The PT6311-LQ is a VFD Driver/Controller IC from PTC, designed for microcomputer peripheral applications. It operates on a 1/8 to 1/16 duty factor and is housed in a 52-pin LQFP package.
This IC integrates a display memory, control circuit, and key scan circuit onto a single chip. It supports multiple display modes, ranging from 12 segments with 16 digits to 20 segments with 8 digits. The device features an 8-step dimming circuitry and provides 5 channels of LED ports with a maximum current of 20mA.
Communication with the PT6311-LQ is handled via a three-line serial interface, including clock, data input, and data output pins. It also includes 4 general-purpose input ports and key scanning capabilities for a 12x4 matrix. The design eliminates the need for external resistors for driver outputs, simplifying integration.
Key features include its CMOS technology for low power consumption and its ability to drive VFD displays efficiently. The 52-pin LQFP package is suitable for various electronic designs.
