BT816Q-R

Overview

The BT816Q-R is a video IC from the Bridgetek BT81x series, functioning as an Embedded Video Engine (EVE) with integrated resistive touch control. It supports display resolutions up to SVGA (800 x 600 pixels) and features true 24-bit color depth. The device operates on a 3.3 V supply voltage with a typical current consumption of 22 mA. It utilizes Adaptive Scalable Texture Compression (ASTC) to optimize memory usage for graphics assets. The component communicates via an SPI interface and is housed in a VQFN-64 package suitable for surface mount technology.

Feature Summary

• Integrated resistive touch controller supporting 1 channel
• Supports SVGA resolution (800 x 600 pixels) with 24-bit color depth
• Utilizes ASTC algorithm for efficient memory management
• Operates within -40°C to +85°C temperature range

Applications

• Human-machine interfaces (HMI) requiring resistive touch input
• Industrial control panels
• Medical equipment displays
• Point-of-sale (POS) systems

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the supplier provides valid traceability for moisture-sensitive device handling requirements during procurement.

Selection Notes

Select the BT816Q-R over capacitive variants like the BT815Q-R when resistive touch screens are required. Verify that the host system supports the necessary SPI interface speeds. Check if external QSPI Flash is needed for asset storage, as this impacts system bandwidth and memory architecture design.

Part Context

This component belongs to the BT81x series of Advanced Embedded Video Engines. It represents a third-generation EVE product line that builds upon previous FT8xx generations by introducing ASTC compression. The series is designed to simplify GUI development through built-in smart widgets and animation capabilities.

Replacement Considerations

The BT815Q-R serves as a direct pin-compatible alternative if capacitive touch functionality is preferred instead of resistive. Both share the same VQFN-64 package and core EVE architecture.
