DESCRIPTION PT6958 is an LED Controller driven on a 1/6 duty factor. Ten segment output lines, five 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 PT6958 via a three-line serial interface. Housed in a 28-pin SOP, PT6958’s pin assignments and application circuit are optimized for easy PCB Layout and cost saving advantages. FEATURES • CMOS Technology • Low Power Consumption • Up to 10 Segment Output Drivers • Up to 5 Grid Output Drivers • Key Scanning (6 x 4 Matrix) • 8-Step Dimming Circuitry • Serial Interface for Clock, Data Input, Data Output, Strobe Pins • Available in 28-pin, SOP APPLICATION • Micro-computer Peripheral Device
