BT817Q-R

Overview

The BT817Q-R is a video IC from Bridgetek featuring the EVE4 Advanced Embedded Video Engine with ASTC support and capacitive touch capability. It operates on a 3.3V supply with a current draw of 30 mA, functioning within a temperature range of -40°C to +85°C. The component utilizes a VQFN-64 package and communicates via SPI interface. It integrates 1MByte graphics RAM and supports external QSPI NOR flash up to 2Gbit for storing graphic elements.

Feature Summary

EVE4 engine with Adaptive Scalable Texture Compression (ASTC) for memory-efficient graphics
Capacitive touch screen support with up to 5-point detection and hardware touch tag tracking
Integrated 1MByte graphics RAM eliminating the need for external frame buffer RAM
Quad SPI host interface supporting single, dual, or quad modes at speeds up to 30MHz

Applications

Point of Sales Machines
Multi-function Printers
Instrumentation
Home Security Systems
Medical Appliances

Procurement Notes

Verify the specific ordering suffix 'R' corresponds to taped and reel packaging containing 3000 pieces per reel as defined in the datasheet part number table. Confirm that the required voltage levels for VCCIO1, VCCIO2, and VCCIO3 align with the system design, as these I/O supplies support 1.8V, 2.5V, or 3.3V. Ensure moisture sensitivity handling protocols are followed during assembly.

Selection Notes

Select the BT817Q-R when capacitive multi-touch functionality is required, distinguishing it from the resistive touch variant BT818Q-R. This model supports resolutions up to 1 Mega pixel and includes built-in audio output capabilities. Consider the VQFN-64 package dimensions and thermal pad requirements for PCB layout. Verify compatibility with the host MCU's SPI interface speed and mode constraints.

Part Context

The BT817Q-R belongs to the BT817/8 series, representing the fourth generation of EVE technology. It shares the same VQFN-64 package and core architecture with the BT818Q-R, differing primarily in touch screen interface type. The 'Q' indicates Quad SPI support, while 'R' denotes the reel packaging format.
