PT6963

DESCRIPTION PT6963 is an LED Controller driven on a 1/5 to 1/8 duty factor. 11 segment output lines, 4 grid output lines, 3 segment/grid output lines, one display memory, control circuit, key scan circuit are all incorporated into a single chip to build a highly reliable peripheral device for a single chip microcomputer. Serial data is fed to PT6963 via a four-line serial interface. Housed in a 32-pin SOP, PT6963 pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages. APPLICATIONS Micro-computer Peripheral Device VCR set Combo set BLOCK DIAGRAM PT6963 LED Driver IC FEATURES CMOS technology Low power consumption Multiple display modes (14 segment, 4 Grid to 11 segment, 7 Grid) Key scanning (10 x 3 Matrix) 8-Step dimming circuitry Serial interface for Clock, Data Input, Data Output, Strobe Pins and low voltage operation ability when user’s MCU power supply is 3.3V.

The capacitor (0.1µF) connected between the GND and the VDD pins must be located as close as possible to the PT6963 chip. 2. It is strongly suggested that the NC pin (pins 13) be connected to the GND. 3. The PT6963 power supply is separate from the application system power supply.
