BT817Q-T

Overview

The BT817Q-T is a Bridgetek EVE (Embedded Video Engine) video IC featuring capacitive touch support and ASTC compression. It operates on a 3.3 V supply with a maximum current draw of 30 mA. The device supports display resolutions up to 2K x 2K pixels and includes 2 MB of onboard RAM. It utilizes an SPI interface for communication and is housed in a VQFN-64 package. The component functions within a temperature range of -40°C to +85°C, making it suitable for industrial applications requiring high-performance graphics and touch integration.

Feature Summary

• Integrated EVE architecture with 2 MB RAM for graphics and touch processing
• Supports capacitive touch input with multi-touch capabilities
• ASTC texture compression reduces memory bandwidth requirements
• SPI interface for host controller connectivity

Applications

• Industrial HMI panels requiring robust touch interaction
• Medical device displays with strict environmental operating ranges
• Automotive infotainment systems needing high-resolution graphics
• Smart home control interfaces with integrated touch controls

Procurement Notes

Verify the specific suffix 'T' indicates tray packaging when ordering. Confirm RoHS compliance status through official Bridgetek documentation prior to procurement. Ensure ESD handling procedures are followed due to moisture sensitivity classification. Cross-reference the Mouser part number 895-BT817Q-T for accurate distributor identification.

Selection Notes

Select the BT817Q-T when 2 MB RAM and capacitive touch are required. Compare against the BT816Q-T if resistive touch or lower resolution (800x600) suffices. Ensure the host system supports SPI communication. Verify that the 3.3 V power rail meets the 30 mA peak current requirement during active display updates.

Part Context

The BT817Q-T belongs to the Bridgetek BT817/8 series of Embedded Video Engines. It is designed to offload graphics rendering and touch processing from the main application processor. This series integrates display drivers, audio output, and touch controllers into a single chip, reducing PCB complexity and component count for embedded display solutions.

Replacement Considerations

The BT816Q-T serves as a functional alternative for applications requiring only resistive touch and 800x600 resolution. For higher performance needs, the BT881Q-T offers similar features in a QFN-48 package. Verify pin compatibility and software library support before substituting any component in an existing design.
