BT880Q-R

Specialized Overview

The BT880Q-R is an embedded video controller IC from Bridgetek featuring the EVE technology. It integrates a graphics engine, audio control, and resistive touch interface within a VQFN-48 package. The device supports SPI communication with host microcontrollers and provides parallel RGB video output up to 60MHz pixel clock. It includes 256kB of internal graphics RAM and supports LCD resolutions such as 480x272, 320x240, 800x160, and 1024x120. Operating voltage ranges from 1.8V to 3.3V for I/O, with a 3.3V core supply. The component operates within a temperature range of -40°C to +85°C.

Specialized Procurement Notes

Verify the specific ordering suffix '-R' indicates taped and reel packaging containing 3000 pieces per reel. Confirm that the pinout remains backward compatible with the FT80x series if replacing legacy components. Ensure the host system supports the required SPI protocol modes and voltage levels for reliable integration.

Specialized Selection Notes

Select this model when resistive touch functionality is required alongside advanced graphics rendering. The BT880Q-R differs from the BT881Q variant by supporting only resistive touch rather than capacitive touch. Verify that the application requires the specific 48-pin VQFN package dimensions and thermal characteristics provided in the datasheet.

Specialized Part Context

This component belongs to the BT880/1 Embedded Video Engine series designed for Human Machine Interfaces. It serves as a successor to the FT80x series, offering enhanced sketch processing and object-oriented architecture. The part number identifies the specific resistive touch variant within the QFN-48 package family.

Specialized Replacement Considerations

The BT880Q-R is pinout backward compatible with the FT800Q series. Designers replacing FT800Q components can utilize this part without modifying the PCB layout, provided the software is updated to support the new instruction set and features.
