LCD Driver datasheet
The SPF54126A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of
supporting up to 176xRGBx220 in resolution which can be achieved by the designated RAM for graphic data. The 528-channel source
driver has true 6-bit resolution, which generates 64 Gamma-corrected values by an internal D/A converter. The source driver of
SPFD54126A adopts OP-AMP structure to enhance display quality and it cooperates with advanced circuitry techniques to reduce power
consumption.
The Inter IC bus or I2C bus is a simple bidirectional two wire bus designed primarily for general control
and data transfer communication between ICs.
Some of the features of the I2C bus are:
• Two signal lines, a serial data line (SDA) and a serial clock line (SCL), and ground are required. A
12V supply line (500mA max.) for powering the peripherals often may be present.
• Each device connected to the bus is software addressable by a unique address and simple
master/ slave relationships exist at all times masters can operate as master-transmitters or as
master-receivers.
• The I2C bus is a true multi-master bus including collision detection and arbitration to prevent data
corruption if two or more masters simultaneously initiate data transfer systems.
• Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 KBit/s in the standard
mode or up to 400 KBit/s in the fast mode.
All people curious about how Linux works and why it is so efficient will find answers here. After reading the book, you will find your way through the many thousands of lines of code,
distinguishing between crucial data structures and secondary ones—in short, becoming a true
Linux hacker.
