BT81X (815/6) Advanced
Embedded Video Engine
Datasheet
The BT81X Series is an easy to use graphic
controllers targeted at embedded applications to
generate high-quality Human Machine Interfaces
(HMIs). It has the following features:
 Advanced Embedded Video Engine(EVE) with
high resolution graphics and video playback
 BT815/6 functionality includes graphic control,
audio control, and touch control interface.
 Support multiple widgets for simplified design
implementation
 Built-in graphics operations allow users with
little expertise to create high-quality displays
 Support Adaptive Scalable Texture Compression
(ASTC) format to save considerable memory
space for larger fonts and graphics images
 Support external QSPI NOR flash up to 2Gbit to
store and fetch graphic elements (image, font,
widget etc.)
 Support 4-wire resistive touch screen (BT816)
 Support capacitive touch screen with up to 5
touch point detection (BT815)
 Hardware engine can recognize touch tags and
track touch movement. Provides notification for
up to 255 touch tags.
 Enhanced sketch processing
 Built-in 12MHz crystal oscillator with PLL
providing programmable system clock up to
72MHz
 Support crystal-less operation with internal
relaxation clock source
 Video RGB parallel output; configurable to
support PCLK up to 72MHz and R/G/B output of
1 to 8 bits
 Programmable timing to adjust HSYNC and
VSYNC timing, enabling interface to numerous
displays
 Support for LCD display with resolution up to
SVGA (800x600) and formats with data enable
(DE) mode or VSYNC/HSYNC mode
 Support landscape and portrait orientations
 Display enable control output to LCD panel
 Integrated 1MByte graphics RAM, no frame
buffer RAM required
 Support playback of motion-JPEG encoded AVI
videos
 Mono audio channel output with Sigma-delta
modulation
 Built-in sound synthesizer
 Audio wave playback for mono 8-bit linear PCM,
4-bit ADPCM and µ-Law coding format at
sampling frequencies from 8 kHz to 48 kHz.
Built-in digital filter reduces the system design
complexity of external filtering
 PWM output for display backlight dimming
control
 Advanced object oriented architecture enables
low cost MPU/MCU as system host using SPI
interfaces
 Support SPI data lines in single, dual or quad
mode; SPI clock up to 30MHz
 Power mode control allows the chip to be put in
power down, sleep and standby states
 Supports I/O voltage from 1.8V to 3.3V
 Internal voltage regulator supplies 1.2V to the
digital core
 Built-in Power-on-reset circuit
 -40°C to 85°C extended operating temperature
range
 Available in a compact Pb-free, VQFN-64
package, RoHS compliant
