SM768GX0B0000-AB

Microprocessors Overview

The SM768GX0B0000-AB is a display SoC manufactured by Silicon Motion, Inc., designed for USB and network display solutions. It features a single-core GPU operating at 340 MHz with integrated graphics acceleration capabilities. The device includes an embedded DDR3 controller supporting 256 MB of memory within a multi-chip module package to reduce PCB space. Connectivity options include one USB 3.0 port, four USB 2.0 ports, PCIe interface, LVDS, and HDMI v1.4 transmitter. It operates within a commercial temperature range of 0°C to 70°C and utilizes a 300-BGA (17x17 mm) surface-mount package.

Microprocessors Feature Summary

• Integrates Content Adaptation Technology (CAT) to compress display data and minimize bandwidth usage while maintaining low latency and high image quality.
• Includes a dedicated hardware video processing unit (VPU) that accelerates H.264 and MPEG4 decoding for efficient media playback.
• Features an embedded Arm Cortex-R5 processor to support real-time operating systems (RTOS) for time-critical applications.
• Supports multiple display outputs including dual-channel LVDS with independent layers, dual-channel VGA, and integrated HDMI.

Microprocessors Applications

• USB display adapters and monitors
• Universal docking stations
• Thin or zero clients
• Digital signage and video walls
• Point-of-sale (POS) terminals

Microprocessors Procurement Notes

Verify the specific suffix 'AB' against official Silicon Motion documentation to confirm halogen-free status and exact pinout configuration. Ensure compatibility with host interfaces such as USB 3.0 or PCIe before integration. Confirm that the 300-BGA package requires appropriate reflow soldering profiles suitable for the 17x17 mm footprint. Validate thermal management requirements for the 0°C to 70°C operating range in the final enclosure design.

Microprocessors Selection Notes

Select this component when a compact solution for 4K UHD display expansion via USB or PCIe is required. It is suitable for designs needing integrated video decoding without external processors. Consider the internal DDR3 memory option if board space constraints prevent adding external RAM chips. Evaluate the Arm Cortex-R5 capability if local RTOS execution is necessary for display control tasks.

Microprocessors Part Context

This model belongs to the SM768 series of display controllers from Silicon Motion. These SoCs are engineered to offload display processing from the main host CPU, reducing system power consumption. The series targets mobile and embedded display markets where size and efficiency are critical. The SM768GX0B0000-AB specifically integrates the necessary memory and interfaces for standalone display functionality.

Microprocessors Replacement Considerations

Consult official Silicon Motion substitution guides for verified alternatives. Generic cross-references may not match the specific MCM packaging or firmware requirements. Verify pin-to-pin compatibility and electrical specifications before considering any substitute part numbers.
