Vinka VK1640B LED Driver Datasheet
The VK1640B is a dedicated LED‑display driver for 8‑segment by 12‑grid matrices. It integrates a data latch, LED driver circuits, an internal 8×12‑bit display RAM, and an on‑power‑up reset. The chip operates from a 3.0 V to 5.5 V supply, provides eight levels of overall brightness adjustment, and uses a two‑wire serial interface (SCLK and DIN) for data transfer.
The device is supplied in an SSOP24 package (8.65 mm × 3.90 mm). Pin assignments include eight SEG pins for LED anodes, twelve GRID pins for LED cathodes, VDD, GND, SCLK, and DIN. Detailed command formats allow writing display data, setting brightness, and controlling the display on/off. Electrical characteristics such as supply voltage, power dissipation, output currents, and temperature ranges are listed in the datasheet. This manual is written in Chinese.
