RA6809 Brief Description:
RA6809 is a streamlined version of RA8889. Its MCU interface omits the parallel interface and I2C functionality, retaining only the SPI-3 and SPI-4 interfaces. Other features are basically the same as those of RA8889.
RA8889 Hardware Architecture:
RA6809 Main Features:
(1) Host Interface
- Supports serial host interface 3/4-wire SPI
(2) Input Display Data Format
- 1bpp: Monochrome (1-bit/pixel)
- 8bpp: RGB 3:3:2 (1-byte/pixel)
- 16bpp: RGB 5:6:5 (2-byte/pixel)
- 24bpp: RGB 8:8:8 (3-byte/pixel or 4-byte/pixel)
Index 2:6 (64 indexed colors/pixel with transparency attribute)
αRGB 4:4:4:4 (4096 indexed colors/pixel with transparency attribute)
αRGB 8:8:8:8 (8-bit alpha, 24bpp color depth)
(3) Display Mode
- User can set 24/18/16-bit TFT display output mode
- Supports screen resolution up to 1366*x pixels (Note: Actual panel resolution depends on pixel clock and color depth)
(4) Graphics Processing Functions
- Hardware decoding: Automatically recognizes JPEG, BMP and AVI formats; supports JPEG baseline profile, YUV444, YUV422, YUV420, YUV400 (does not support restart interval format)
- Picture-in-picture (PIP): Supports two PIP windows
- Flip display: Horizontal/vertical flip display function only applies to display, does not affect read/write of other functional blocks
- Geometric drawing: Supports drawing points, lines, curves, circles, ellipses, triangles, rectangles, rounded rectangles
- Block Transfer (BTE): Copy data with raster operations and color expansion, blend transparency, solid color extraction, graphic blend transparency, pixel blend transparency
(5) Text Functions
- Built-in ISO/IEC 8859-1/2/4/5. 12x24
- Supports Jietong serial font ROM
- Supports vertical and horizontal font magnification 2~4 times
- Supports text rotation by 90 degrees
(6) DMA Function
- Supports copying data from external serial flash to frame buffer
- Supports external flash Single/Dual/Quad mode
(7) PWM and Timer
- Built-in two 16-bit counters
- One 8-bit prescaler and one 4-bit frequency divider
- Output waveform duty cycle is programmable
- Auto-reload mode or one-shot mode
- Dead-zone protection
(8) Power Saving Modes:
- Supports 3 power saving modes
- Standby, Suspend, and Sleep modes
- Can be woken up by host, key press, or external event
- Wake-up display: If wake-up display effect is enabled, it can quickly display display data pre-stored in SDRAM upon wake-up
(9) Clock:
- Built-in programmable PLL
- Single crystal oscillator 10MHz
- Internal core maximum system frequency 120MHz
- SDRAM maximum frequency: 166MHz
