Overview
VK16C22/VK16C22G is a memory mapped and multi-function LCD control/drive chip. The display mode of this series of chips has 176 points (44×4). The VK16C22/VK16C22G software configuration feature makes it suitable for a variety of LCD applications, including LCD modules and display subsystems. VK16C22/VK16C22G communicates with most microprocessors/microcontrollers through a two-wire bidirectional I2C interface.
The VK16C2X series are LCD control and driver ICs with I2C interface and RAM mapping. This series uses design techniques to reduce IC power consumption, improve noise immunity and ESD protection. The full range includes VK16C22/VK16C22G, VK16C23/VK16C23G, VK16C24/VK16C24G, etc. VK16C22 has been successfully approved and adopted by customers of single-phase electric meters. VK16C23 and VK16C24 are suitable for the application of three-phase electric meters with large points requirements.

LCD driver IC launched VK16C22 new I2C interface series.
The company focuses on TN/STN LCD small and medium size applications. The VK162X series of control and driver ICs have been marketed in the industry for many years. In 2010, Holtek launched the new product development of I2C standard interface series, this series includes VK16C22, VK16C23, VK16C24, VK16K23, etc. IC features emphasize low power consumption, high noise immunity and high system ESD protection capabilities, and are packaged with highly integrated pins to provide customers with large display points. VK16C22 is the first developed model, VK16C23, VK16C24 and VK16K23 will be launched one after another.
VK16C22 has built-in display memory and RC oscillator circuit; wide operating voltage: 2.4V~5.5V; 2 types of Bias voltage division: 1/2 & 1/3; large display points can support 4 Common x 44 Segment (52QFP). Provide 2 kinds of frame scanning frequency: 80Hz or 160Hz; VLCD voltage can be adjusted by external resistor, and 16-level VLCD voltage can be adjusted by built-in command. Through the I2C interface and multiple built-in circuits, the transmission between VK16C22 and the system control chip requires only 2 signal lines, which greatly saves system parts and wiring and reduces customer system costs. As with other products in the same packaging, VK16C22 provides more display points.
VK16C22 is suitable for the control and drive of LCD displays in home appliances, vehicles, consumer goods, industrial instruments, etc. It has high noise resistance and high ESD protection capabilities, especially suitable for digital LCD electric meters, water meters, gas meters, etc. Depending on the package, there are two points to choose from: 4 Common x 40 Segment (48 LQFP) and 4 Common x 36 Segment (44QFP).
