R61509 display controller characteristics
Below is a brief introduction to the main characteristics for the R61509 RGB display controller (seen from a software driver design viewpoint).
For information about the R61509 driver software support please go to the library description.
R61509 device type
- COG RGB color display controller for use in small embedded systems with on-chip frame buffer and TFT screen driver.
- The R61509 supports TFT screens with a size up to 240 x 432 pixels (WxH)
- On-chip TFT driver with voltage generator
- RGB pixel resolution (bits per pixel): 16-bit, 18-bit.

Processor interfaces on R61509
R61509 parallel bus interface
- Parallel bus types: 8080 bus type
- Parallel bus size: 8-bit, 16-bit, 18 (32)-bit.
- Addressing concept: Indexed bus interface (1 chip select pin + 1 address bit pin (Data/Command))
Serial bus interfaces on R61509
- SPI bus: 3-wire: /CS, SDIN, SCLK. SPI-3 first byte in CS frame contains: device code, DC, RW. 16 bit transmission frame, (SPI only use 16 bits pr pixel mode)
- In SPI bus mode the frame buffer memory can not be read.
- The bus interfaces are all supported by the R61509 display driver software package.
Special R61509 hardware features:
- 0-180, 90-270 degree frame buffer rotation with hardware support. Portrait mode, landscape mode.
- Full driver software support.
