unique combination of hard logic and ultra-low power programmable fabric based on QuickLogic’s patented ViaLink® technology for adapting as market conditions change, resulting in longer time-in-market. Custom drivers are provided for Linux, Android or Windows Mobile platforms.
The QuickLogic CSSP enhances processors to support emerging new standards and customer feature requirements, resulting in an improved user experience.
GPMC Interface Logic
The GPMC interface to the AM335x supports:
• 16-bit multiplexed address/data bus with address valid signal
• NOR Flash synchronous burst access, 16-word burst cycle
• Direct Memory Access (DMA) request for high-performance data transfer
• GPMC clock speed of 50 MHz
• 3.3 V support
CAMIF LogicThe CAMIF
logic connects to a camera sensor with a 10-bit parallel bus, such as the Aptina MT9T111. The CAMIF to the sensor supports:”
• Up to 30 frames per second (fps) CSSP-FPUN86-6494 — at WVGA or 12 fps at 2 MPCSSP-FPUN86-6517 — at 720p or 15 fps at1080p (2 MP)
• Up to 96 MHz clock speed
• RAW 10-bit Bayer pattern or RGB565 or YUV formats
• Camera pixel clock input
• Camera frame valid input
• Camera line valid input
• 2.8 V support
